This chapter describes how to install the Cisco ASR 907 Router and includes the following sections:

Prerequisites

Before installing the Cisco ASR 907 Router, it is important to prepare for the installation by:

  • Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOP)
  • Unpacking and inspecting the Cisco ASR 907 Router
  • Gathering the tools and test equipment required to properly install the Cisco ASR 907 Router

For more instructions on how to prepare for the installation of the Cisco ASR 907 Router, see Preparing for Installation.

Installing the Router in a Rack

The following sections describe how to install the Cisco ASR 907 Router in a rack:

Installing the Chassis Brackets

The chassis is shipped with mounting brackets that can be installed on the front or rear of the chassis. To install the brackets on the front of the chassis, perform these steps:

Procedure


Step 1

Remove the rack-mount brackets from the accessory kit and position them beside the router chassis.

The figure below shows how to attach the brackets on the Cisco ASR 907 Router for a 19-inch EIA rack and 300 mm ETSI Cabinet.

Figure 1. Attaching Mounting Brackets for a 19-inch EIA Rack and 300 mm ETSI Cabinet


Step 2

Position one of the brackets against the chassis side, and align the screw holes.

Step 3

Secure the bracket to the chassis with the screws removed when performing Step 1. The recommended maximum torque is 28 in.-lb (3.16 N-m).

The A907-FAN-E fan tray with filter (A907-FAN-F) cannot be mounted using the mounting screws that are supported for fan tray. This is not an issue with the FAN tray filter blank panel (A907-FAN-F-B). We recommend that you use the short screws provided in the following rack mount kits to avoid interference of the air filter during rack mounting and while replacing the fan tray with the fan tray filter (A907-FAN-E):

  • 19" rack mount kit (A907-RCKMT-19IN)
  • ETSI rack mount kit (A907-RCKMT-ETSI)

What to do next

Repeat Step 2 and Step 3 for the other bracket.

Installing the Router Chassis in the Rack

The procedures in this section apply to both horizontal and vertical mounting of the router in a rack.

To install the router chassis in the equipment rack, perform these steps:

Procedure


Step 1

Position the chassis in the rack as follows:

  • If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between the mounting posts.

  • If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting posts.

Step 2

Align the mounting holes in the bracket (and optional cable guide) with the mounting holes in the equipment rack.

Caution

 

Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can deform or damage the handles. Installing the Chassis to support the Japanese JIS Rack Standard.

Grounding lug

To ensure that the chassis ground connection that you provide is adequate, you need the following parts and tools:


Note


Use 10 AWG copper wire for the power cord. For more information, see Connecting DC Power Supply Unit (A900-PWR900-D2).


  • Ratcheting torque screwdriver with Phillips head that exerts up to 20 in.-lb (2.25 N-m) of pressure for attaching the ground wire to the router

  • Crimping tool as specified by the ground lug manufacturer

  • 6 AWG or larger copper wire for the ground wire

  • Wire-stripping tools appropriate to the wire you are using


Caution


Before making connections to the Cisco ASR 907 Router, ensure that you disconnect the power at the circuit breaker. Otherwise, severe injury to you or damage to the router may occur.



Warning


This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024



Warning


Use copper conductors only. Statement 1025



Warning


When installing the unit, the ground connection must always be made first and disconnected last. Statement 42


This unit is to be installed in a restrictive access location and must be permanently grounded to minimum 6 AWG copper ground wire.

Perform the following procedure to ground the Cisco ASR 907 Router using a 2-hole lug and the corresponding mounting point. Most carriers require a minimum 6 AWG ground connection. Verify your carrier’s requirements for the ground connection.

Procedure


Step 1

If your ground wire is insulated, use a wire-stripping tool to strip the ground wire to 0.5 inch ± 0.02 inch (12.7 mm ±0.5 mm) As shown in the figure below.

Figure 14. Stripping a Ground Wire


Step 2

Slide the open end of your 2-hole ground lug over the exposed area of the ground wire.

Step 3

Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground wire as shown in figure below.

Figure 15. Crimping a Ground Lug onto the Ground Wire


Step 4

Use a Phillips head screwdriver to attach the 2-hole ground lug and wire assembly to the router with the 2 pan-head Phillips head screws. For a 19-inch EIA rack, attach the 2-hole ground lug to the rear of the router.

Step 5

Connect the other end of the ground wire to a suitable grounding point at your site.


Installing the Fan Tray

The fan tray is a modular unit that provides cooling to the Cisco ASR 907 Router.


Note


Do not introduce body parts or objects in the fan tray slot when installing or removing the fan tray module. Exposed circuitry is an energy hazard.

Follow these steps to install the fan tray in the chassis:

Procedure


Step 1

Orient the fan tray so that the captive screws are on the left side of the fan tray’s front panel. The figure below shows how to orient the fan tray.

Figure 16. Installing the Fan Tray


Step 2

Guide the fan tray into the chassis until it is fully seated.

Caution

 

The fans are exposed on the left side of the fan tray. Keep your fingers, clothing, and jewelry away from the fans. Always handle the fan tray by the handle.

Note

 
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling sufficient to allow for fan tray removal.

Step 3

Secure the fan tray to the chassis using the attached captive installation screws. The recommended maximum torque is 5.5 in.-lb (.62 N-m).

This completes the procedure for installing or replacing the fan tray in a Cisco ASR 907 Router.

Removing the Dust Filter

Remove the dust filter for a replacement.


Note


  • The dust filter is a single-use component.

  • Use the dust filter (A907-FAN-F) within 6 months of buying as the shelf or storage life is less than 6 months. The ideal storage condition for a filter is a cool, dry, and dark environment. Surroundings that adversely affect the dust filter are high heat, humidity at high temperatures, and ultraviolet light.


Dust Filter Maintenance

A periodic health check of the filter, every 3 months based on the level of dust in the environment, helps in avoiding over clogging of the filters and provides a better life. This product's filter is used as a single-use component. If the product is installed in a controlled environment, check and replace the filter every three months, otherwise replace the filter every month with PID (A907-FAN-F=) or equivalent.

Removing and Replacing the Fan Tray

The fan tray supports online insertion and removal (OIR). There is no need to power down the Cisco ASR 907 Router to remove or replace the fan tray. However, the router will shut down if the fan tray is removed from the chassis for more than 90 seconds at 25º C due to thermal overload condition. Approximately at 25º C the system powers back in 2 minutes.


Note


If a fan tray is removed and not replaced within the stipulated time the system will automatically power-off. If the system is powered with PSUs other than 900W DC or 1200W AC and if the system is powered off, then the system should be completely powered off for 30 seconds with all the PSU in the system simultaneously, and then turned on for the system to power on.

Note


Do not introduce body parts or objects in the fan tray slot when installing or removing the fan tray module. Exposed circuitry is an energy hazard.

Caution


The router can stay active for up to 60 seconds if the temperature is up to 30º C. However, in the event of an overtemperature alarm, the router can shut down in less than 60 seconds. In the event of a critical temperature alarm, the router shuts down immediately.



Caution


To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after the fan tray has been replaced.


Follow these steps to remove and replace the fan tray on the Cisco ASR 907 Router:

Procedure


Step 1

Using a No. 2 Phillips screwdriver or your fingers, loosen the captive installation screw that secures the fan tray to the chassis. The figure below shows the front of the fan tray, including the captive installation screws.

Figure 19. Detaching the Fan Tray

Step 2

Grasp the fan tray handle with one hand and the outside of the chassis with the other hand. The figure above shows the front of the fan tray, including the handle.

Caution

 

The fans are exposed on the left side of the fan tray. Keep your fingers, clothing, and jewelry away from the fans. Always handle the fan tray by the handle.

Step 3

Pull the fan tray toward you no more than 1 inch to disengage it from the power receptacle on the midplane, as shown in the figure below.

Figure 20. Fan Tray Removal


Warning

 
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258

Step 4

Wait at least 5 seconds to allow the fans to stop spinning. Then, pull the fan tray backward toward you and out of the chassis.

Note

 
As the fan tray slides out of the chassis, support the bottom of the fan tray with one hand and keep your other hand on the fan tray handle.

This completes the steps for removing the fan tray from the chassis.

Note

 
The chassis must not be allowed to operate without functioning fans for more than 60 seconds.

To install the new fan tray, follow the steps in Installing the Fan Tray .


RSP Installation

Follow these steps on handling an RSP module in the Cisco ASR 907 Router:

Installing an RSP Module

To install an RSP module in the router chassis, perform the following steps:

Procedure


Step 1

Choose a slot for the module. Make sure that there is enough clearance to accommodate any equipment that will be connected to the ports on the module. If a blank module filler plate is installed in the slot in which you plan to install the module, remove the plate by removing its 2 Phillips pan-head screws.

Step 2

Fully open both the ejector levers on the new module, as shown in the figure below.

Caution

 

To prevent ESD damage, handle modules by carrier edges only.

Step 3

Position the module in the slot. Make sure that you align the sides of the module with the guides on each side of the slot, as shown in the figure below.

Figure 21. Cisco ASR 907 Router RSP Installation


Step 4

Carefully slide the module into the slot until the EMI gasket on the module makes contact with the module in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with respect to the module faceplate.

Caution

 

If the top slot already has an RSP module installed, and you install a second RSP module in the slot below it, be careful not to damage the EMI gasket of the bottom RSP module against the ejector levers of the top RSP during insertion.

Step 5

While pressing down, simultaneously close both the ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.

Step 6

Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5 in.-lb (.62 N-m).

Note

 

Make sure that the ejector levers are fully closed before tightening the captive installation screws.

Step 7

Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step ensures that the EMI gaskets on all the modules are fully compressed in order to maximize the opening space for the new or replacement module.

Note

 

If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, which reduces the size of the opening and makes it difficult to install the new module.

Caution

 

Blank module filler plates (Cisco part number A90X-RSPA-BLANK-W) should be installed in any empty chassis slots to keep dust out of the chassis and to maintain consistent airflow through the chassis.

Note

 

When installing the cabling to an RSP, we recommend that you leave a service loop of extra cabling sufficient to allow for fan tray removal.

Note

 

Close all unused RJ-45 and USB ports on the RSP module using the appropriate dust caps to prevent dust from accumulating inside the cage. For information on dust caps, see Installing Dust Caps.


Removing an RSP Module

Before you remove an RSP from the router, you should save the current configuration on a TFTP server or an external USB flash drive, using the copy running-config {ftp | tftp | bootflash: } command. This saves you time when bringing the module back online.

If the module is running Cisco IOS software, save the current running configuration by entering the copy running-config startup-config command.


Warning


Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Warning


Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051


To remove an RSP module, perform the following steps:

Procedure


Step 1

Disconnect any cables attached to the ports on the module.

Step 2

Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures that the space created by the removed module is maintained.

Note

 
If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, which in turn reduces the size of the opening and makes it difficult to remove the module.

Step 3

Loosen the two captive installation screws on the module you plan to remove from the chassis.

Step 4

Place your thumbs on the ejector levers (see ) and simultaneously rotate the ejector levers outward to unseat the module from the backplane connector.

Step 5

Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has horizontal slots, place your hand under the module to support its weight as you slide it out from the slot. Do not touch the module circuitry.

Caution

 

To prevent ESD damage, handle modules by the carrier edges only.

Step 6

Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another slot.

Step 7

Install blank module filler plates (Cisco part number A90X-RSPA-BLANK-W) in empty slots, if any.

Warning

 

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029


Hot-Swapping an RSP Module

The Cisco ASR 907 Router provides a feature that allows you to remove and replace a redundant RSP module without powering down the router. This feature, called hot-swapping or OIR, allows you to remove and replace a redundant module without disrupting router operation.

When two redundant modules are installed in the router, only one of the modules is active. The other one runs in standby mode, ready to take over processing if the active module fails.

When you remove or insert a redundant module while the router is powered on and running, the router does the following:

  1. Determines if there is sufficient power for the module.
  2. Scans the backplane for configuration changes.
  3. Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively shutdown state.
  4. Places any previously configured interfaces on the module back to the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shutdown state as if they were present (but unconfigured) at boot time. If you insert the same type of module into a slot, its ports are configured and brought online up to the port count of the original module.

The router runs diagnostic tests on any new interfaces and the test results indicate the following:

  • If the tests pass, the router is operating normally.
  • If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.
  • If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a problem in the bus and should be removed.

Use the following guidelines when performing an OIR on an IM:

  • Allow at least 2 minutes for the system to reinitialize before inserting a new IM.
  • Avoid inserting a new IM during bootup until the active and standby RSPs have reached an OK state.
  • When inserting multiple IMs into the chassis, wait until each IM reaches an OK state before inserting the next IM.

Installing the Interface Module Carrier


Note


It is recommended that you always install the IM carrier (A9XX-2IMA-CARRIER) in the lower slot before installing the carrier in the upper slot.

Procedure


Step 1

Before inserting an IM carrier, make sure that the chassis is grounded.

Step 2

To insert the IM carrier, carefully align the edges of the IM carrier between the upper and lower edges of the router slot.

Step 3

Carefully slide the IM carrier into the router slot until the IM carrier makes contact with the backplane. See the figure below.

Figure 22. Installing the IM Carrier



Interface Module Installation

The following sections describe the various tasks of associated with interface module installation on the Cisco ASR 907 Router:

Installing an Interface Module

Procedure


Step 1

Before inserting an interface module, make sure that the chassis is grounded.

Step 2

To insert the interface module, carefully align the edges of the interface module between the upper and lower edges of the router slot.

Step 3

Carefully slide the interface module into the router slot until the interface module makes contact with the backplane. The figure below shows how to install the interface module.

Figure 23. Inserting an Interface Module


Caution

 

Use the pull tab on the interface module only to insert and pull the card out straightly. Don’t use the pull tab to turn on its axis or bend it up or down, which can deform or damage the pull tab.

Figure 24. Using the Pull Tab
Use the pull tab on the interface module only to insert and pull the card out straightly.

Step 4

Tighten the locking thumbscrews on both sides of the interface module. The recommended maximum torque is 5.5 in.-lb (.62 N-m).

Step 5

Connect all the cables to each interface module.


What to do next


Caution


Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can deform or damage the handles.



Note


Close all unused RJ-45, SFP, XFP, and QSFP ports on the interface module using the appropriate dust caps to prevent dust from accumulating inside the cage. For information on dust caps, see Installing Dust Caps .

Removing an Interface Module

Procedure


Step 1

To remove an interface module, disconnect all the cables from each interface module.

Step 2

Loosen the locking thumbscrews on both sides of the interface module.

Step 3

Slide the interface module out of the router slot by pulling on the handles. If you are removing a blank filler plate, pull the blank filler plate completely out of the router slot using the captive screws.


Hot-Swapping an Interface Module

The Cisco ASR 907 Router provides a feature that allows you to remove and replace an interface module without powering down the router. This feature, called hot-swapping or OIR, allows you to remove and replace a redundant module without disrupting router operation.


Note


The Cisco ASR 907 Router does not support hot-swapping an interface module with another module of a different type. For example, you cannot swap an SFP Gigabit Ethernet module with a copper Gigabit Ethernet module without disrupting router operation.



Note


If the TDM interface module is swapped with the Gigabit Ethernet module in the same slot or vice-versa, the router must be reloaded.



Note


If you perform OIR on an interface module and move the module to a different slot, the router does not retain the module configuration; you must reconfigure the interface module. Replacing a configured interface module with a different interface module in the same slot is not supported on the router.



Note


Always refer to the interface module compatibility matrix tables in the Data Sheet before you swap any IM.

When you remove or insert a redundant module while the router is powered on and running, the router does the following:

  1. Determines if there is sufficient power for the module.

  2. Scans the backplane for configuration changes.

  3. Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively shutdown state.

  4. Places any previously configured interfaces on the module back to the state they were in when they were removed.

The router runs diagnostic tests on any new interfaces and the test results indicate the following:

  • If the tests pass, the router is operating normally.

  • If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.

  • If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a problem in the bus and should be removed.

Caution


To avoid erroneous failure messages, note the current configuration of all interfaces before you remove or replace an interface module, and allow at least 2 minutes for the system to reinitialize after a module has been removed or replaced. This time is recommended in order to allow for synchronization between components within the interface module and for synchronization with the standby RSP.


Installing the Power Supply

The Cisco ASR 907 router provides the choice of two different power supplies:


Attention


The RSP3-400-W requires only two PSUs (either AC or DC). We recommended you to use only two PSUs with RSP3-400-W in any of the two slots of ASR 907 router.


  • 1200 W DC power: - 40.8VDC to -72VDC

    The DC power supply uses 3 position terminal block-style connector with positive latching or securing and labeled connections for 48V, GRD, 48V. The terminal block connector is of suitable size to carry the appropriate AWG wire size to handle the input current of the power supply. No ON/OFF switch is provided.

  • AC power: 85VAC to 264VAC

    The AC power supply has an IEC-320-C21-type power receptacle and a 20-A service connector. You can use standard right angle power cords with the AC power supply. The power supply includes a power cord retainer. No ON/OFF switch is provided.


Caution


The power supply must be wired before plugging the power supply in the chassis. Ensure that the branch circuit breaker is turned off. Only after installing the power supply in the chassis, should the branch circuit breaker be turned on. The branch circuit breaker must be turned off before unplugging the power supply.


Each power supply provides a single primary input power connection. You can install dual power supplies for redundancy.


Warning


Read the installation instructions before connecting the system to the power source. Statement 10



Note


Products that have an AC power connection are required to have an external surge protective device (SPD) provided as part of the building installation to comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety.



Caution


Do not use the interface module and power supply ejector handles to lift the chassis. Using the handles to lift the chassis can deform or damage the handles.


Preventing Power Loss

Use the following guidelines to prevent power loss to the router.

  • To prevent loss of input power, ensure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.
  • In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Cisco ASR 907 Router, which can have substantial current draw fluctuations due to bursty data traffic patterns.

Use the information in the DC Power Supply Specifications table to estimate the power requirements and heat dissipation of a Cisco ASR 907 Router based on a given configuration of the router. Determining power requirements is useful for planning the power distribution system needed to support the router.

Power Connection Guidelines

This section provides guidelines for connecting the Cisco ASR 907 Router power supplies to the site power source.


Warning


Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 213



Warning


The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. Statement 1019



Note

Connecting a Management Ethernet Cable

When using the Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through cable and adapts to it.

However, when the Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-line interface (CLI) commands, the port is forced to MDI mode.

When in a fixed-speed configuration and MDI mode:

  • Use a crossover cable to connect to an MDI port
  • Use a straight-through cable to connect to an MDI-X port

Warning


To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Management Ethernet ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.


Installing and Removing SFP and XFP Modules

The Cisco ASR 907 Router supports a variety of SFP and XFP modules, including optical and Ethernet modules. For information on how to install and remove SFP and XFP modules, see the documentation for the SFP or XFP module at

http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html

For information about inspecting and cleaning fiber-optic connections, see http://www.cisco.com/en/US/partner/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml


Caution


We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface module. This time is recommended to allow the transceiver software to initialize and synchronize with the standby RSP. Changing an SFP more quickly could result in transceiver initialization issues that disable the SFP.


Connecting a USB Flash Device

Connecting Ethernet Cables

The Cisco ASR 907 Router interface modules support RJ45 or SFP Ethernet ports. For instructions on how to connect cables to Ethernet SFP ports, see Connecting Cables to SFP Modules .

The RJ45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables. Cisco Systems does not supply Category 5 UTP cables; these cables are available commercially.


Warning


To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Gigabit Ethernet ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.



Note


When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling sufficient to allow for fan tray removal.

Follow these steps to connect the cable to a copper Gigabit Ethernet port:

Procedure


Step 1

Confirm that the router is powered off.

Step 2

Connect one end of the cable to the Gigabit Ethernet port on the router.

Step 3

Connect the other end to the BTS patch or demarcation panel at your site.


Connecting T1/E1 Cables

The physical layer interface for the Cisco ASR 907 Router T1/E1 port is a customer-installed high-density connector. The high-density connector has thumbscrews which should be screwed into the interface when the cable is installed.


Note


Patch panels are required in order to connect the high-density interface connectors to individual T1/E1 lines.

Installing the Cable Connectors

T1/E1 Cable Connectors

One end of the cable (see the figure above) has a 68-pin connector that plugs into the T1/E1 interface module and the other end of the cable with a 68-pin connector is connected to a RJ48, AMP64 or a DIN patch panel. Use the thumbscrews on either side of the connector to secure the cable to the interface.

Figure 32. T1/E1 Cable Connector
16 x T1/E1 Cable Connectors
Figure 33. 16 x T1/E1 Cable Connector


One end of the cable (see the figure above) has a 100-pin connector that plugs into the T1/E1 interface module. Use the thumbscrews on either side of the connector to secure the cable to the interface.

The other end of the cable has two 50-pin Telco connectors that attach to the rear of a 24-port RJ45 patch panel. Both connectors are identical: one is for Transmit (TX) and the other is for Receive (RX).

The figure below shows how the cable is connected between the 16 x T1/E1 interface module and the patch panel.

Patch panel interfaces

For information about the pinout of the cable connecting the T1/E1 interface to the rear of the patch panel, see the T1/E1 Port Pinout.

32 x T1/E1 Cable Connector
Figure 35. 32 x T1/E1 Cable Connector


The 32 x T1/E1 interface module requires two patch cables. Each patch cable has a 68-pin connectors that connects with each connector port on the front panel of the 32 x T1/E1 interface module.

Use the thumbscrews on either side of the connectors to secure the cable to the interface.

The other end of the cable has two 50-pin Telco connectors that attach to the rear of a 24-port RJ45 patch panel. Both connectors are identical: one is for Transmit (TX) and the other is for Receive (RX).

The figure below shows how the cable is connected between the 32 x T1/E1 interface module and the patch panel.

T1/E1 Pinouts

For information about the pinout of the cable connecting the T1/E1 interface to the rear of the patch panel, see the T1/E1 Port Pinout .

RJ45 Cable Pinouts

T1 lines from individual subscribers are attached to RJ45 connectors on the front of the 24-port patch panel. Each RJ45 port accommodates an individual T1 subscriber line.

For the T1/E1 ports, see the T1/E1 Port Pinout .

RJ48 Cable Pinouts

T1 lines from individual subscribers are attached to RJ45 connectors on the front of the 24-port patch panel. Each RJ45 port accommodates an individual T1 subscriber line.

For the T1/E1 ports, see the T1/E1 Port Pinouts (RJ-48) section.

Connecting Cables to the Patch Panel

If you are connecting two T1/E1 interfaces to each other, you must cable both interfaces’ patch panels together using a T1 cross-over cable or a T1 straight-through cable. Use shielded cables. The type of cable you use (cross-over or straight-through) depends on how the T1/E1 interfaces are cabled to their patch panels:

  • If both T1/E1 interfaces are connected to their patch panels in the same manner (TX to Transmit and RX to Receive, or TX to Receive and RX to Transmit), use a T1 cross-over cable to connect the patch panels.
  • If both T1/E1 interfaces are connected to their patch panels in a different configuration (TX to Transmit and RX to Receive on one interface, and TX to Receive and RX to Transmit on the other interface), use a T1 straight-through cable (standard RJ45 patch cable) to connect the patch panels.

Warning


To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the T1/E1 ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Patch Panel Cabling for Redundancy

You can connect the patch panels with the interface modules for redundancy, using the Y-cables. The Y-cable stub lengths are reduced, so that the cable does not exceed from the rack spacer. The Y-cables are numbered based on the different stub length. Cable lengths differ for even numbered and odd numbered slots in the chassis.


Note


Do not try to interchange the cables as the length may vary based on odd and even slots.

Connecting the Fan Tray Alarm Port

The fan tray includes an alarm port that maps to 4 dry contact alarm inputs.

The pins on the alarm port are passive signals and can be configured as Normally Open (an alarm generated when current is interrupted) or Normally Closed (an alarm is generated when a circuit is established) alarms. You can configure each alarm input as critical, major, or minor. An alarm triggers alarm LEDs and alarm messages. The relay contacts can be controlled through any appropriate third-party relay controller. The open/close configuration is an option controlled in IOS.


Warning


To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the alarm ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.


Only Pins 1, 2, 4, 6, and 8 are available for customer use. The remaining pins are for Cisco manufacturing test, and should not be connected. Use a shielded cable for connection to this port for EMC protection. To understand the pinouts on the alarm port in Troubleshooting.

Procedure


Step 1

Attach an RJ45 cable to the alarm port.

Step 2

Attach the other end of the RJ45 cable to the relay controller.


What to do next

For information about how to map alarm inputs to critical, major, and minor alarm conditions, see the Cisco ASR 907 Router Software Configuration Guide .
