The fan tray supports online insertion and removal (OIR). There is no need to power down the Cisco ASR 903 Router to remove or replace the fan tray. However, there is a finite time to replace the fan tray. This time depends upon the specific RSP and fan tray combination and also the ambient temperature. The following table provides the time interval for replacing the fan tray. At higher ambient temperatures, the replacement time is lower.
Note |
If a fan tray is removed, and not replaced within the stipulated time the system will automatically power-off. The actual shutdown time depends on few parameters like the total traffic load, ambient temperature, type of fan tray that is used and the dust filter condition (if a filter is present). 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 |
If the system shuts down due to overheating, the removed fan tray must be reinserted before powering up the system. After the system is online, the alarms generated before the shutdown must be cleared in the Cisco Evolved Programmable Network Manager (EPNM) or any other server manager used to manage the device. |

This completes the steps for removing the fan tray from the chassis. To install the new fan tray, follow the steps in Installing the Fan Tray. |
Follow these steps on handling an RSP module in the Cisco ASR 903 Router:
To install an RSP module in the router chassis, perform the following steps:
|
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.
|
||||||||
|
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 .  |
||||||||
|
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.
|
||||||||
|
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).
|
||||||||
|
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.
|
Before you remove an RSP from the router, you should save the current configuration using the write {host file | network | terminal} 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:
|
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.
|
||
|
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 the figure Cisco ASR 903 Router RSP Installation ) 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.
|
||
|
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 A900-RSPA-BLANK) in empty slots, if any.
|
The Cisco ASR 903 Router provides a feature that allows you to remove and replace a redundant RSP module without powering down the router. This feature is 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:
Determines if there’s sufficient power for the module
Scans the backplane for configuration changes.
Initializes the newly inserted module In addition, the system notes any removed modules and places those modules in the administrative shutdown state.
Places any previously configured interfaces on the module to the state that they were in when they were removed. Any newly inserted interfaces are put in the administrative 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.
Note |
Before performing a hot-swap of the redundant RSP module, ensure the following to avoid system failure:
|
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.
The following sections describe the various tasks of associated with interface module installation on the Cisco ASR 903 Router:
|
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. 
|
||||||||
|
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.
|
|
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. |
The Cisco ASR 903 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.
Use the following guidelines when performing an OIR on an IM:
The following interface modules take around 60 to 70 seconds to reach OK state after a soft OIR is performed:
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.
When you remove or insert a redundant module while the router is powered on and running, the router does the following:
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
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. |

Step 4 |
Make sure that your modem and the router auxiliary port are configured for the same transmission speed (up to 115200 bps is supported) and for mode control with data carrier detect (DCD) and data terminal ready (DTR) operations. |
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. |
The Cisco ASR 903 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:

The physical layer interface for the Cisco ASR 903 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. |
The 16 x T1/E1 interface module requires a patch cable (see Recommended Patch Panel). One end of the cable (see the figure below ) 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.

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

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 T1/E1 Port Pinout.
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:
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. |

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, 5, 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. Table 5-6 summarizes the pinouts on the alarm port in Troubleshooting.
|
Step 1 |
Attach an RJ45 cable to the alarm port. |
|
Step 2 |
Attach the other end of the RJ45 cable to the relay controller. |
For information about how to map alarm inputs to critical, major, and minor alarm conditions, see the Cisco ASR 903 Router Software Configuration Guide.
