|
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.
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:
| 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. 
|
||||

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

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 ) 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 A90X-RSPA-BLANK-W) in empty slots, if any.
|
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:
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
Use the following guidelines when performing an OIR on an IM:
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. |
| 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.  |
The following sections describe the various tasks of associated with interface module installation on the Cisco ASR 907 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 |
ITighten 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. |
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 . |
| 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 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:
Determines if there is 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 administratively shutdown state.
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.
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. |
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. |
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.
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.

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:
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 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.
| 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 907 Router Software Configuration Guide .
