Power Supply Features
The Cisco ASR 902 Router supports AC and DC power supplies. These power supplies have the following features:
Redundancy
The Cisco ASR 902 Router chassis includes a slot for optional redundant power supply. The redundant power supply option provides a second power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails. Redundancy is supported either with identical power supplies or a combination of AC and DC power supply.
Dying Gasp
This feature allows the router to provide an input power loss notification to the RSP so that the RSP can send appropriate SNMP traps or OAM messages and update log files on the router.
Status LEDs
The LEDs indicate the status of the input power and the health of the power supply.
Fan Tray Features
The fan tray has the following hardware features:
It provides side-to-side forced air cooling
It provides redundant fans
It is field replaceable
It contains status LEDs
It contains two alarm ports with two external alarm inputs
Dust Filter
The dust filter on the fan tray is a quadrafoam 45PPI filter that is 85 percent dust resistant. A dummy cover (A902-FAN-F-B) secures the dust filter in the chassis.
RSP Modules
The Cisco ASR 902 Router is designed to use a single RSP module to handle the data plane, network timing, and control plane functionalities for the router. The RSP configuration allows you to use Cisco IOS software to control chassis management, external management, and system status indications on the router.
RSP features include:
- Loading software onto processor-based interface modules
- Packet processing
- Traffic management, including buffering, queuing, and scheduling, Ethernet MAC functions.

- Field replacement
GNSS Module (A900-CM-GNSS)
The GNSS module is present on the RSP3 modules. It is a pluggable module that allows direct interface with the external antenna.
DANGERTo reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Note
The GNSS module is not hot swappable.GNSS Module RF Input Requirements
- The GNSS module requires an active GPS/GNSS antenna with built-in Low-Noise Amplifier (LNA) for optimal performance. The antenna LNA amplifies the received satellite signals for two purposes:
Compensation of losses on the cable
Lifting the signal amplitude in the suitable range for the receiver frontend
The Amplification required is 22dB gain + cable/connector loss + Splitter signal loss.
The recommended range of LNA gain (LNA gain minus all cable and connector losses) at the connector of the receiver module is 22dB to 30dB with a minimum of 20dB and a maximum of 35dB.
GNSS module provides 5V to the active antenna through the same RF input.
Surge requirement:
GNSS modules have built-in ESD protections on all pins, including the RF-input pin. However, additional surge protection may be required if rooftop antennas are being connected, to meet the regulations and standards for lightning protection in the countries where the end-product is installed.
A lightning protection must be mounted at the place where the antenna cable enters the building. The primary lightning protection must be capable of conducting all potentially dangerous electrical energy to PE (Protective Earth).
Surge arrestors should support DC-pass and suitable for the GPS frequency range (1.575GHz) with low attenuation.
Antenna Sky visibility:
GPS signals can only be received on a direct line of sight between antenna and satellite. The antenna should see as much as possible from the total sky. For proper timing, minimum of four satellites should be locked.
Note
The antenna terminal should be earthed at the building entrance in accordance with the ANSI/NFPA 70, the National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable.
Use a passive splitter if more than one GNSS modules are fed from a single antenna.
Note
The splitter should have all the RF ports capable of DC-pass, if the antenna needs to feed power from GNSS module.Interface Modules
The Cisco ASR 902 Router interface modules are field-replaceable units.
Note
On RSP-1, Slot 2 Port 0 cannot be used for traffic flow on 8X1-G copper and 8X1-G SFP interface modules.In addition to the ports provided on an RSP, the Cisco ASR 902 Router supports the following interface modules:

Warning
When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
This unit is to be installed in a restrictive access location and must be permanently grounded to a minimum 6-AWG copper ground wire.
Perform the following procedure to ground the Cisco ASR 902 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.
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) ( the figure below ). 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 the figure below. 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
ProcedureThe fan tray is a modular unit that provides cooling to the Cisco ASR 902 Router. Follow these steps to install the fan tray in the chassis:
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. 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 RSP, 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 902 Router.
For information about connecting cables to the fan tray alarm port, see the Connecting the Fan Tray Alarm Port section in the Cisco ASR 902 and ASR 902U Aggregation Services Router Hardware Installation Guide. For a summary of the LEDs on the fan tray, see the LED Summary section in the Cisco ASR 902 and ASR 902U Aggregation Services Router Hardware Installation Guide. For more information about air flow guidelines, see the Air Flow Guidelinessection in the Cisco ASR 902 and ASR 902U Aggregation Services Router Hardware Installation Guide.
Installing the Dust Filter
Procedure
Step 1 Remove the fan tray (if installed) from the chassis. Step 2 Remove the dummy cover from the fan tray. Step 3 Slide the dust filter onto the fan tray. Step 4 Insert the dummy cover on the fan tray to secure the filter within the chassis. Step 5 Perform the steps to install the fan tray in the chassis. See the Installing the Fan Tray section.
RSP Installation
Follow these steps pertaining to handling an RSP module in the Cisco ASR 902 Router:
Installing an RSP Module
Procedure
Step 1 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 . 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).
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 towards the open slot, which reduces the size of the opening and makes it difficult to install the new module.
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 the Installing the Dust Caps section.
Interface Module Installation
The following sections describe the various tasks associated with interface module installation on the Cisco ASR 902 Router:
Installing an Interface Module
Procedure
Note
On RSP-1, Slot 2 Port 0 cannot be used for traffic flow on 8X1-G copper and 8X1-G SFP interface modules.
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.
Caution Do not use interface module or power supply ejector handles to lift the chassis; using these handles to lift the chassis can deform or damage the handles.

Step 1 Connect the end of the console cable with the RJ45 connector to the light blue console port on the router. or
Connect a USB Type A-to-Type A cable to the USB console port, as shown in the figure below. If you are using the USB serial port for the first time on a Windows-based PC, install the USB driver now according to the instructions in the following sections:
Note You cannot use the USB port and the EIA port concurrently. See the Connecting to the Auxiliary Port. When the USB port is used, it takes priority over the RJ45 EIA port.
Note The USB Type A-to-Type A cable is not included with the Cisco ASR 902 Router; it is ordered separately.
Step 2 Connect the end of the cable with the DB-9 connector (or USB Type-A) to the terminal or PC. If your terminal or PC has a console port that does not accommodate a DB-9 connector, you must provide an appropriate adapter for that port. Step 3 To communicate with the router, start a terminal emulator application, such as Microsoft Windows HyperTerminal. This software should be configured with the following parameters:
Powering Up the Cisco Router
ProcedureMake certain that all card slots and compartments are closed off. Install blank faceplates on any empty slots. Always have power supply slots filled. If you leave a power supply slot uncovered, then you risk exposure to hazardous voltages on the power pins on the midplane.
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
After installing your Cisco Router and connecting cables, start the router and follow these steps:
Step 1 Activate the DC power supply using the steps described in Activating the DC Power Supply.
Caution Do not press any keys on the keyboard until the messages stop and the SYS PWR LED is solid green. Any keys pressed during this time are interpreted as the first command typed when the messages stop, which might cause the router to power off and start over. It takes a few minutes for the messages to stop.
