Chapter 3 Installing the Cisco ASR 901 Mobile Wireless Router

Powering On the Router

For more information about 10Mhz and 1PPS port pinouts, see “GPS Port Pinouts” section on page B-6.

Connecting Cables to the ToD Interface

Complete these steps to connect cables to the ToD interface for GPS timing.

Step 1 Confirm that the router is powered off.

Step 2 Connect one end of a straight-through Ethernet cable to the GPS unit.

Step 3 Connect the other end of the cable to the ToD port on the Cisco ASR 901 router.

For instructions on how to configure clocking, see the Cisco ASR 901 Router Software Configuration Guide.

Note For more information about BITS port pinouts, see “Time of Day Pinouts” section on page B-6.

Connecting to Alarm Port

Use a straight cable to connect to the alarm port. For details on the pinouts, see “Alarm Port Pinouts” section on page B-7.

Connecting to the Management Ethernet Port

Use a straight or a cross over ethernet cable to connect to the management ethernet port. For details on the pinouts, see “Management Ethernet Port Pinouts” section on page B-7.

Dressing Router Cables

Ensure all Cisco router cables are properly dressed so as not to interfere with each other or other pieces of equipment. Use local practices to ensure that the cables attached to your router are properly dressed.

Note If your Cisco ASR 901 router is front-mounted, you can use the cable guide (found in the accessory kit) to dress the cables.

To continue the installation, proceed to the next section, “Powering On the Router.”

Powering On the Router

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. Statement 4
