Powering On the Router

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Statement 39

Checklist for Power Up

Complete these steps to power on the Cisco ASR 901 router:

•Securely mount the router.

•Properly connect the power, network, and interface cables.

Interpreting Front-Panel LEDs

The Cisco ASR 901 router provides a number of LEDs on the front panel to monitor conditions and to aid in troubleshooting problems. For a description of the LEDs, see the “Reading the LEDs” section on page A-4.

Power-On Procedure

Complete these steps to power on the Cisco ASR 901 router and verify its initialization and self-test:

Step 1 Remove the tape from the circuit breaker switch handle.

Step 2 Restore power by moving the handle of the circuit breaker to the ON position.

The LED (labeled POWER) on the front panel should go ON and the fans operate.

Depending on your installation, other front-panel LEDs can also come on.

Note When the Cisco ASR 901 1G router (DC unit) is powered ON, it takes about 30 seconds for the system LED to turn ON.

Note If you encounter problems when you power on the router, see Appendix A, “Troubleshooting”.

Formatting Procedures for Flash Memory

We recommend that you erase (Class B) to initialize with a Class B Flash file system.

The Class B Flash file system is also known as the low end file system (LEFS).

Formatting Flash Memory as a DOS File System

To format the flash memory, or to remove the files from it, use the erase flash: command.
