Checking the Installation

Step 8 If you disconnected cables to remove the PRP, or if you are installing a new PRP, reconnect the cables

to the appropriate ports. (See the “Checking the Installation” section on page 23.)

Step 9 Ensure that the console terminal is turned on.

Step 10 Turn on system power.

Step 11 Attach the network end of your RJ-45 cable to your transceiver, switch, hub, repeater, DTE, or other

external equipment. Be sure to use the appropriate strain relief on cable connections.

Checking the Installation

This section assists you in confirming that the PRP is installed successfully and includes the following

PRP Boot Process

The following sequence describes a typical PRP boot process:

1. System power is turned on.

2. MBus module receives +5 VDC and starts executing MBus software.

3. PRP determines the system configuration by sending a message over the MBus requesting all

installed devices to identify themselves. The return response provides slot number, and card and

component type. The PRP, line cards, and clock scheduler cards (CSCs) are then powered up.

4. PRP power-on-reset logic delay, which allows power and both local and CSC clocks to stabilize.

5. After the power-on reset is released, the PRP begins to execute the ROM monitor software.

6. If the ROM monitor is configured to autoboot, it loads and boots the Cisco IOS software.

If the ROM monitor is not configured to autoboot, you must enter the appropriate b command at the

ROM monitor prompt (

Rommon>) to boot the Cisco IOS software.

7. When the Cisco IOS software boots, it polls all other cards in the system and powers them up,

loading their Cisco IOS software as needed.

Starting the System and Observing Initial Conditions

This section describes the initial system startup processes and procedures.

To start your system, follow these steps:

Step 1 Turn on each installed power supply by turning its system power switch to the on (|) position.
