Powering Up the Cisco Router

• Empty card slots or card bays are filled with card blanks. This ensures proper air flow through the chassis

Powering Up the Cisco Router

Make 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

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.

This is only an example of what can display. The system boots differently depending upon the configuration

Note

that ships with your system.

Step 2

Observe the initialization process. When the system boot is complete (the process takes a few seconds), the Cisco Router

RSP begins to initialize.

The boot image is located in a partition of the bootflash directory. Post initial system boot, depending on your

Note

requirement, you must configure the system boot variable to either bootflash:/Image/packages.conf (for

sub-package mode boot) or bootflash:/Image/image_name (for consolidated mode boot). For more information

about software package modes, see the
