Empty card slots or card bays are filled with card blanks. This ensures proper air flow through the chassis
and electromagnetic compatibility (EMC).
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.
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
Warning
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
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.
Caution
This is only an example of what can display. The system boots differently depending upon the configuration
that ships with your system.
Note
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
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
Installing and Upgrading Software section in the High Availability
Configuration Guide, Cisco IOS XE Release 3S (ASR 900)
