Powering Up the Cisco ASR 903 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 ASR 903 Router and connecting cables, start the router and follow these
steps:
Step 1 Activate the DC power supply using the steps described in “Activating the DC Power Supply” procedure
on page 3-23.
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.
Note This is only an example of what can display. The system boots differently depending upon
the configuration 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 ASR 903 Router RSP begins to initialize.
