Applying Power to the Server
Observe the functionality of the server before attaching any LAN or serial cables, the system
console, or any peripherals to the server. Then, after applying an active AC power source to the
server, make the following observations at three different intervals, or points in time.
Interval One
The power has just been applied to the server, but the front panel ON/OFF switch is OFF. The front
air intake fans will flash a dim red color, the bulk power supplies will flash amber and an amber
light is present on the hard disk drives.
Interval Two
After the power has been plugged into the server for about 30 seconds, the standby power turns
on and the front intake fan LED indicators turn solid green. The BPS will flash green and the amber
light is still present on the hard disk drives. The front panel ON/OFF switch is OFF at this interval.
Housekeeping power is up at this point.
Interval Three
With the ON/OFF switch on the front of the server set to ON, the intake fans spin up and become
noticeably audible, while the fan LED indicator remains solid green. The BPS LED indicator turns
a solid green, and the PCI backplane power supply LED indicators turn solid green. The hard disk
drive LED turns green briefly and then the LED turns OFF.
Installing The Line Cord Anchor (rack mounted servers)
The line cord anchor is attached to the rear of the server when rack mounted. It provides a method
to secure the line cords to the server preventing accidental removal of the cords from the server.
Four Cell Server Installation (rp8400, rp8420, rp8440, rx8620, rx8640)
There are holes pre-drilled, and captive nuts pre-installed, in the server chassis.
To install the line cord anchor
1. Align the line cord anchor thumbscrews with the corresponding captive nuts at the rear of the
chassis. See Figure 39: “Four Cell Line Cord Anchor (rp8400, rp8420, rp8440, rx8620,
