Some messages appear briefly (millisecond duration), and others last several
seconds. If one of the messages appears frozen, the boot process could be hung.
Note the message being displayed on a piece of paper. Turn off the system power
supply power switches, then turn them back on to reset the system and start the boot
process anew. If the system hangs again, the RP could be faulty and in need of
replacement.
Table5-2 RP Alphanumeric Display Messages
•If the power supplies and fan trays are operational, but none of the RP LEDs or displays
are on, the RP might not be properly installed, or the +5.2 VDC output from the power
supply(ies) might be faulty. Turn the rotary power supply switch(es) off, and then loosen
the two captive screws at the top and bottom of the RP faceplate; use the ejector levers
on the RP to eject it and reseat it. Tighten the two captive screws, and power up the
system by turning the rotary power switch(es) to the on (|) position.
