3.2 Frequently asked questions
Why are no LEDs illuminated?
Check that at least one frame PSU is functioning
Check that the frame is powered and that the fuse is intact
What should I do if the TEMP LED is red and/or the FRAME TOO HOT message is
displayed?
Check that cool air is able to circulate through the front panel grilles and out of the ventilation
holes at each side of the frame
Check that the panel and PSU fans are operational and that the FRONT FAN and PSU FAN
LEDs are not red
What should I do if the PSU FAN LED is red?
Check that the PSU fan is plugged in correctly
Try replacing the fan
What should I do if the FRONT FAN LED is red?
Check that the front control panel fan is plugged in correctly
Try replacing the fan
What should I do if any PSU LED is red?
Try replacing the appropriate PSU
Why do I keep getting a warning message about a power supply problem? (REMIND)
If PSU warnings persist even when no PSU fault is suspected, check that the Two/One PSU
switch at the rear of the front panel is set correctly for the number of power supplies installed
Why does the LOWER PSU LED flash from green to off?
This will occur if the third PSU is fitted when the Two/One PSU switch at the rear of the front
panel is set for only one PSU. Move the switch into the Two position.
Why do some cards not appear in the available cards list? (REMIND)
Some cards take longer than others to finish their initialisation routines - try waiting at least
30 seconds for all cards to initialise
Check that any cards with remote/local switches are set for remote control
Check that any hex node switches are set to zero
How do I check PSU or RS422 comms status?
Press the Device key in Statesman mode to display frame diagnostics
Look at the Comms LED. It should flash slowly at medium intensity when a valid
communication link is present. It will flash brightly when the communication link is active
