Chapter 4. Dealing with Problems
This chapter describes what to do if you have a problem with a 7133 Model D40 or
T40, how to change a faulty disk drive module, fan assembly, or power-supply
assembly, and what information to provide when you report a problem with a 7133
Model D40 or T40 or a device installed in it.
Starting to Deal with Problems
How to start dealing with SSA problems depends on the system to which your 7133 unit
is attached. “Appendix A. Operating with RISC Systems” on page 71 describes what to
do if you are using RISC based systems. “Appendix B. Operating with PC Servers” on
page 85 describes what to do if you are using PC Servers.
Additional problem indications
If the 7133 check light is on, look at the four character display. This may be displaying
an Error ID alternating with the 7133 ID. The Error ID may be one of the following:
SLOT The 7133 controller has detected one or more unpopulated drive positions. All
positions must be populated with either a disk drive or a dummy disk drive
module. If any slot is unpopulated, correct the situation. If all positions are
populated, report the problem to your service organization.
FAN1, FAN2, or FAN3
The 7133 controller has detected a defective fan. Replace the defective fan
(see “Changing Fan Assemblies” on page 49 for how to do this) or report the
problem to your service organization.
PSU1 or PSU2
The 7133 controller has detected a defective power supply unit. Replace the
defective power supply unit (see “Changing Power-Supply Assemblies” on
page 56 for how to do this) or report the problem to your service organization.
COLD, COOL, WARM, HOT
The 7133 controller has detected an ambient temperature problem. Take
actions to correct this condition. If you consider that the detection report is
wrong, report the problem to your service organization.
Any other error ID or no error ID
Report the problem to your service organization.
