Chapter 4 Troubleshooting 51
Customer Replaceable Units
The following FRUs enable you to deal with faults:
■
Hard drives – hot swappable
■
PSUs (PS0/PS1/PS2/PS3) – hot-swappable
Note – Only suitably trained personnel or Sun Service are permitted to enter the
Restricted Access Location to hot-swap PSUs or hard drives.
■
CPU/memory boards (SB0/SB2/SB4) – can be blacklisted if considered faulty
■
Repeater boards (RP0/RP2) – can be blacklisted if considered faulty
If a fault is indicated on any other FRU or a physical replacement of blacklisted
FRUs above is required, then Sun Service should be called.
Disabling Components on a Board
The SC supports the blacklisting feature, which enables you to disable components
on a board (
TABLE 4-5
).
Blacklisting provides a list of system board components that will not be tested and
will not be configured into the Solaris Operating System. The blacklist is stored in
nonvolatile memory.
Blacklisting a component, requires providing a blacklisted name. The blacklisted
name is derived from the system and subsystem to which the component belongs.
For CPU systems, the blacklist name is of this form:
Main fan Yes Yes No
Media bay No Yes Yes
Disk Yes Yes No
* This includes faults where the FRU is only degraded.
1 If lit, indicates the failing FRU is accessed from the top of the platform. It is important that you employ the antitilt legs on the cabinet
before extending the platform out on its rails.
