Representatives
DANGER
To prevent a possible electrical shock from touching two surfaces with
different electrical grounds, use one hand, when possible, to connect or
disconnect signal cables. (RSFTD004)
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system or the products that attach to the system. It is the
customer’s responsibility to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock. (RSFTD201)
CAUTION:
Ensure that all rack-mounted units are fastened in the rack frame. Do not extend
or exchange any rack-mounted units when the stabilizer is not installed.
(RSFTC222)
CAUTION:
When the unit is extended, its weight can turn over a rack that is not steady.
Before you pull the unit out of the rack, ensure that a rack stabilizer is attached
to the bottom front of the rack.
Do not pull out more than one unit at a time. The rack can turn over if you pull
out more than one unit at a time. (RSFTC224)
Purpose of the MAPs
Maintenance analysis procedures (MAPs) are used to check the:
Power switch Power supply Power distribution cable
SAS cables DVD cable Fan
Configuration Drives VPD cable
Power cord Power source
The media drawer includes several LED’s that indicate the presence and source of
a fault, and has the capability to report faults to the operating system. These
should be the primary sources for fault identification. If these prove insufficient
then MAPs should be used, especially to identify faulty cables or cable
connections. If a problem is detected, the procedure isolates the problem to the
failing field replaceable unit (FRU).
For instructions about removing or replacing a FRU, refer to Chapter 3, “Removal
and Replacement Procedures,” on page 19
Note: Service actions involving the removal of the enclosure cover must be
performed by an IBM authorized service representative.
