Removing a 7133 from a Rack
Notes:
|
1. This procedure applies only to Models 010 and 020.
2. You will need another service representative to help you remove the 7133 from the
rack.
Attention: Unless the using system needs to be turned off for some other reason, do not
turn off the using system when servicing the 7133. Power cables and external SSA
cables that connect the 7133 to the using system can be disconnected while that system
is running.
1
If this 7133 is connected to an operational SSA network, use the Link Verification
|
service aid (see the chapter about SSA service aids in the SSA Adapters: User’s
|
Guide and Maintenance Information manual) to ensure that all SSA loops that pass
through the internal strings of this 7133 are not broken. (For example, all external
SSA cables are connected correctly; all disk drive modules and, if required, dummy
disk drive modules are installed correctly.)
If a loop is broken, repair it before you start to remove the 7133 from the rack;
otherwise, the network might fail when you disconnect the 7133.
2
If not already done:
a. Ensure that all the disk drive modules in the 7133 are no longer available to the
using system.
|
b. Disconnect all the external SSA cables from the back of the 7133. To prevent
|
damage to the SSA connector screws, ensure that you use the special
|
screwdriver (SSA tool, part 32H7059) to unscrew them. The screwdriver is
|
supplied with the 7133.
c. Remove all power from the 7133 (see “All Power” on page 3-7).
|
d. Remove (if an early type) or open (if a late type) the front cover (see “Covers”
|
on page 3-2).

Note: For a translation of the following notice, see the Safety Information manual.
CAUTION:
The stabilizer must be correctly attached to the bottom front of the rack to
prevent the rack from tipping forward while the units are being removed
from the rack. Do not pull out or install any unit if the stabilizer is not
attached to the rack.
A 7133 weighs up to 50.0 kg (110 lb) with disk drive modules installed. Do
not attempt to remove the 7133 from the rack unless all the disk drive
modules have been removed.
|
You are now going to remove all the disk drive modules and (if present) dummy disk
|
drive modules from the 7133. If the 7133 is to be used later with its disk drive
|
modules configured as they are now, carefully make a note of the locations of the
|
disk drive modules and dummy disk drive modules before you start to remove them.
|
This action ensures that you reinstall the modules into their original slots. (They
|
might not all be connected to the same SSA loop.) Attach identifying labels to the
|
modules if you want to.
