You must install the support rails in the rack before installing the 2145 UPS.
Before you install
the support rails, determine where the 2145 UPS units
are to be installed in the rack. Complete the following prerequisites
before
you install the support rails:
- Use the user's hardware location chart, which you downloaded from www.ibm.com/storage/support/2145, to determine where in the rack that you want to install the 2145 UPS.
- Discard the two handles and their associated nuts that are shipped with the support rails.
- At the back of the rack, observe the Electronic Industries Alliance (EIA) positions and determine where you are going to install the 2145 UPS. Always install the 2145 UPS into the lowest available position in the rack. The only device that can be beneath a 2145 UPS is another uninterruptible power supply. The bottom of the flange of the support rail must align with the EIA mark on the rack.
Note: The user can already have installed in
the rack a 2145 UPS with
available spare capacity. Therefore, the SAN
Volume Controller 2145-4F2 might
be delivered without a 2145 UPS.
Perform the following steps for each rail:
- Attach nut clips
to the rack (see Figure 1).
These nut clips must align with the second and fourth holes of the
support
rail flange.
- Loosen the two wing nuts
. - Loosen
the wing nut
and slide the bracket toward the back
of the
rail. - Remain at the back of the
rack holding the support
rail in position in the rack, and then install and fully tighten the
two mounting
screws
. - Install the two mounting
screws
into the third and fourth holes
of the support rail flange. Fully tighten the screws. - Fully tighten the two wing nuts .
- Loosen
the wing nut and slide the bracket toward the front
of the
rail as far as it will go, with the front edge of the bracket against
the
back-end of the front support rail.
- Fully tighten
the wing nut . Note: You must perform all of the previous steps for each rail.
