9. Repeat all of these steps to install additional 2145 UPS-1Us.
Installing the 2145 UPS
Before you can use the SAN Volume Controller 2145-4F2, you need to install the
uninterruptible power supply (UPS).
The SAN Volume Controller 2145-4F2 node can operate with either the 2145 UPS
or the 2145 UPS-1U. For more information about installing the 2145 UPS-1U, see
“Installing the 2145 UPS-1U” on page 80 and then “Connecting the SAN Volume
Controller 2145-4F2 to the 2145 UPS-1U” on page 133.
Complete the following steps to install the 2145 UPS:
1. Install the support rails for the 2145 UPS.
2. Install the 2145 UPS into the rack.
3. Connect the 2145 UPS battery.
4. Connect the power cables to the 2145 UPS.
Installing the support rails for a 2145 UPS
You must install the support rails in the rack before installing the 2145
uninterruptible power supply (2145 UPS).
Before you install the support rails, determine where the 2145 UPSs are to be
installed in the rack. Complete the following prerequisites before you install the
support rails:
v Use the user’s hardware location chart, which you downloaded from
http://www.ibm.com/storage/support/2145, to determine where in the rack
that you want to install the 2145 UPS.
v Discard the two handles and their associated nuts that are shipped with the
support rails.
v 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 UPS. 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:
1. Attach nut clips
4
to the rack (see Figure 83 on page 122). These nut clips
must align with the second and fourth holes of the support rail flange.
