You must install the support rails in the rack before installing the 2145 UPS-1U.
Complete the following prerequisites before installing the
support rails:
- Use the customer's hardware-location chart to determine where in the rack that the 2145 UPS-1U is to be installed.
- At the back of the rack, observe the Electronic Industries Alliance (EIA) positions and determine where you are going to install the 2145 UPS-1U. Because of its weight, position the 2145 UPS-1U where it is easy to handle in one of the lower positions in the rack.
Perform the following steps to install the support rails
for the 2145 UPS-1U:
- Attach the long side of a mounting bracket 1 to each side of the 2145 UPS-1U using four M3 × 6 screws 2 for each bracket, as shown in Figure 1.
- Loosen the assembly wing nuts ( 1 in Figure 2) on both rail
assemblies and adjust the rail size to the depth of your rack. After
you adjust the depth, tighten the assembly wing nuts as much as possible
while still allowing some movement.
- 1 Assembly wing nuts
- 2 Wing nut
- Using two M6 × 10 screws ( 1 in Figure 3) and two clip nuts 2 , attach the rail to the rear of the rack. The customer's rack might be different than the one shown here, and if so, might require different clip nuts or fasteners.
- Install two clip nuts ( 2 and 3 in Figure 4) to the front of the rack, then attach the rail using just one M6 x 10 screw in the bottom mounting hole 1 .
