Installing a Field Expansion Rectifier Shelf
DANGER!
Adhere to the “Important Safety Instructions” presented at the front of this document.
NOTE!
Refer to
Figure 1
and
Figure 2
as this procedure is performed.
Procedure
1. Remove the rear shield from the main module mounting assembly. This shield will not be re-used.
2. When the main module mounting assembly is configured with the front AC option, replace the mounting
angle on the left side (as viewed from the front) of the expansion module mounting assembly with the
longer mounting angle shipped loose with the expansion module mounting assembly.
3. Install the expansion module mounting assembly directly below the main module mounting assembly.
Use the mounting hardware provided with the expansion module mounting assembly. See
Figure 1
.
Refer also to Figure 1 for hardware build-up and recommended torque.
NOTE!
Install (orient) the ground washers so the teeth dig into the mounting angles for a secure
ground connection.
NOTE!
Compliance with Telcordia GR-1089-CORE requires that prior to mounting the system to the
equipment rack:
•
All paint must be removed from the front surface of each equipment rack rail where it mates with a
shelf-mounting bracket, so that good metal-to-metal contact can be established between the shelf
and rack.
•
The shelf-to-rack mating surfaces must be cleaned.
•
Electrical anti-oxidizing compound must be applied to the shelf-to-rack mating surfaces.
4. Remove the rear shield from the expansion module mounting assembly.
NOTE!
Apply electrical anti-oxidizing compound to busbar mating surfaces before performing the next
step.
5. Remove the hardware from the main module mounting assembly’s -48V and return busbars.
6. Loosen the hardware from the expansion module mounting assembly’s -48V and return busbars.
7. Slide the busbars provided with the expansion module mounting assembly into position. These busbars
are installed between the busbar studs on the expansion module mounting assembly and the busbar
studs on the main module mounting assembly. Secure these busbars to the expansion module
mounting assembly with the hardware provided with the expansion module mounting assembly. Secure
these busbars to the main module mounting assembly with the hardware provided with the main module
mounting assembly. Refer to
Figure 1
for hardware build-up and torque.
8. Disconnect the cable coming from the distribution unit that is connected to the left side (as viewed from
the rear) connector on the main module mounting assembly. Connect this cable to the left side (as
viewed from the rear) connector on the expansion module mounting assembly. See
Figure 2
.
