5. INSTALLATION
This section provides information for installing an 86431 Power Unit. All
JungleMUX nodes are shipped with Power Units installed as per the Node
Assignment Drawing for the node. The Power Unit does not have any
configurable parameters and therefore no software programming is required.
CAUTION
The 86431 Power Unit has ESDS components and therefore standard static
protection
precautions should be observed when handling, packing or
shipping the unit.
Pre-installation
Visually check the unit for damage. Ensure that the jumper P2 (applicable to
B86431-4X units) is in Normal position and the screws are in place and firmly
tightened. Keep the shipping containers and packing materials for future use. If
a unit is damaged, file a claim with the shipping agent or the local GE Multilin
representative.
Shelf Position
The Power Units are normally installed in both the 1st and 15th shelf slots of
each JungleMUX shelf. Power Units are paralleled so in the event of single unit
failure the shelf power is maintained. If necessary, an additional (third) Power
Unit can be installed in the shelf. The power buses of multiple shelves belonging
to the same JungleMUX node can be paralleled (refer to the 86430 Equipment
Shelf TPIM). It is recommended that no more than six Power Units be
paralleled.
A typical rack layout is shown in Figure 5.
