Equipment shipped assembled
The low -capacity , +27 V DC UBS Macro BTS is shipped pre -assembled on carrier strips with
all internal cabling installed. This pre -assembled equipment is delivered in a crate. A fter the
crate is unpacked, the low -capacity +27 V DC UBS Macro BTS assembly is ready to be rack
mounted. The carrier strips allow up to four people to carefully lift the assembly off the crate
packing onto the rack. The assembly can also be lifted via some mechanical aid (hoist, etc.)
attached to the lifting loops on the ends of the carrier strips. The carrier strips also provide easy
rack mounting. A fter the UBS Macro equipment is rack mounted, cables are connected between
the UBS Macro equipment and external site inputs/outputs.
Equipment shipped un -assembled
The low -to -mid capacity expansion equipment and associated cables are shipped in separate
individual containers. The additional expansion equipment is mounted into the low -capacity
frame and then the associated interconnect cables are installed.
F or -48 V DC or 220 V AC UBS Macro BTS applications, either a -48 V DC or AC PSM (P ower
Supply Module) shelf is required. The PSM shelf comes assembled, but without PSMs installed
in the shelf . Either up to two -48 V DC or up to two AC PSMs can be installed in the shelf . One
PSM is required for the low capacity configuration and the second PSM is for redundancy . The
PSM shelf without PSMs is delivered in a single box. Each PSM is delivered in a single box. The
PSM shelf is mounted at the bottom of the rack. Then the PSMs are installed in the PSM shelf .
The +27 V DC UBS Macro assembly is mounted just above the PSM shelf . The PSM +27 V DC
output cable is connected to the +27 V DC input cable on the +27 V DC UBS Macro assembly .
The site -48 V DC or 220 V AC power source is cabled/wired to the PSM shelf .
The Remote GPS (RGPS) head and associated cable are shipped un -assembled. The cable has to
be connected to the RGPS head along with the customer supplied mounting mast.
Most of the cable/wire connectors that are required to connect with the UBS Macro equipment
external site input/output connectors are supplied, but need to be assembled onto cables/wires.
Most of the cables/wires are supplied by the customer .
