5.3 CONNECTING THE OFFICESERV 7150 EXTERNAL PoE
PSU SUPPLEMENTAL POWER SUPPLY
The OfficeServ 7150 PoE PSU provides additional power to your OfficeServ 7400 cabinets
when the internal OfficeServ 7400 PSU limits have been exceeded by PoE devices connected
to the PLIM or GPLIM modules. When installing a PLIM, GPLIM, GSIM or GWIM, you can seIect
whether these modules use the internal OS7400 power supply or the OS7150 external PoE
PSU by setting the internal jumpers accordingly.
The OS7150 is composed of a cabinet which can accomodate up to two POE-M Power supply
modules. Each module provides -54V, 7.5A. Depending on your power requirements, you
can add either one or two modules. A two-module system (7150 with 2 PoE-M PSU module)
provides -54V, 15A.
The GPLIM and PLIM/PLIM2 module uses the -48V rail from the OfficeServ 7400 power supply
to provide power to the connected devices over ethernet. The OfficeServ 7400 power supply
provides up to 6600mA of output current.
PER EACH OS7400 CABINET (not per system), the SUM of all current drawn from 1)
devices powered by PLIM cards, 2) digital key sets connected to DLI ports 3) analog
devices connected to SLI ports 4) devices powered by the GPLIMs 5) the GWIM/GWIMT,
GSIM/GSIMT and GPLIM/GPLIMT cards themselves cannot exceed 6600mA. The chart
below provides current ratings for various devices connected to the system:
