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.
requirements, you can add either one or two modules. A two-module system (7150
with 2 PoE-M PSU module) provides -54V, 15 A.
The GPLIM and PLIM 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.
