OfficeServ 7400 INSTALLATION
TECHNICAL MANUAL PART 3 JUNE 2006
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 GPLIM's 5)the GWIM, GSIM and GPLIM cards
themselves cannot exceed 6600mA . Refer to the OfficeServ 7150 section in this
manual for a listing of individual component current draw ratings.
IF ADDING PLIM CONNECTED DEVICES CAUSES THE TOTAL CURRENT DRAWN TO
EXCEED 6600mA PER CABINET (not per system), THEN YOU MUST CONNECT THE
OS 7150 EXTERNAL PoE POWER SUPPLY MODULE to the cabinet. This unit can
provide additional power to PoE devices connected to PLIM's and GPLIM's when the
OS7400 power supply limits have been exceeded. Please refer to section 5.3,
CONNECTING THE OS 7150 EXTERNAL PoE PSU SUPPLEMENTAL POWER SUPPLY
for further information.
It is important to note that the OS 7150 can only provide additional power to the PLIM,
GPLIM, GWIM and GSIM. The OS 7150 is used when the GSIM, GWIM or PoE devices
connected to GPLIM/PLIM causes the total current draw per cabinet to exceed
6600mA. It does not provide power to DLI ports, MWSLI ports and other system
interface cards.
To force the PLIM to get power from the external OfficeServ 7150 PoE unit, you must
connect shunt pins 2 and 3 for each jumper J1, J2, and J3. Shunt pins 1 and 2 are
connected at factory default (this setting causes the PLIM to get power from the internal
OS7400 power supply).
