3.3.16 GSIM (Gigabit Switch Interface Module)
The GSIM is a managed Layer 3 LAN switch. It offers ten (10) 1000 Base-SX/LX/TX interface
ports and one SIO port.
SPECIFICATIONS
The GSIM can be installed in any universal slot in any OS7400 cabinet.
Do NOT install the GSIM in an OS7200 expansion cabinet.
A maximum of 2 GSIMs can be installed per cabinet. Maximum 6 GSIMs per system can be
installed.
Refer to the GSIM Users Manual for further configuration and installation details.
Determine whether or not the GSIM will use the internal OS7400 power supply or the optional
external OfficeServ 7150 PoE PSU.
Refer to the OfficeServ 7150 section in this manual to
Set J3 and J4 of the GSIM module accordingly.
To force the GSIM/GSIMT to get power from the external OfficeServ 7150 PoE unit, you must
connect shunt pins 2 and 3 for each jumper J3 and J4. Shunt pins 1 and 2 are connected at
factory default. (This setting causes the PLIM to get power from the internal OS7400 power
supply.)
