3.3.11 PLIM (PoE LAN INTERFACE MODULE)
The PLIM board sends/receives data from the internal LAN, and provides an interface
of 10/100 BASE-T. It functions as a layer 2 LAN switch. The PLIM supports Power over
Ethernet (IEEE 802.3af). This means that it can provide power to any IEEE 802.3af
compliant device that is connected to any of its Ethernet ports. All Samsung ITP
phones and SMT-R2000 Dual-Band AP's can receive power when connected to the
PLIM. When connected to the PLIM Ethernet port, these devices no longer need the AC
power adapter.
The PLIM can be installed in any universal slot of any cabinet. Add as many PLIM's as
needed.
The PLIM is an unmanaged switch, so it simply functions as a simple data switch
(10/100 BASE-T).
PLEASE NOTE: The PLIM module uses the -48V rail from the OS7400 power supply to
provide power to connected devices over Ethernet. The OS7400 power supply
