3.3.13 PLIM (PoE LAN INTERFACE MODULE)
The PLIM sends/receives data to/from the internal LAN, and provides 16 ports of 10/100 Base-
T Ethernet interfaces. It functions as a Layer 2 LAN switch. The PLIM can connect with the WIM
through the internal back panel if it is in slot 2 and the WIM is in slot 1 with appropriate
jumper settings. 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/SMT-i phones and SMT-R2000 Dual-Band APs can receive power when
connected to PLIM. When connected to the PLIM Ethernet port, these devices no longer need
the AC power adapter.
The PLIM can be installed in slots 2 through 5 of any cabinet. However, for the PLIM to be a
managed switch, it must be installed in slot 2 with a WIM in slot 1. A maximum of 8
PLIM/PLIM2s can be added however only one PLIM per system can be a "managed" switch.
When a PLIM acts as an unmanaged switch, it simply performs as a simple data switch (10/100
Base-T). When it is managed (by WIM), advanced features such as Layer 2 QoS, 802.1q (VLAN),
IGMP snooping, and much more are available. For it to be managed by the WIM, it must be
