3.3.1.5 PLIM Module
The LAN Interface Module with PoE (PLIM) can use the Power Supply Unit (PSU) or an
external rectifier by selecting the power source using jumpers.
To use the PSU: jumpers J1, J2 and J3 are connected between pin1 and pin2.
Since the capacity of the PSU is limited, the number of ports is limited to 16 and the
use of digital phones is also limited. (For more information on these limitations, con-
tact your dealer.)
To use an external rectifier: jumpers J1, J2 and J3 are connected between pin2 and
pin3. Since the external rectifier can supply 10A current per module, there is no limita-
tion on the use of ports or digital phones.
Limit the current running through the PLIM ports to below 0.1A , and in the module to
below 1.6 A.
Each jumper is numbered in ascending order from that marked '1' in the following figure.
Pin No.
