Chapter 2 Installation
2.5 Electrical Installation
With an AC power model, AC power is supplied to the IPM-4SE through a standard IEC C14 3-prong receptacle,
located on the rear of the unit. Any national power cord with IEC C13 line plug may be used to connect AC power to
the power module. With a DC model, DC -48V is connected to the terminal block located on the rear of the module,
observing the proper polarity. The IPM-4SE should always be grounded through the protective earth lead of the power
cable in AC installations, or via the frame ground connection for DC installations.

2.6 Rack Installation
There are 3 common parts for each IPM-4SE package, including 1 set of TDM over IP multiplexer, 1 AC
power cord. If the IPM-4SE is intended for mounting into a rack, a pair of L-type Steel brackets with 16
screws should be requested with the user's order. The user manual, an electronic PDF format file, will be
included on a CD-ROM along with any accessory files such as SNMP MIB files and example script files.
The following Figure 2.3 shows desktop or shelf operation and Figure 2.4 shows rack mounting of the IPM-
4SE.
