Installing the Caller ID Option Module
The Caller ID Option Module is installed inside a Port Expansion Unit Model 200 (PV-PEU-200) or
Port Expansion Unit Model 205 (PV-PEU-205), serial number 40,000 and above. The Caller ID
module is not used with the Port Expansion Unit Model 250 (PV-PEU-250) as it contains integrated
Caller ID circuitry on all 16 ports. If you want to set up Caller ID on CO lines connected to
additional PEUs, you must install additional Caller ID Option Modules in those PEUs.
To install the Caller ID Option Module inside a PEU, complete the following steps:
Warning! Before installing the Caller ID Option Module, first touch the metal case of the PEU to
discharge any static electricity. Static electricity can damage the Caller ID Option Module
and your system.
1. Disconnect the CO lines from the PEU, and then turn off the system. Unplug the PEU and
remove its cover.
2. Find the two male standoffs in the PEU. They are located on either side of the 50-pin connector.
Male Standoffs
in the PEU
Note Some PEUs have female standoffs instead of male standoffs. To install the Caller ID
Option Module on a PEU with female standoffs, place the holes on the Module over the
female standoffs on the PEU. Use the two screws provided, and place them into the holes
to secure the Caller ID Option Module. If the Module is not properly installed, the holes do
not align and the screws do not fit.
3. Install the Caller ID Option Module with the component side facing down. Align the two holes
on the Module with the male standoffs.
4. Use the two nuts provided, and fasten them onto the standoffs to secure the Caller ID Option
Module. If the Module is not properly installed, the holes do not align, and the nuts do not fit on
the standoffs.
