Chapter 3 - Installation
SLTM2 Installation
The SLTM2 may be installed in any slot of the Main Cabinet, except for slot ten, or may be
installed anywhere in the Desk Mount Holder. The SLTM2 provides a gateway between
standard Single Line Telephone devices and the
Telenium
IP
system.
The basic SLTM2 can support two SLT devices and can be expanded with the SLTU2 by an
additional two SLT devices for a total of four devices. If required, install the optional
SLTU2 port expansion unit before installing or wiring the SLTM2, refer to
“SLTU2
Installation” on page 3-25
.
LEDs
In addition to the Power and LAN LEDs, the SLTM2 has eight status LEDs, two for each
respective SLT port 1-4. The left bank of four LEDs indicates the status of the associated
SLT port: in-use (LED on), ringing (LED flashing), or idle (LED off). The right bank of four
LEDs indicates Message Wait status for the associated SLT port; message active, LED on.
Wiring Connectors
Before wiring any of the Modules, first connect the "GND" screw on the back of the
Module to a known earth ground, refer to
“Module Grounding” on page 3-14.
On the front of the SLTM2 is the RJ 45 type "LAN" connector. This connector should be
wired to the appropriate LAN points as discussed in
“LAN Connections” on page 3-15 and “LAN
Wiring Structures” on page 3-16
.
 Wire "LAN" to a 10/100 Base-T switch. A SHUB8 can be used to form the Telenium
IP
Zone.
 Tag or number wiring for maintenance.
On the rear are four RJ-11 connectors which should be wired to the SLT termination
point. When using a Main Cabinet, refer to
“Main Cabinet Wiring” on page 3-29 for wiring
instructions.
 Wire each RJ-11 to an SLT device/MDF.
 Tag or number wiring for maintenance.
AC/DC Adapter
Assure the AC/DC Adapter is plugged into a live AC outlet and the Module Power jack.
The LEDs for circuits 3 and 4 function only when the SLTU2 is installed.
CAUTION: Before connecting the LAN from SHUB8, the appropriate switch
for DTE power must be in the "OFF" position.
