Installing a Two-Port Loop Start Module (LSM-2)
Install the two-port loop start module (LSM-2) as described below. Part numbers appear in Table 59,
“Replacement Parts,” on page 372 . See Figure 4 on
page 189
.
To install the two-port Loop Start module (LSM-2):
1. Using a properly terminated, anti-static wrist strap, remove the module from the protective
anti-static bag.
2. Insert the module carefully so that it aligns with the rails inside the chassis, then gently slide the
module into the chassis until it stops and the module release lever clicks into place (up position).
Do not use force.
3. Tighten the fastener at the top of the module, securing it to the chassis. Do not over tighten this
fastener.
4. If not adding any other modules, continue to “Installing the USB Security Key and Compact
Flash-Type Memory Card” on page 150. Otherwise, continue to “Installing a Single-Port
T1/E1/PRI Module (T1M)” on page 194.
To remove the two-port Loop Start module (LSM-2):
1. Using a properly terminated, anti-static wrist strap, loosen the fastener at the top of the module.
This fastener secures the module to the chassis.
2. Push down and hold the module release lever.
3. When the
REMOVE
LED turns green, grasp the module handle and carefully remove the module
from the chassis.
IMPORTANT
The loop start module can be removed with power on; however, you must wait for
the REMOVE LED indicator to change to green before removing the module.
Pressing and holding the release lever down until the LED indicator turns green
allows the software to “disconnect” from the module. Failure to wait until the LED
turns green, could result in pending information getting lost or unexpected system
behavior.
Other than the PM-1, all other modules can reside in any bay. However, DB Pro
-
gramming will need to change, if you move a module (that was previously pro -
grammed) into a different bay location.
