Installing a Four-Port Loop Start Module (LSM-4)
The LSM-4 provides four trunk interface ports. For additional technical data about the LSM-4, see
the Specifications chapter. See page 154 for information on how this module is cabled to the MDF.
To install an LSM-4:
1. Using a properly terminated, anti-static wrist strap, remove the module from the protective
anti-static bag. For an example of an LSM-4 module that you can see for the remaining steps
in this procedure, see
Figure 5
.
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. Do not use force.
3. Tighten the fastener at the top of the module, securing the module to the chassis. Do not over
tighten this fastener.
4. Continue to “Verifying and Securing Cable Connections” on page 165.
To remove an LSM-4:
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 LSM-4 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 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.
LSM-4 modules can reside in any bay. However, DB Programming will need to change,
if you move a module (that was previously programmed) into a different bay location.
