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 5-23 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 5-19 .
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 5-33 .
Figure 5-19. LSM-4 Module
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.
NOTICE
Electrostatic Discharge (ESD) . The modules and components are static-sensitive. When
working with the modules, use a properly terminated anti-static wrist strap. Any static charge
(no matter how small) must be discharged from the body before touching the modules or
other components. The warranty for this equipment does not cover damage caused by static
or mishandling. Modules or components damaged in such a manner will
not be replaced.
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.
