Installing a Basic Rate Module (BRM-2)
The Basic Rate Module (BRM-2) is used for connecting ISDN S-interface trunking. For additional
information about modules, see the Specifications and Product Description chapters.
To install a BRM-2:
1. Using a properly terminated, anti-static wrist strap, remove the module from the protective
anti-static bag. See
Figure 10
for an example of the BRM-2 module for the remaining steps in
this procedure.
2. If applicable, remove any protective covers over the module bay where you want to install the
BRM-2. These covers prevent debris or other foreign matter from entering the system and
possibly harming the internal components. These covers should remain in place until you are
ready to install a module.
3. Insert the BRM-2 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.
4. Tighten the fastener at the top of the module, securing it to the chassis. Do not over tighten this
fastener.
5. Continue to “Verifying and Securing Cable Connections” on page 165.
To remove a BRM-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, then when the REMOVE LED turns green, grasp
the module handle and carefully remove the module from the chassis.
IMPORTANT
The BRM-2 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 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.
BRM-2 modules can reside in any expansion bay. However, DB Programming will
need to be changed if you move a module that was previously programmed into
a different bay location.
