Card Maintenance/Replacement
This section defines the proper procedure for making changes to the card configuration of your Tenor CMS
chassis.
When the WAN card (Front Application card) is inserted in a slot, it connects to an associated Rear Transition
Module (RTM) in the rear of chassis. The transition module is inserted into the rear of the chassis and corre-
sponds to the card in the front slot; it provides the physical cabling and external interface connections. Not all
cards contain Front Application and RTM cards. Front Application cards measure 160mm x 233mm and Rear
Transition Module / Interface Cards measure 80mm x 233mm, (half the size of the Front Application Cards).
See below for a description of each cards’s overlay label, whether a Rear Transition Module is required, along
with slot installation and special instructions.
CAUTION: Mixing of Front Application and Rear Transition Module (RTM) card types, may cause dam-
age to the cards and the chassis and may void your warranty.
