CPX8216 and CPX8216T Installation and Use (6806800A52C)
Chapter 3 Platform Description
22
Alarm Display Panel
The alarm display panel provides the chassis LEDs and remote alarm functions for the
CPX8216 and the CPX8216T. It is powered and controlled from each of the two Hot Swap
Controllers within the chassis (see Figure 3-7).
In order to provide a uniform appearance, without depending on individual board
manufacturers, the CPX8216 contains a separate alarm display panel, which runs across the
top of the chassis. In addition to In Service/Out of Service LED indicators for all sixteen slots,
the alarm display panel contains LEDs for system status (System in Service/Component out of
Service/System out of Service) and for the three standard Telco levels (Critical/Major/Minor).
The three Telco alarms are also signalled through a dry contact relay.
The alarm display panel features three system status LEDs, three Telco alarm status LEDs,
three slot status LEDs for each slot, and an RJ-45 connector for Telco alarm status output to an
external interface (see the following figure). Normally, only two of the three slot status LEDs are
visible—the third is covered by the panel’s overlay.
