Figure 7: BTI7801 Chassis Rear View
To provide front access to management ports and chassis alarm indicators, the BTI7801
cooling module is fitted with management ports and chassis status LEDs. For the
management ports to be operational, the 1-Slot Chassis Front Cooling Module (FAN5)
must be deployed with the optional Ethernet and Serial Link (ESL) module. The ESL
module extends management connectivity from the rear of the chassis to the front. It
connects to the FAN5 module from the rear and connects to the CMM using external
cables.
The LEDs provide a visual indication of the chassis alarm status and do not require the
ESL module.
