CAUTION
The Emergency Bypass frame front panel must remain in place during system
operation to provide proper cooling. If the panel is removed for an extended
period, modules can overheat and fail to operate correctly.
The forced-air system has a front cover that is equipped with three fans for
air circulation. The fan speed varies with the ambient frame temperature to
extend fan life and reduce noise when the frame is used in cooler configu-
rations and environments. The fan speed control voltage is generated on
the Bypass Frame Monitor module and can be disabled so that the fan runs
at maximum speed only (see
page 24
).
The right rear of the frame (
Figure 3
) includes ten groups of ten connectors
(corresponding to the ten frame slots), which are used for input/output
functions for inserted modules. The standard Kalypso Emergency Bypass
option only uses two of these groups, typically slot 7 for the Relay Module
and slot 8 for the Keyer module.
Figure 3. 8900TF Frame, Rear View
The power/communication section at the left rear of the frame provides:
•
RS-422 communications (the connector is labeled RS-232, but is RS-422
when the Bypass Frame Monitor module is installed),
•
AC power plug connections, and
•
SMPTE Alarm BNC (J101) for fault reporting (see below).
The Ethernet connector is not used with the Kalypso Emergency Bypass
option.
