Section 3 — Kalypso Classic Frame

Emergency Bypass Frame

The 2 RU Emergency Bypass frame (

Figure 66

) fits a standard 19 in. (483

mm) equipment rack (See

Specifications on page 9

for dimensions). Behind

the front cover are ten slots for modules, plus one control slot and two slots
for power supplies. The standard Kalypso Emergency Bypass option only
uses two of these slots, typically slot 7 for the Relay Module and slot 8 for
the Keyer module.

The forced-air system has a front cover equipped with three fans for air cir-
culation. The fan speed varies with the ambient frame temperature. Fan
speed control voltage is generated on the Kalypso Emergency Bypass
Frame Monitor module and can be disabled so that the fan runs at
maximum speed only.

The right rear of the frame (

Figure 67

) includes ten groups of ten connectors

(corresponding to the ten frame slots), which are used for input/output
functions for inserted modules.

The power and 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 Kalypso Emergency Bypass Frame Monitor module is installed),
AC power plug connections, and SMPTE Alarm BNC (J101) for fault
reporting. The Ethernet connector is not used with the Kalypso Emergency
Bypass option.
