Operating the Director
Fan Modules Each fan module has one amber LED. The LED illuminates when a
fan fails or is rotating insufficiently. Refer to Figure 2-2 for LED
locations.
SBAR Cards As seen from the rear of the director, the SBAR card carriage contains
a green LED and amber LED indicator. The green LED illuminates if
the card is operational and is the active card, and the amber LED
illuminates if the card fails. Both LEDs are dark on an operational
backup card. The amber LED blinks if FRU beaconing is enabled.
Refer to Figure 2-2 for LED locations.
Input Power Module The input power module is located at the bottom rear of the director.
The module includes two AC power connectors, maintenance port,
and a power on/off switch.
AC Power Connectors Two single-phase AC power connectors. Each connector is input
rated up to 264 VAC.
Power On/Off Switch The power switch (circuit breaker) controls AC power distribution to
both power supplies. The breaker is set manually or is automatically
tripped by internal software if thermal sensors indicate the director is
overheated.
Maintenance Port The maintenance port provides a 9-pin DSUB connection for a local
terminal or dial-in connection for a remote terminal. Although the
port is typically used by authorized maintenance personnel,
operations personnel can use the port to set IP addresses.
