16 Getting Started with the McDATA Intrepid FICON Director
The backup CTP card takes over operation if the active card fails. Failover from a faulty card
to the backup card is transparent to attached devices.
Each card faceplate contains a green LED that illuminates if the card is operational and
active, and an amber LED that illuminates if the card fails. Both LEDs are extinguished on an
operational backup card. The amber LED blinks if FRU beaconing is enabled.
Power supply
Redundant, load-sharing power supplies step down and rectify input power to provide 48-volt
direct current (DC) power to Director FRUs. The power supplies also provide overvoltage and
overcurrent protection. Either power supply can be replaced while the Director is powered on
and operational.
Each power supply has a separate backplane connection to allow for different AC power
sources. The power supplies are input rated at 85 to 264 volts alternating current (VAC). The
faceplate of each power supply provides the following status LEDs:
򐂰 A green PWR OK LED illuminates if the power supply is operational and receiving AC
power
򐂰 An amber FAULT LED illuminates if the power supply fails
򐂰 An amber TEMP LED illuminates if the power supply shuts down due to an over
temperature condition
򐂰 An amber I LIM LED illuminates if the power supply is overloaded and operating at the
current limit which is 15.6 amperes.
RFI shield
The RFI shield covers and provides RFI protection for all rear-access FRUs, except the power
module assembly. The RFI shield is concurrent and can be removed or replaced while the
Director is powered on and operating.
Power Module Assembly
The power supply assembly is located at the bottom rear of the Director.
The module provides the following:
򐂰 Two single-phase AC power connectors. Each connector’s input rated is 85 to 264 VAC.
򐂰 A power switch (circuit breaker) that 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.
򐂰 A 9-pin maintenance port that provides a connection for a local terminal or dial-in
connection for a remote terminal. The port is used by maintenance personnel to configure
network addresses
򐂰 An input filter and AC system harness (internal to the FRU) that provides the wiring to
connect AC power connectors to the power switch and power supplies (through the
backplane).
Note: Director firmware is upgraded concurrently (without disrupting operation).
Important: The module is a non-concurrent FRU and the Director must be powered off
prior to removal or replacement.
