Intrepid® 6064 Director Installation and Service Manual

General Information

Power Module

Assembly

The power module assembly is located at the bottom rear of the

director. The module is a nonconcurrent FRU, and the director must

be powered off prior to scheduled removal and replacement. The

module provides:

• Two single-phase AC power connectors. Each connector is input

rated at 85 to 264 VAC.

• A power switch (circuit breaker) that controls AC power

distribution to both power supplies. The breaker is set manually,

or isautomatically trippedby internal softwareif thermal sensors

indicate the director is overheated.

• A 9-pin maintenance port that provides a connection for a local

terminalordial-in connection fora remote terminal. Although the

port is typically used by maintenance personnel, operations

personnel use the port to configure network addresses.

• An input filter and AC system harness (internal to the FRU) that

provides the wiring to connect the AC power connectors to the

power switch and power supplies (through the backplane).

Fan Module

Two fan modules, each containing three fans (six fans total), provide

cooling for director FRUs, as well as redundancy for continued

operationifafanfails.

A fan module can be replaced while the director is powered on and

operating, provided the module is replaced within ten minutes (after

module illuminates if one or more fans fail or rotate at insufficient

angular velocity.

SBAR Assembly

The directoris delivered with twoSBAR assemblies. Theactive SBAR

isresponsibleforFibreChannelframetransmissionfromany director

port to any other director port. Connections are established without

software intervention. The assembly accepts a connection request

from a port, determines if a connection can be established, and

establishes the connection if the destination port is available. The

assembly also stores busy, source connection, and error status for

each director port.

The backup SBAR takes over operation if the active assembly fails,

and provides the ability to maintain connectivity and data frame
