ED-64M Director Operating Features
◆
A 9-pin maintenance port that provides a connection for a local
terminal or dial-in connection for a remote terminal.
Although the port is typically used by authorized maintenance
personnel, and for operations personnel to set IP 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 Modules
Two fan modules, each containing three fans (six fans total), provide
cooling for director FRUs, as well as redundancy for continued
operation if a fan fails.
A fan module can be replaced while the director is powered on and
operating,
SBAR Card
Each SBAR card is responsible for Fibre Channel frame transmission
from any director port to any other director port. Connections are
established without software intervention. The card 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 card also stores busy, source connection, and error
status for each director port.
A backup SBAR card takes over operation if the active card fails. It
provides the ability to maintain connectivity and data frame
transmission without interruption if the active SBAR card fails.
Failover to the backup card is transparent to attached devices.
The SBAR card mounts flush on the backplane, and the SBAR FRU is
comprised of the card and a steel carriage. The carriage provides
protection for the back of the card, distributes cooling airflow, and
assists in aligning the card during installation. The carriage contains
two LEDs to indicate operational status. For details on LED
operation, refer to SBAR Cards on page 2-9.
Backplane
The backplane provides 48 VDC power distribution and connections
for all logic cards. The backplane is a nonconcurrent FRU; the director
must be powered off prior to FRU removal and replacement.
