General Information

• An RS-232 maintenance port at the rear of the director (port

access is password protected) that enables installation or service

personnel to change the director’s internet protocol (IP) address,

subnet mask, and gateway address; or to run diagnostics and

isolate system problems through a local or remote terminal.

The director parameters can also be changed through a Telnet

session, accessfor which is providedthrough a localor remote PC

with an Internet connection to the director.

• Data collection through the Element Manager application or the

EFCM Basic Edition interface to help isolate system problems.

The data includes a memory dump file and audit, hardware, and

engineering logs.

• Beaconing to assist service personnel in locating a specific port,

FRU, or director in a multiswitch environment. When port

beaconing is enabled, the amber LED associated with the port

flashes. When FRU beaconing is enabled, the amber (service

required) LED on the FRU flashes. When unit beaconing is

enabled, the system error indicator on the front bezel flashes.

Beaconing does not affect port, FRU, or director operation.

• An internal modem for use by support personnel to dial-in to the

management server for event notification and to perform remote

diagnostics.

• Automatic notification of significant system events (to support

personnel or administrators) through e-mail messages or the

call-home feature.

NOTE: Thecall-homefeatureisnotavailablethroughtheEFCMBasic

Edition interface. The call-home feature may not beavailable if the EFCM

Lite application is installed on a customer-supplied platform.

• Concurrent port maintenance. UPM and XPM cards are added or

replaced and fiber-optic cables are attached to ports without

interrupting other ports or director operation.

• Status monitoring of redundant FRUs and alternate Fibre

Channel data paths to ensure continued director availability in

case of failover. The SAN management application queries the

status of each backup FRU. A backup FRU failure is indicated by

an illuminated amber LED.
