• Directors and fabric switches provide an internal modem for use
by support personnel to dial in to the management server for
event notification and to perform remote diagnostics.
NOTE: SAN routers do not provide modem support.
• An RS-232 maintenance port on the director, fabric switch, or
SAN router (port access is password protected) that enables
installation or service personnel to change the product's IP
address, subnet mask, and gateway address; or to run diagnostics
and isolate system problems through a local or remote terminal.
• Redundant FRUs that are removed or replaced without
disrupting product or link operation, and a modular design that
enables quick removal and replacement of FRUs without the use
of special tools or equipment.
• Concurrent port maintenance. FPM, UPM, and XPM cards and
SFP optical transceivers are removed, added, or replaced without
interrupting other ports or product operation. In addition, fiber-
optic cables are attached to ports without interrupting other ports
or product operation.
• Beaconing to assist service personnel in locating a specific port or
product in a SAN 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
LED on the product flashes. Beaconing does not affect port, FRU,
or product operation.
• Status monitoring of redundant FRUs and alternate data paths to
ensure continued product availability in case of failover. The SAN
management application queries the status of each backup FRU
daily. A backup FRU failure is indicated by an illuminated amber
LED.
• Data collection through the product's Element Manager
application, EFCM Basic Edition interface, or SANvergence
Manager application (for SAN routers) to help isolate system
problems. The data includes a memory dump file and audit,
hardware, and engineering logs.
