Introduction to McDATA Multi-Protocol Products 1 • 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, fiberoptic 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. 1-34 McDATA Products in a SAN Environment - Planning Manual
