General Information
Error-Detection,
Reporting, and
Serviceability
Features
The switch provides the following error-detection, reporting, and
serviceability features:
• Light-emitting diodes (LEDs) on switch FRUs and adjacent to
Fibre Channel ports that provide visual indicators of hardware
status or malfunctions.
• System and threshold alerts, event logs, audit logs, link incident
logs, threshold alert logs, and hardware logs that display switch,
Ethernet link, and Fibre Channel link status at the management
server, customer-supplied server (running the EFCM Lite
application), or a remote workstation.
• Diagnostic software that performs power-on self-tests (POSTs)
and port diagnostics (internal loopback, external loopback, and
Fibre Channel (FC) wrap tests). The FC wrap test applies only
when the switch is configured to operate in FICON management
mode.
• Automatic notification of significant system events (to support
personnel or administrators) through e-mail messages or the
call-home feature.
• An external modem for use by support personnel to dial-in to the
management server for event notification and to perform remote
diagnostics.
• An RS-232 maintenance port at the rear of the switch (port access
is password protected) that enables installation or service
personnel to change the switch’s internet protocol (IP) address,
subnet mask, and gateway address; or to run diagnostics and
isolate system problems through a local or remote terminal.
• Redundant FRUs; (small form factor pluggable (SFP)) optical
transceivers, power supplies, and cooling fans that are removed
or replaced without disrupting switch or Fibre Channel link
operation.
• A modular design that enables quick removal and replacement of
FRUs without tools or equipment.
• Concurrent port maintenance. SFPs and Fiber-optic cables are
removed and attached to ports without interrupting other ports
or director operation.
