Error Detection, Reporting, And Serviceability - HP 316095-B21 Installation Manual

Error detection, reporting, and serviceability

The Edge Switch provides the following error-detection, reporting, and serviceability features:
• Light-emitting diodes (LEDs) on Edge Switch FRUs and adjacent to Fibre Channel ports that
provide visual indicators of hardware status or malfunctions.
• FRUs—small form-factor pluggable (SFP) optical transceivers, power supplies, and cooling fans
that are removed or replaced without disrupting Edge Switch or Fibre Channel link operation.
• A modular design that enables quick removal and replacement of FRUs without the use of tools
or equipment.
• System alerts and logs that display Edge Switch, Ethernet link, and Fibre Channel link status at
the HAFM Basic interface, HAFM appliance, or remote workstation.
• Diagnostic software that performs power-on self-tests (POSTs) and port diagnostics
(loopback tests).
• Automatic notification of significant system events (to support personnel or administrators)
through e-mail messages or the call-home feature at the HAFM appliance.
• An RS-232 maintenance port at the rear of the Edge Switch (port access is password protected)
that enables installation or service personnel to change the Edge Switch's Internet Protocol (IP)
address, subnet mask, and gateway address.
NOTE:
access for which is provided through a local or remote PC with an Ethernet connection to the
Edge Switch.
• Concurrent port maintenance—SFP trancievers and fiber-optic cables are removed and attached
to ports without interrupting other ports or Edge Switch operation.
• Beaconing to assist service personnel in locating a specific port or Edge Switch. When port
beaconing is enabled, the amber LED associated with the port flashes. When unit beaconing is
enabled, the system error indicator on the front panel flashes. Beaconing does not affect port or
Edge Switch operation.
• SNMP management using the Fibre Alliance management information base (MIB) 3.1 that runs
on the HAFM appliance. Up to 12 authorized management workstations can be configured
through the HAFM application to receive unsolicited SNMP trap messages. The trap messages
indicate operational state changes and failure conditions.
• SNMP management using the Fibre Channel Fabric Element MIB 1.1, transmission control
protocol/Internet protocol (TCP/IP) MIB-II definition (RFC 1213), or a product-specific MIB that
runs on each Edge Switch. Up to six authorized management workstations can be configured
through the Element Manager on the HAFM appliance, or the HAFM Basic interface resident in
the switch to receive unsolicited SNMP trap messages. The trap messages indicate operational
state changes and failure conditions.
These Edge Switch parameters can also be changed through a Telnet session,
