Error-Detection, Reporting, And Serviceability Features - HP StorageWorks Edge Switch 2/12 Service Manual

Error-Detection, Reporting, and Serviceability Features

The switch provides the following error detection, reporting, and serviceability
features:
Edge Switch 2/12 Service Manual
LEDs on the switch and adjacent to Fibre Channel ports that provide visual
indicators of hardware status or malfunctions.
FRUs–small form factor pluggable (SFP) optical transceivers–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 the use of tools or equipment.
System alerts and logs that display switch and Fibre Channel link status at the
EWS interface.
Diagnostic software that performs power-on self-tests (POSTs) and port
diagnostics (loopback tests).
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
IP address, subnet mask, and gateway address.
These parameters can also be changed through a Telnet session, access for
which is provided through a local or remote PC with an Ethernet connection
to the switch.
Data collection through the EWS 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 or 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 switch operation.
SNMP management using the Fibre Channel Fabric Element MIB (Version
1.1), Transmission Control Protocol/Internet Protocol (TCP/IP) MIB-II
definition (RFC 1157), or a product-specific private enterprise MIB that runs
on the switch. Up to six authorized management workstations can be
configured through the EWS interface to receive unsolicited SNMP trap
messages. The trap messages indicate product operational state changes and
failure conditions.
