31 Edge Switch 2/24 Installation Guide
Operational Features
The Edge Switch 2/24 supports several operational features including:
■
Advanced error detection, reporting, and serviceability.
■
Support for multi-switch fabrics.
■
Software diagnostics to aid in fault isolation and repair.
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.
■
FRUs (SFP transceivers and integrated cooling fan and power supply
assemblies) 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, Ethernet link, and Fibre Channel
link status at the EWS interface, HAFM appliance, or remote workstation.
■
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 Internet connection to
the switch.
■
Data collection through the EWS interface or Element Manager of the HAFM
applications 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.
