Installing Dust Covers In Empty Ports; Replacing An Sfp Transceiver; Diagnostic Tests - HP 16Gb SAN User Manual

Installing dust covers in empty ports

The dust covers included in the 16Gb SAN Switch shipping carton (see
be inserted in ports where SFPs are not installed. Installing dust covers ensures proper air flow and
helps reduce dust contamination.

Replacing an SFP transceiver

In some cases, you might need to reinstall an SFP transceiver.
To remove an SFP transceiver:
1. Press and hold the cable release.
2. Remove the cable from the transceiver.
3. Pull the bail (wire handle) to release the transceiver.
4. Grasp the bail, and gently but firmly pull the transceiver out of the port.
5. Repeat this procedure for the remaining ports as required.
To install a replacement SFP:
1. Make sure that the bail is in the unlocked position.
2. Orient the SFP with the appropriate port (see

3. Insert the SFP into the port until it clicks.
4. Close the bail.

Diagnostic tests

In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the hardware and
the firmware, including tests of internal connections and circuitry, fixed media, and the transceivers
and cables in use.
Initiate diagnostic tests with the command line, using a Telnet session or a terminal setup with a
serial connection to the switch. Some tests require the ports to be connected by external cables to
allow diagnostics to verify the serializer/deserializer interface, transceiver, and cable. For
information on available diagnostic tests, enter diagHelp or portcfgdport.
