Backing Up the Configuration and Upgrade Firmware Removing an SFP In some cases you might need to remove an SFP transceiver, either because it is no longer needed or because you must replace it. To remove SFP transceivers: 1. Press and hold the cable release, as shown in Figure 19 on page 71. 2. Remove the cable from the transceiver. 3. Pull the bale (wire handle) to release the transceiver. 4. Grasping it by the bale, gently but firmly pull the transceiver out of the port. Caution: If the SFP you are removing does not have a bale, use a small implement such as a screwdriver to press the release trigger beneath the port. Non-baled SFPs can be damaged by the removal process and are not recommended. Refer to the HP StorageWorks SAN Design Reference Guide for a list of supported SFPs and devices. 5. Repeat this procedure for the remaining ports as required. Diagnostic Tests In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the hardware and the firmware. This includes tests of internal connections and circuitry, fixed media, and the transceivers and cables in use. The tests are implemented by command, either through a telnet session or through a terminal set up for 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. All diagnostic tests are run at link speeds of both 1 Gb/sec and 2 Gb/sec. Caution: Diagnostic tests can temporarily lock the transmit and receive speed of the links during diagnostic testing. For information about specific diagnostic tests, refer to the HP StorageWorks Fabric OS Procedures 4.2x User Guide. 72 SAN Switch 2/8V, 2/16V and 2/16N Installation Guide

SAN Switch 2/8V, 2/16V and 2/16N Installation Guide
Removing an SFP
In some cases you might need to remove an SFP transceiver, either because it is no
longer needed or because you must replace it.
To remove SFP transceivers:
1.
Press and hold the cable release, as shown in
Figure 19
on page 71.
2.
Remove the cable from the transceiver.
3.
Pull the bale (wire handle) to release the transceiver.
4.
Grasping it by the bale, gently but firmly pull the transceiver out of the port.
Caution:
If the SFP you are removing does not have a bale, use a small
implement such as a screwdriver to press the release trigger beneath the port.
Non-baled SFPs can be damaged by the removal process and are not
recommended. Refer to the
HP StorageWorks SAN Design Reference Guide
for a list of supported SFPs and devices.
5.
Repeat this procedure for the remaining ports as required.
Diagnostic Tests
In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the
hardware and the firmware. This includes tests of internal connections and
circuitry, fixed media, and the transceivers and cables in use.
The tests are implemented by command, either through a telnet session or through
a terminal set up for 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.
All diagnostic tests are run at link speeds of both 1 Gb/sec and 2 Gb/sec.
Caution:
Diagnostic tests can temporarily lock the transmit and receive speed
of the links during diagnostic testing.
