Managing the SAN Switch 2/32 Additional Diagnostic Tests The SAN Switch 2/32 uses diagnostic tests to help troubleshoot hardware and firmware. The diagnostic tests provided on the switch include tests of internal connections and circuitry, fixed media, and any SFP modules and fiber optic 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, and to verify the attached SFP and cable. All diagnostic tests are run at link speeds of both 1 Gbps and 2 Gbps. For information about the specific diagnostic tests and how to run them, refer to the HP StorageWorks Fabric OS 4.2.x Procedures User Guide. Note: The transmit and receive speed of the links may be temporarily locked to a specific speed during diagnostic testing. Field Replaceable Units You can replace the power supplies, fan assemblies, and motherboard in the field without the use of special tools. The power supplies and fan assemblies are keyed to ensure correct orientation during installation. Replacement instructions are provided with all replacement units ordered. Note: The SAN Switch 2/32 uses two AC power cords. To remove all power from the switch, disconnect both power cords before servicing. Power Supplies The two power supplies are hot-swappable if replaced one at a time. They are identical and fit into either power supply slot; see Figure 19. 64 SAN Switch 2/32 Version 4.2.x Installation Guide

Additional Diagnostic Tests
The SAN Switch 2/32 uses diagnostic tests to help troubleshoot hardware and
firmware. The diagnostic tests provided on the switch include tests of internal
connections and circuitry, fixed media, and any SFP modules and fiber optic
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, and to verify the attached SFP and
cable.
All diagnostic tests are run at link speeds of both 1 Gbps and 2 Gbps. For
information about the specific diagnostic tests and how to run them, refer to the
HP StorageWorks Fabric OS 4.2.x Procedures User Guide.
Note:
The transmit and receive speed of the links may be temporarily locked to a
specific speed during diagnostic testing.
Field Replaceable Units
You can replace the power supplies, fan assemblies, and motherboard in the field
without the use of special tools. The power supplies and fan assemblies are keyed
to ensure correct orientation during installation. Replacement instructions are
provided with all replacement units ordered.
Note:
The SAN Switch 2/32 uses two AC power cords. To remove all power from the
switch, disconnect both power cords before servicing.
Power Supplies
The two power supplies are hot-swappable if replaced one at a time. They are
identical and fit into either power supply slot; see
