Troubleshooting 45
Has the customer performed the Run Diagnostics feature?
1. Ask the customer to perform Run Diagnostics ("Running System Diagnostics" on page 56).
NOTE: In a cascaded configuration, the Run Diagnostics feature does not perform diagnostics on cascaded
console switches. The Run Diagnostics feature must be performed locally on each console switch. To locally
connect your cascaded console switch, refer to "How do I locally connect a cascaded console switch? (on
page 52)."
2. Ask the customer if any of the test failed ("When the Run Diagnostics test fails" on page 48) and, if
so, to take the necessary action.
Does the console switch detect a server connection?
1. Ask the customer to connect one of the RJ-45 ports ("Components" on page 71) on the rear panel of
the console switch to a server with an UTP CAT5 cable and an interface adapter.
2. Ask the customer to power on the server and ask if the connection appears on the OSD. The
connection should be "discovered" and reported by an EID, name, or port number.
Does the customer have the correct configurations?
1. Ask the customer to be sure that the console switch configurations ("Replacing the console switch" on
page 28) are correct.
2. Ask the customer to be sure that the cascade configurations ("Cascading console switches" on page
62) are correct.
3. Ask the customer to be sure that the cascaded console switches are powered on.
IMPORTANT: While updating the firmware, do not power off the console switch or attempt any
operations.
4. Ask the customer to be sure that the cascaded console switches ("Updating the cascaded console
switch firmware" on page 59) and all attached interface adapters ("Updating the interface adapter
firmware" on page 60) have updated firmware.
Are the cable connections correct?
1. Ask the customer to check all cable connections between the console switch, UTP CAT5 cables,
interface adapters ("Replacing the interface adapter" on page 43), expansion modules ("Replacing
the expansion module" on page 42), and servers.
2. Ask the customer if the interface adapter connectors are connected to the correct ports on the
attached servers.
3. Ask the customer if the correct interface adapters are being used. Only HP interface adapters can be
used with this product.
4. Ask the customer if a UTP CAT5 cable is connected from the RJ-45 port on the interface adapter to
the appropriate server port ("Components" on page 71) on the rear panel of the console switch.
5. Ask the customer if the UTP CAT5 cables being used are the correct cable length ("Connection
length table" on page 74).
6. Ask the customer if the standard UTP CAT5 cables supplied by HP are being used. The cables being
used must be unshielded twisted pair, utilizing all four pairs of wires.
7. Ask the customer if an expansion module is being used, and if so to be sure that the console switch
is connected to the IN port on the expansion module. The OUT ports on the expansion module
should be connected to the attached servers by interface adapters.
