Problem
Possible cause
Possible solution
The RJ-45 connector on the switch or LED
is faulty.
•
After checking and replacing the
cable, if no link LED displays, check
whether the port is transferring data.
If yes, the LED is faulty. If no, it
could be a faulty RJ-45 connector.
Call your service representative.
•
This could be caused by using a
crossover cable instead of a
straight-through cable.
The null modem cable is faulty.
Make sure that you use the null modem
cable provided by HP with this
hardware.
Cannot access the GbE2 Interconnect
Switch serial console interface using null
modem connection from a PC Terminal
Emulation Program.
The connection settings do not match the
GbE2 Interconnect Switch serial settings.
Make sure that the PC Terminal
Emulation session settings match the
GbE2 Interconnect Switch serial settings.
An error message that the GbE2
Interconnect Switch failed to complete
the system self-testing is displayed on the
serial console screen.
The system diagnostic tests failed.
Note the reason for the failure from the
serial console screen message and call
your service representative.
The keyboard locks up when using
HyperTerminal to log on to the GbE2
Interconnect Switch through the console
interface.
Scroll lock is on.
Press the
Scroll Lock
key on the keyboard
and make sure that the scroll lock is off.
The GbE2 Interconnect Switch is not
connected properly to the network.
Check the cable and connections and
make sure that there is network
connectivity between the GbE2
Interconnect Switch and the BOOTP
server.
The BOOTP server is not available on
the network or VLAN that is attached to
the switch management port.
Make sure that the BOOTP server is
present on the network or VLAN
attached to the GbE2 Interconnect
Switch.
The BOOTP server cannot offer IP
settings to the GbE2 Interconnect Switch
because no IP addresses are available.
Add additional IP addresses as
necessary.
The GbE2 Interconnect Switch fails to get
its IP settings from the BOOTP server,
even though by default it is configured
for BOOTP.
IMPORTANT:
If you are running in
spanning tree mode, it can take up to
2½ minutes for the GbE2 Interconnect
Switch to get its IP settings.
The GbE2 Interconnect Switch timed out
its request for IP settings.
Reset the GbE2 Interconnect Switch.
The GbE2 Interconnect Switch IP address
may not be configured or correct.
•
From the serial console interface,
make sure that the GbE2
Interconnect Switch IP address is
configured and valid on your
network.
•
Use the correct IP address to
establish the Telnet connection with
the GbE2 Interconnect Switch.
The setting allowing access to the GbE2
Interconnect Switch using the Telnet
interface is disabled.
From the serial console interface, make
sure that the Telnet interface is enabled.
Cannot connect to the GbE2
Interconnect Switch console interface
remotely using Telnet.
The management network address/mask
(if used) does not contain the IP address
of your management station.
From the serial console interface, make
sure that the Management Network
Address/Mask contains the IP address of
your management station.
