Troubleshooting
Diagnosing with the LEDs
4
The stacking module on this switch has
experienced a failure.
The Test LED on the front of the switch may
also be blinking orange simultaneously.
1. Try resetting the switch by pressing the Reset button on the
front of the switch, or by power cycling the switch.
2. If the fault indication reoccurs, the stacking module may
have to be replaced.
This error could result in changes to the stack configuration
including election of a new stack Commander, and possibly a
new Standby. See the Stack Management chapter in the E3800
Advance Traffic Management Guide for more information.
If necessary to resolve the problem, contact your HP authorized
LAN dealer, or use the electronic support services from HP to
get assistance. See “HP Customer Support Services” on
page 5-15.

A stack link failure has occurred in a chain
topology and multiple stack fragments
have been created. Each fragment will
elect a Commander, so there will be
multiple switches with the Cmd LED on.
Repair the cause of the stack link failure and reconnect the
switches in their original topology so that the switches can
reform the original stack.
6
A stack link failure has occurred in a chain
topology and multiple stack fragments
have been created.
One of the fragments has been made
inactive according to the rules of the stack
operation. All the network ports on the
switches in the inactive fragment are
disabled. As a result, all the port LEDs are
off for those switches.
Repair the cause of the stack link failure so that the switches
can reform the original stack.

You have tried to merge two stacks that
have different Stack IDs – they were not
previously part of the same stack.
This is not allowed by the stack operation
rules.
1. Select one of the stacks as the one to retain.
2. For the switches in the other stack, erase their stacking
configuration by issuing the following config-level CLI com-
mand to each switch:
HP Switch(config)# stacking factory-reset
This erases the complete startup configuration for each
switch, including the stacking configuration.
3. Add the switches to the stack as described in the Stack
Management chapter in the E3800 Advanced Traffic
Management Guide.
8
You have tried to add an eleventh switch to
a stack. A maximum of ten switches can be
stacked together.
Disconnect the eleventh switch from the stack.
