Table 21: Diagnostic tips for stack errors
Tip Problem Solution
1 Stacking is disabled on the switch. 1. Connect a console cable to the switch and
establish a console session, as described in
(Optional) Connect a Management Console.
2. From the CLI config context, enter the command
stacking enable.
3. Recheck the switch LEDs:
• Stacking Port LED back to Solid green.
• Port LEDs in user mode are all in green color.
NOTE:
• Slow green flash LED
represents stacking member ID.
• Fast green flash LED represents
commander member ID of that
chassis.
• Other solid green LEDs
represent other stacking
members.
2 The Stacking Module was installed in the switch
while the switch was powered on. Hot install is not
supported.
Reset or power cycle the switch to reboot it. After
rebooting, the module will be correctly recognized
and supported by the switch, and will be
operational.
When installing or removing the stacking module,
the switch must be powered off.

One of these problems exists:
• The stacking cable connected to the stacking
port on which the Link LED is blinking orange is
not connected at the far end.
• A stacking link failure has occurred on a link that
was functioning:
◦ The switch at the other end of the stacking
cable has been powered off.
◦ The stacking feature is disabled on the switch
at the other end of the stacking cable.
◦ The stacking module or switch at the other
end of the stacking link has failed.
◦ The stacking cable is faulty.
Make sure that the stacking cable is fully connected
at both ends of the link.
If an equipment failure has occurred, see the LEDs
on the device at the other end of the connection.
If this error occurred on an operational stack, it
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 HPE ArubaOS-Switch Advanced
Traffic Management Guide for your switch OS
version for more information.
If necessary to resolve the problem, contact your
Hewlett Packard Enterprise authorized network
reseller.
