Removing The Physical Switch Unit From The Stack - Dell PowerConnect M8024-k User Manual

Stacking PowerConnect 10G Switches: M8024-k, 8024, 8024F
Note: An M8024-k modular blade switch does have a blue LED identifier for its Master only.
An easy way to find the Unit number and identify order of the stacked units is to use logging
commands. From the Telnet or Serial port CLI, perform the following.
console(config)#logging on
From the stack, create a link-up or link-down on any port for two to three seconds by either plugging in
or unplugging a cable, then reversing the action.
command in enable mode.
console#show logging
The log will identify both the Unit and Port that was used in the link operation. Continue this process
to identify all Unit numbers in the switch. If the show logging command is full, it can be saved off to
another location then cleared for easier reading. Also if the log is not needed, it can be cleared as
well prior to creating the link events.
To now identify which unit is the stack Master and which ones are members, type the following
command.
console#show switch
Management Standby
SW Status Status
--- ---------- --------- ------------- ------------- ------------- -------
1 Mgmt Sw
2 Stack Mbr
3 Stack Mbr Oper Stby PC8024
4 Stack Mbr
Note that in this example Unit 1 is the Master (Mgmt Sw) and Unit 3 is the Standby (Oper Stby)ready to
take over as Master in the event the Master fails.
Note: If the stack consists of M8024-k modular switches in an M1000e chassis, the CMC will also show
the fabric (A1, A2, B1, B2, C1, or C2) in which the Master is located.

Removing the Physical Switch Unit from the Stack

Before removing a physical unit from a stack, the administrator will need to prepare ports on the other
stack member units to receive the cables and traffic that will be redirected to them from the member
unit being removed. Consider all LAGs, VLANs, STP, ACLs, security, etc., that will need to be
configured on the new ports in order to accept cables, establish links, and begin to forward traffic. It
is highly recommended to not continue until these things have been considered and proper
preparations are made.
Note: Do not remove or re-route stacking cables until prompted in the last step below.
Check the log on the stack using the following
