Note: This procedure may take a few minutes longer than updating a single, non-stacked switch. Perform another show version command to see the new firmware has been downloaded to all members of the stack. Notice the firmware was only copied into the backup image for each member. console#show version Image Descriptions active : backup : Images currently available on Flash unit active backup current-active next-active ----- ------------ ------------ ----------------- ----------------- 1 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.1 2 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.1 3 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.1 4 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.1 The backup column now shows the same values as the active column. The next step is to activate the image that contains the new firmware by using the boot system backup command. console#boot system backup Activating image backup .. console#show version Image Descriptions active : backup : Images currently available on Flash unit active backup current-active next-active ----- ------------ ------------ ----------------- ----------------- 1 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.3 2 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.3 3 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.3 4 5.0.0.1 5.0.0.3 5.0.0.1 5.0.0.3
Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F 32 Notice the next-active column now shows the same version as the backup column. Next, type the reload command to complete the update. All switches in the stack reloads. console#reload Are you sure you want to reload the stack? (y/n) y Connection to host lost. The “Connection to host lost” message appears only if performing the reload from a telnet session. It will not appear if performing the command from a console session. Updating and rebooting the stack takes a few minutes longer than a single switch. After reload, the firmware upgrade is complete. To validate, login to the stack Master and perform a show version command. For the example given the following is displayed. console#show version Image Descriptions active : backup : Images currently available on Flash unit active backup current-active next-active ----- ------------ ------------ ----------------- ----------------- 1 5.0.0.3 5.0.0.1 5.0.0.3 5.0.0.3 2 5.0.0.3 5.0.0.1 5.0.0.3 5.0.0.3 3 5.0.0.3 5.0.0.1 5.0.0.3 5.0.0.3 4 5.0.0.3 5.0.0.1 5.0.0.3 5.0.0.3 Notice as the backup becomes active, the active becomes the backup. Web interface method Find the firmware versions the stack members are using. Select System > File Management > Active Images. Look in the Current-Active column to find which images are enabled. In this example all three switches are currently using image2. Note: It is acceptable if some units are using image1 and others are using image2. Since image2 is active, look in the Image 2 Version column to see what version each stack member is at. These firmware versions being used should be the same across all stack member units.
Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F 33 To find the firmware versions the stack members are using, go to System > File Management > Active Images. Each member of the stack will be updated with the latest firmware simply by updating the Master switch. The screenshot below demonstrate how to copy the firmware to the Master using a TFTP server. The stack needs access to a TFTP server on the network and the firmware file needs to be present in the download folder of the TFTP server. From the System > File Management > File Download page, select the appropriate settings. The most common settings are shown here.

Click Apply. A warning will appear.
Click OK.
Note: Be patient as this procedure may take several minutes longer than updating a single,
non-stacked switch.
The following screen appears for several minutes while the firmware is being downloaded to the Master
and distributed to all members of the stack.

Once the file has been distributed to the entire stack, the following dialog box appears.
Click Close.
Go back to the Active Images screen to confirm that the new firmware was downloaded to all members
of the stack. Notice the firmware was only copied into the backup image for each member.
Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F 36 The next step is to activate the image that contains the new firmware using the drop-down menus in the Next Active Image column. In this example the backup image is selected for each unit. After selecting backup for each unit, click Apply. Go to the System > General > Reset page to reload the switch.
Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F 37 Click Apply to reload all switches in the stack. If the following screen appears, click OK. Click OK again if this screen appears. If either of the following screens appear, they are simply notifying the user that the network has been lost. This is only temporarily while the stack reloads.

Click OK if prompted with the above screen. Rebooting the stack may take a few minutes longer than a
single switch. After reload, the firmware upgrade is complete. To validate each switch, login again to
the Web UI of the stack Master, and then go to System > File Management > Active Images.
Notice that as the backup versions become active, the previous active versions now become the
backup. This allows the administrator to toggle back to the previous image if needed for
troubleshooting. Going back to the previous version is rarely ever used and must be done with extreme
caution if the newer firmware has been running a long time with several configuration changes since
the initial upgrade. Newer firmware can have dozens of valuable bug fixes that will not be there on the
older firmware.
Removing member units
This section provides guidance on how to remove member units from a stack while minimizing traffic
flow interruptions within the stack. Removing any member of a ring topology stack does not require a
reload of any member unit in the stack.
If a unit in the stack fails, the Master unit removes the failed unit from the stack and no changes or
configuration are applied to the other stack members; however, the dynamic protocols will try to re-
converge as the topology could change because of the failed unit. When there are no connected ports
on the failed unit, the stack will be intact without changes. The example below demonstrates how to
manually remove a single member while keeping the stack intact.

Command-line interface method
Since any interface on these switches can be used for stacking, make sure to verify exactly which ports
are being used for stacking so they are un-cabled and re-routed last. This information is found with
the following command.
console#show switch stack-ports

Te3/0/48 Stack Stack Link Up 10
:
Note: To narrow the list to only view ports configured for stacking, use the command show
switch stack-ports | include Stack. Make sure to capitalize Stack since the
command is case sensitive.
Look for interfaces shown to be in Stack mode. The logical stack unit number is represented in each
interface name. The first number in the interface name is the logical stack unit. For example,
interface Te2/0/21 is in logical unit number 2.
A blinking LED light can be generated on the back of each PowerConnect 81xx to locate each physical
unit. This blinking LED is useful when identifying physical units and ports for running diags, sniffing,
mirroring ports, and other basic troubleshooting. It is also helpful when adding, removing, replacing or
tracing cables associated with these interfaces. Use the locate switch command to blink the blue
“Locator” LED on the switch unit you are trying to locate.
console#locate switch 2
The LED locator light on switch 2 blinks for 20 seconds. The length of time the LED continues to blink
can be changed using the locate time command, where ssss is the time in seconds for the
LED to blink.
Removing the physical switch unit from the stack
Before removing a physical unit from a stack, prepare ports on the other stack member units to receive
the cables and traffic that is redirected to them from the member unit being removed. Consider all
Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F

LAGs, VLANs, STP, ACLs, security, and so on, that needs to be configured on the new ports to accept
cables, establish links, and begin to forward traffic.
Note: It is highly recommended not to 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.
Do not remove or re-route stacking cables until prompted. Disconnect all other links on the member to
be removed and re-route the traffic that was going through this unit so it now goes through the ports
that were prepared on the remaining stack unit members.
Caution: In the next step, make sure to keep track of all ports being used for stacking that
will be temporarily unplugged. They need to be re-cabled in the following step.
Only after re-routing the traffic through the remaining stack units, remove the stacking cables from the
switch to be removed. The switch being removed does not need to be powered off. Keeping the
switches power on automatically brings it to a stand-along state as the stack cables are removed. In
the example below (Figure 13), the red quad-breakout cable is removed along with the switch.
Cabling of five stacked units Figure 13.
Use the freed cables or new cables to connect the two switches together that were previously adjacent
to the switch being removed. Since there are multiple interface and cable types supported for
stacking, a different set of cables may be required to make this connection.
