Issue stacking Dell PowerConnect 6224

This question is answered

Hi Guys,

I got an issue in stacking two 6224 Dell switches together.

I have tried to preconfigured the stack module port to stack mode and connect to the standby switch before power up the standby switch. It happen that both the switch is now the Management Switch, meaning there are not connected yet. 

The Running stack Mode is always in Ethernet mode eventhough I have configured it into stack mode. And the configured stack mode will change back to ethernet every time after reload every i have enter the copy run start command.

Appreciate if there is any help on this.

  • Thanks Daniel.

    I did one of the terrible mistake by not checking the module.

    The module I have used is not supported for stacking according to Dell Support.

    The Dell Part No. OU691D.

  • One of the easiest possible fixes is to simply ensure that both switches are on the same, current, firmware release.

    The next thing is to check the cabling of the stack and make sure it is setup correctly.

    Page 62 of the owners manual goes over these steps. And page 63 has a diagram.

    1. Connect one of the short stacking cables into either of the stacking ports of the top switch and the

    switch directly below it. Install a separately purchased stacking module in rear "Bay 1" of each of the

    switches in the stack.

    2. For each switch in the stack, connect one of the short stacking cables from stacking port one on the

    switch to stacking port two on the next switch.

    3. If necessary, use a separately purchased, long (3 meter) stacking cable to connect the switches. Repeat

    this process until all of the devices are connected.

    4. Use the remaining stacking cable to connect the remaining free ports, one each on the top and bottom

    switches.

    I would then run through the stacking steps that start on page 249 of the owners manual. This will just help double check and make sure nothing was skipped.

    If the settings are reverting back after a reload, I would double check to make sure the running config is being saved, before the reload command is given.

    Keep us updated,

    Thanks.

  • TQ for the reply.

    I have check the firmware, both of the switches are in same firmware which is 3.3.1.10.

    I have also follow the guide step by step and repeated for more than 10 times.

    I'm very sure I save the config by using copy run start command in both the switches every time before I reload.

    Appreciate if there is any other solutions?

    Thanks.

  • While this scenario is not exactly covered in the release notes for the current firmware, there are a few stacking issues addressed in the current release. I would still suggest updating both switches to the current revision and testing for any changes.

    Something else to look at would be the stacking cables themselves, do you have any others you are able to swap temporarily just to test and make sure the cables are good?

    Thanks.
