1. Note A single stack member configuration is always present on stack capable switches even if they are not part of an actual stack The single switch is considered a stack of one Identifying Physical Units and Ports in a Stack The Dell PowerConnect 8024 8024F and M8024 k hardware did not originally include the stacking feature that was introduced in firmware 4 2 and therefore do not have all of the hardware features commonly found on stacking devices such as dedicated stacking ports locate LEDs or LCDs displaying stack unit numbers Alternative methods to obtain this information are described below The M8024 k modular blade switch does have a blue LED illuminating on all stack Masters Standby and Member units in the stack do not illuminate this light Once stacked using logging commands is an easy way to find a Unit number identify order of the stacked units and if using M8024 k identify the chassis a member unit is in 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 Check the log on the stack using the following command in enable mode console show logging lt 189 gt MAY 21 09 32 49 198 18 101 45 Link Up Index 301 Unit 3 Tag 0 20 If the log file is large look at or near the end bottom to find the most recen

Note While downgrading to a previous firmware is supported all features and functions that were not part of the previous firmware will be lost including those features and functions that were introduced in the current firmware in use Firmware version 4 2 or later must be active on all stack members in order for stacking to work Do not downgrade a stack to firmware version 4 1 x x or earlier Un Stacking 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 a member 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 47 Stacking PowerConnect 10G Switches M8024 k 8024 8024F 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 SFP interface on these switches can be used for stacking be sure to verify exactly which ports are being used so they are un cabled and re routed last This information is found with the following command console show switch stack ports
