Stacking on the 62xx series is accomplished by installing stacking modules into Bay 1 only on the left rear lf the chassis at ports XG1 and XG2. [IMAGE] • Unit 1 and Unit 2 are connected through the XG1 ports on each switch. • Unit 2 and Unit 3 are connected through the XG2 ports on each switch. • Unit 1 and Unit 4 are connected through the XG2 port on Unit 1 and the XG1 port on Unit 4.   The resulting ring topology allows the entire stack to function as a single switch with resilient fail-over capabilities.   The PC6200 switches when stacked require that the same version of firmware be installed on every switch member.
Hello All,   I'm attempting to connect a PowerConnect 6224 using a SFP+ module in 1/xg1 to an existing stack of PowerConnect switches. The other SFP+ module is installed in Unit 2 of the stack, in 2/xg3 (Unit 1 is the master).   The new switch, and all existing switches are all running the same firmware version: 3.2.2.3   Here are the details of the existing stack. ========================================================== IOD036#show systemSystem Description: Dell Ethernet SwitchSystem Up Time: 0 days, 00h:24m:39sSystem Contact: Brian WalshSystem Name: IOD036System Location: SFVT Network RackBurned In MAC Address: 5C26.0AE4.E27ESystem Object ID: 1.3.6.1.4.1.674.10895.3011System Model ID: PCT6248Machine Type: PowerConnect 6248Temperature Sensors: Unit     Temperature (Celsius)    Status----     ---------------------    ------ 1        29                      OK 2        27                      OK 3        28                      OK Fans: Unit     Description    Status----     -----------    ------ 1       Fan 1          OK  1       Fan 2          OK 1       Fan 3          OK 1       Fan 4          OK 2       Fan 1          OK 2       Fan 2          OK 2       Fan 3          OK 2       Fan 4          OK 2       Fan 5          OK 3       Fan 1          OK 3       Fan 2          OK 3       Fan 3          OK 3       Fan 4          OK Power Supplies: Unit     Description    Status         Source----     -----------    -----------    ------ 1       Main           OK             AC 1       Secondary      OK             DC 2       Main           OK             AC 2       Secondary      Not present    DC  3       Main           OK             AC 3       Secondary      OK             DC IOD036# ========================================================== IOD036#show stack-port                        Configured  Running                        Stack      Stack      Link       LinkUnit    Interface       Mode       Mode       Status     Speed (Gb/s)---- ---------------- ---------- ---------- ------------ ------------1    xg1              Stack      Stack      Link Up      121    xg2              Stack      Stack      Link Up      121    xg3              Ethernet   Ethernet   Link Down    Unknown1    xg4              Ethernet   Ethernet   Link Down    Unknown2    xg1              Stack      Stack      Link Up      122    xg2              Stack      Stack      Link Up      122    xg3              Ethernet   Ethernet   Link Down    Unknown2    xg4              Ethernet   Ethernet   Link Down    Unknown3    xg1              Stack      Stack      Link Up      123    xg2              Stack      Stack      Link Up      123    xg3              Ethernet   Ethernet   Link Down    Unknown3    xg4              Ethernet   Ethernet   Link Down    Unknown ==========================================================   Ultimately, I want the new switch to be a stack member, but I can't even get ethernet connectivity between the switches at all at the moment. When I tried to change the stack mode of 2/xg3 to "Stack", using:  config stack stack-port 2/xg3 stack exit copy running-config startup-config reload   It reverts back to ethernet. It's as if the module in the second bay isn't being recognised. I've powered down & reseated the module, but haven't seen any changes.   Any ideas?   Brian
