Port one seemed to be assigned to VLAN1 which I didn't think I was using. I moved the connection from our existing network in to port 2 - which then gave me access to the web interface where I could see for certain that VLAN10 (management) was on port 2 only on each switch in the stack. [IMAGE] So, I can at least get more visibility of what is happening now which should help going forward. This effectively closes my issue of not being able to assign an IP address - VLAN1 seems to not allow that, but my VLAN10 does.
Currently we have an existing data network - 10.10.10.0 (255.255.255.0). We have a EqualLogic PS4000 and two PowerConnect 6224 switiches in a stack. I have done the following so far:  enable configure spanning-tree mode rstp flowcontrol  vlan database vlan 10 vlan 100 exit  interface vlan 1 exit interface vlan 10 name Management exit interface vlan 100 name iSCSI exit ip address vlan 10  interface port-channel 1 switchport mode access switchport access vlan 10 exit  interface ethernet 1/g1 switchport access vlan 10 channel-group 1 mode auto exit  interface ethernet 2/g1 switchport access vlan 10 channel-group 1 mode auto exit  interface ethernet 1/g2 switchport access vlan 10 exit  interface ethernet 2/g2 switchport access vlan 10 exit  interface range ethernet 1/g3-1/g24 switchport access vlan 100 no storm-control unicast spanning-tree portfast mtu 9216 exit  interface range ethernet 2/g3-2/g24 switchport access vlan 100 no storm-control unicast spanning-tree portfast mtu 9216 exit  exit copy running-config startup-config  So, what I hope has happened is that ports 1-2 on each switch in the stack can be connected to our existing network to allow me access to the switch's http interface over that network. The remaining ports should be for use by the SAN. Currently I can't see the switches on our existing network - despite plugging in a network cable to port 1 on switch 1 - which flashes like it's getting used. I have tried to set an IP address on vlan 10 but I'm told that I can't have routing on the management vlan. I'm sure I've overlooked something but I'm very new to configuring switches like this!
