Dell 6248 Http Management Portal "Lost"

I've got a new Dell 6248 switch stack comprised of 4 switches with stacking modules.  I've got a few VLANs setup, and routing enabled.  I have the switches configured to work with the legacy network for testing purposes, etc.  All is working - dhcp relay / helper is functioning correctly, I'm being assigned an appropriate dhcp address / scope based on the VLAN membership.  

I cannot figure out how to access my vlan management portal via http or telnet.  I only have access through the console / serial cable.  I understand that the switch must be assigned to a vlan without routing enabled, and it (from my understanding) needs to be in it's own subnet.  I believe I have a routing issue, but I cannot access the web management portal.  What have I done wrong?

Is there an IIP address assigned to the switch default gateway?  the IP needs to go into the appropriat vlan and the default gateway is assigned at the base config level.  Also, you need to have a username and password at level 15 in order to access the box via telnet or http.

example:


username joe password betty level 15

Help me understand a little -

The management IP needs to be in the management VLAN.  The management VLAN cannot be a routable VLAN.  Because of these constraints I have placed the switch in it's own subnet / vlan.  I have not associated any VLAN with the address space of the switch.  I know I've got a connectivity problem with this config - what am I missing?  Do I need to create a routing rule in the switch to forward packets from VLANs to the core / management IP and vice versa?

Put the ip address in the management vlan.
Example:
Config
Inter vlan xx
Ip address (ip address of the mgmt vlan)

If that subnet is not routable, you will have to put your pc in the same vlan. You do this by making the port you are plugging into an access port in the management vlan.  Ex: switchport access vlan xx. (xx is the management vlan)

Hmm - That does seem logical - I could just manually assign the IP on the "management PC" so it's in the appropriate range.  As long as the port I'm using to access the management station is in the proper VLAN, I'll have no issues as the gateway is irrelevent.  It seems like this is mostly an issue on the core switch hosting the VLANs / VLAN Interfaces.  Am I correct in assuming the problem isn't as noticeable for an edge switch?  (The central VLAN configurations are hosted out of the network core - my edge switches essentially have the VLANs extended via trunks.)

Yes.  Just remember that dell will only pass vllans over trunks if you tell it to.
