Dell PowerConnect Management Vlan questions

Hi there,

I’m trying to get my management IP’s/Vlan assigned and working so that I can HTTP and telnet to my Dell PowerConnect 6248 switches for management instead of having to console cable in.  

I currently have 3 switch stacks, one ‘Main’ stack with routing enabled (client’s GW address are set to Vlan IP’s here) and two ‘Remote’ stacks.  The two ‘Remote’ stacks are connected directly back to the ‘Main’ stack with Fiber and Trunking is enabled for my Vlans, excluding the new management Vlan I just created.  

I can currently manage the Main/Routing stack by hitting one of the route IP’s, but the other two I’m not having any luck with.  

Here’s the management scheme I just created:

Stack 1      (Main, Routing)            Vlan 99            192.168.99.1
Stack 2                                 Vlan 99            192.168.99.2
Stack 3                                 Vlan 99            192.168.99.3

Now I know that the management Vlan isn’t routable, but I was under the impression that I would be able to get to it since they’re no ACL’s preventing this.  Is this not the case?  If not, then what needs to be done for me to be able to manage the switches from any of the other Vlan’s?  

A few other questions to help clarify:

-      Do I need to enable vlan 99 on my trunk ports between the ‘Main’ and ‘Remote’ stacks?  I don’t think this applies since I can’t even connect to Stack 2 from a different Vlan on Stack 2…

-      Do I need to assign a switchport access vlan 99 to an Ethernet interface, and if so, do I actually need to connect something to it?

-      Will I actually have to get another NIC and assign it an IP on the 192.168.99.0 subnet to be able to manage the stacks?

-      Do I need an IP default-gateway command anywhere in there?

Any help or clarification would be appreciated.  With the lack of Dell PowerConnect documentation I’m trying to get my head around this.

Thanks!
