Trying to get admin access to a 2nd EdgeSwitch (aka switch B). My setup:
I have two EdgeSwitch Lite 48-port switches linked with SFP+, both configured with 4 VLANs
10.10.4.0/24 VLAN 4
10.10.8.0/24 VLAN 8
10.10.16.0/24 VLAN 16
192.168.1.0/24 VLAN 1 (management)
EdgeSwitch A is configured as a router, with SVIs for VLANs 4, 8, & 16. VLAN1 is not routed.
Port 0/1 on each switch is set for VLAN1, and I can manage the switches at fixed IPs 192.168.1.2 (switch A) and 192.168.1.3 (switch B) when a cable is attached to 0/1 on the appropriate switch.
I can also manage switch A from a PC on any of the VLANs, by using the SVI (gateway) address (e.g. 10.10.4.2). This is how I manage that switch 99% of the time.
Question: How can I access the admin interface on switch B while at my desk connected to one of the VLANs (in the same manner I can with switch A)? Not surprizingly 192.168.1.3 does not work. Should I switch the address of switch B to, for example, 10.10.4.254 and the management VLAN to 4? I have recevied "subnet conflict" errors when attempting such a change in the past (I am not at the switches to try it at the moment).

Unlike an SVI, the management network is not routable. So you will not be able to 'inter-VLAN' route between the management VLAN and another routed VLAN (SVI).
Assuming you have a trunk between these switches. You can just change the management VLAN on switch B to VLAN4 and the management address to be in the 10.10.4.0/24 range.
