Re: Unable to sign into GS308E
I'm having some issues with this product. I recently purchased it and set it up last week. But as soon as I set it up via the admin page and enable Advance 802.1Q VLANs, then I'm no longer able to ...

If I do a factory reset, I'm able to reach the switch and redo the setup, but once I do, I can no longer reach the admin page.
A good point to continue might be-which- devices will be connected to the GS308E, -what- and -how- you are going to re-configure your switch(es) repeatedly in 802.1q.

One point I don't yet understand: These two ports on your security appliance for connecting the VLAN 10, 20, 30, and 40 - are these [T]agged or [U]ntagged?
This looks to me (on the first view) like four ports [U]ntagged, so access ports for each of the four VLANs.

Start with the default config om the GS308E, and set it to 802.1q mode.
Add VLAN 10, 20, 30, and 40.
Go the VLAN Membership, and select the respective VLAN, start with 10.
User Group Operation: [Tag All], then [Apply].
Repeat for VLAN 20, 30, and 40.

While talking: The reason you are able to discover the two GS305E and GS308E from the VLAN 40 (from an IP address in the ,40.x range) is that somehow any other switch and/or what is defined as VLAN 40 on your security appliance is somehow misconfigured (or completely unconfigured, or simply cross connected).
The discovery utility won't show any GS305E or GS308E(PP) model (in my testing) if connected to a different VLAN -and- IP subnet - so no NSDP is used anymore, it's pure SSDP. Some older GS1xxE(xx) might be discovered, because these are sill supporting NSDP and have never been updated.
