Network device in the roof space

[Simcfc73]

Hi,

 

I've only worked here a year and I'm still finding stuff.

 

I've just been down to one of the doors that wasn't responding in net2 which I couldn't ping. Took the cover off... NIC is flashing so traced the wore to this little beauty. No markings or brand.. just flashign away screwed in the roof space. 

 

Theres no power to it so presume its a poe switch repeater type thingy. 

 

I think the security firm must have wired it in cos I have no idea where it goes.

 

There is a VLAN setup for net2 but over half of the devices are just sitting on the main vlan which i am slowly fixing. 

 

Fun Fun Fun

Might be a bodgy way of extending a network cable run.

I've still found switches behind desks after 10 years of working in a school.

 

Looking up Mac addresses on switches can be quite useful in tracing this sort of thing back.

 

Unifi do a similar switch that can do vlans and be centrally managed. I still don't like having them hidden though.

I miss my UNIFI network which told me everything.

I once found a pc in an office and above it, resting on the tiles of the false ceiling, was a switch. The switch was providing service to the IT suite next door. The PC was not patched to the switch, and after some hunting I found it was **spliced** into the unbranded Cat5(e?) cable that was the uplink from that switch back to the server room.
