If you don't have a network management platform or adequate documentation to co
nsult, there's one other option you have. Since the switch's sc0 is on a separa
te subnet, you'll have to do it from a workstation on the same subnet. Ping the
broadcast address of the subnet, then drop to a command prompt and view the wo
rkstation's arp table (arp -a on a windows box). You can either look through th
e list yourself, or copy and paste it into a text file and do a search for the
mac you're looking for. You can probably also do this from a router that has th
at subnet attached (I never have myself, but I can't see why it wouldn't work)
but you'll have to enable directed broadcasts first using ip directed-broadcast
on the LAN interface.
If that seems like a lot of work, it is. That's why organizations pay a grand o
r more for network management software.
