Another room complete
Again, the Old LAN --
This in on the second floor of the main building, with quite a few more users. The Cabletron MMAC8 in the right hand rack has six cards providing 144 ethernet ports, a dozen cat-3 25-pair cables connecting to patch jacks in the left hand rack. As before, the whole 2nd floor is fed via a single 10baseFL connection -- SLOW!
At the top of the left rack is an Ungerman-Bass AH-16 hub. Seems as if there were these users on the second floor trying to access a server on the first floor who were wiping out the LAN -- so they got connected separately over their own fiber to the card on the MMAC-plus on the first floor that was also connected to that server, avoiding sending data on the rest of the LAN.
For the The new LAN I have three Cisco 3548 switches, connected on gigabit fibers on their own virtual LAN to the Cisco 5509 router/switches. Much cleaner.
