Salt Lake Upgrade
"Government is expanding to meet the needs of an expanding government."
The Phone Company, on the other hand, expands to meet real needs. The outside techs carry laptops around to get their workload and test and such. Thus they need access to our Corporate LAN.
The Salt Lake Garage was one of the first places I put an Ethernet LAN into -- running NetBuie instead of TCP/IP, a UB HIB instead of a switch, a little Cisco 1000 router, and a GDC modem running 56Kbps -- that's like dial-up speed. THis was a while ago, the latest computers were 286 powered and 20 meg hard disks were big. The 56K got upgraded to a T1. The single router was replaced with a pair and a pair of T1s. It went from sharing addresses citywide to having it's own set of 64 IP addresses. And ran out of addresses.
We are about to cut over to the latest configuration -- a pair of (existing) T1s, a pair of (existing) Cisco 2600s, and three 24 port switches to replace the existing singleton. Cutover to occur off hours. Why? I don't know. I would simply tell the users "I'm taking the LAN down for a while" and pull the plug! Cutover to be scheduled, but should be next week or the week after at the latest. I'm on vacation both weeks.
So, for whomever does the cut for me -- upon the OK to cut:
On the backside of the 2600 routers, switch the Ethernet cables (picture left.) If they have done their work correctly they'll be able to see the new switches, and the authentication switches. While they're checking you can pull the long cords from the old Ethernet switch and replace with short cords to the new switches.
When they are ready for the WiFi to be powered up, simply plug in the PoE power injectors (picture right.) At this point the LAN is done and the only thing left is to reconfigure the one LAN printer to a new IP address, and to give that address to someone to reconfigure the print queue to match.
