48 Conversion “Issues”

Conversion “Issues”

Had to convert right-angle 25pr telco connectors to straight-in! Had to convert 15A outlets to 20A. Long vs. short-haul GBICs. Expensive MM to SM conditioning cables. Pulled a lot of new SM fiber. Fiber testing: Plug and Pray.

49 Conversion “Issues”

Conversion “Issues”

MSMs vs. MSFCs vs. MSFC/2s MSM: limited ACLs; No Appletalk routing. MSFC: too little RAM to run iBGP. DoS caused by unrestrained fast hosts on a fast network (Anime servers, etc.). Need to RTFM and turn on QoS RSN. So far only doing fair queueing. cost of Smartnet service contract.
