Nortel Networks 5625HD Giving a Server a Dedicated Port

Planning a Network with the Model 5625HD Switch Module

Giving a Server a Dedicated Port

Moving a server from a 10 Mb/s shared-media connection to a dedicated port

on the Model 5625HD switch module improves server response time and

increases throughput capacity. For even higher performance, the server could

be upgraded to 100 Mb/s and the Model 5625HD switch module would

autonegotiate for 100 Mb/s.

In Figure2-2, the “Before” example shows clients and servers sharing the same

network segment. The “After” example shows the same clients assigned to

different segments through a shared hub (either 10/100 Mb/s or directly

connected) and the original servers connected to switch ports on a Model

500xBH/BHC chassis. In addition, two servers have been added through 10/100

Mb/s connections.
