Installing the Switch
Sample Network Topologies
Figure 2-31. Example of stacking three switches using CX4 and fiber.
Note Stacking the switches using 10-GbE is only applicable with the 3500yl and 
6200yl switches, not the 3500 10/100 switches.
Optimizing the 10-GbE Port Configuration
The 10-GbE ports on the ProCurve Switch 3500yl and 6200yl series are 
designed to deliver full 10 Gbps wire-speed to each port, where either one or 
two ports are in a linked state with another device. When three or four 10-GbE 
ports are in a linked state, the 10-GbE ports support an aggregate bandwidth 
of 28.8 Gbps across the linked ports.
As illustrated in the figure below, internally, there are two 14.4-Gbps channels 
between each of the 4 10-GbE ports and the switch fabric.
Line: 50/60 Hz.
