Switch Installation
Figure 11. Example high availability topology
N o t e
Install identical ProCurve 6120 switches in adjacent interconnect bays to support high avail-
ability. See figure 11.
Installing the Blade Switches in adjacent interconnect bays (as shown in Figure 8) allows for
the opportunity to enable the ISL(s). The 6120G/XG has one ISL and the 6120XG has two ISLs.
When enabled the ISL provides switch to switch connections, such as Ethernet crosslink ports
between matching switches. If this is done, be aware that it will cause a loop in this configu-
ration and spanning tree will have to be configured in order to create separate paths. See
for more information ISL port behavior. Refer to theManagement and Configuration Guide
for the Series 6120 Switches for more detailed information on using spanning tree.
