Installing and Removing the Express Hub

Installing Multiple Hubs

This section describes building a stack of Express hubs. Included in this section are the guidelines for stacking and cascading Express hubs and the physical requirements for installing multiple hubs. Review the guidelines and requirements before installing your equipment.

Stacking and Cascading Hubs

You can connect multiple hubs together to increase the number of connections to your network. A stack of a maximum of six hubs can be installed in the standard 19-in (48.26-cm) equipment rack or on a shelf or a table. Once the hubs are stacked and secured either in the rack or on a table or shelf, you can connect them in the stack using Intel cascade cables.

The cascade cable is a unique cable for the Express hub. Use this cable to connect two adjacent hubs in a stack. You can connect two adjacent hubs as long as the distance between the two hubs is not greater than 2 inches (0.05 meters).

Physical Requirements for Installing Multiple Hubs

When you install a stack of Express hubs, consider the following installation requirements:

∙The mounting requirements for installing multiple hubs

∙The requirements for installing NMMs
