- Hewlett-Packard SAN Switch Installation Guide

8. If you are installing the 4/8, 4/16 or 4/32B SAN Switch, verify that a plenum (an
air duct that attaches to the switch rails, enabling the switch to draw cooler air into
the switch from outside the rack, rather than drawing in heated air from within the
rack.) is preinstalled, as shown in Figure 15.
If not installed, see Installing the Plenum (if required), page 49 to install a plenum
on the 4/8, 4/16 or 4/32B SAN Switch.
If not installing one of the devices listed in step 8, g o to Securing the switch to the
outer rails, page 50 to complete the rack mount procedure.
