Fan Tray
The E3800 switches have a field-replaceable fan tray. If necessary, the fan can
be replaced while the switch is operating. For more information, see
“Replacing the Fan Tray” on page 4-2.
HP E3800 Stacking Module
The HP E3800 4-port Stacking Module (J9577A) is a component you can add
to an HP E3800 Switch to provide high-speed stacking connections to other
E3800 switches. See “Stacking Information and Topologies” on page 2-23, and
the E3800 Advanced Traffic Management Guide for more information about
stacking configuration and operation.
