As an option, a Network Management Module can be inserted into
the bottom slot of any hub model to manage the entire stack. It
offers a variety of management options, including SNMP, RMON
and a web-based interface. The management features are
described in the Advanced Reference Guide included in the
Network Management Module package.
This module also includes an RS-232 port for out-of-band
management and a Master LED which is described below.

A stack can support two Network Management Modules. The
module highest in a stack is active and the other module is placed
in standby mode. The standby module automatically takes over if
the active module fails.
Note: Do not install more than two Network Management
Modules in a stack.
