Introduction
Network management is not required to make the PS Hub work, but
allows you to change the way it works and to monitor what is
happening to the segments and the rest of the network. There are
many features that can improve the operation of the hub or stack.
A stack of PS Hubs is treated as a single manageable entity, and the
management is distributed. This guide uses the word ‘
stack
’ to refer to
a stack of one or more PS Hubs, and ‘ management station ’ to refer
to the piece of equipment you are using to manage the stack (for
example a computer).
If the stack is connected and configured as recommended, the bottom
hub in the stack is unit number 1, the next hub up is unit number 2,
and so on.
All PS Hubs must be running agent software version 2.00 or later for
them to have the functionality mentioned in this user guide (for
example the web interface, CLI and load balancing). However, PS Hubs
that are running earlier agent software
are compatible with newer
PS Hubs but do not have the newer functionality.
You can use Quick Configuration Manager to see what versions of
management software are on the units in the stack, and to upgrade
the stack; refer to “Upgrading a Stack” on
page B-28 .
