6.5.2 Installation
6.5.2.1 Stacking Architecture
Stacking allows the user to manage the multiple Gigabit Switch
Unit (GSWU) cards in one system as one switch, instead of
individual units and IP addresses. For example, a set of three
blades would appear to the UI as a 24 port switch instead of
three 8-port switches. Stacking works by assigning a Master
Management Card which provides all the GUI information for all
the blades in the same stack. The CCPU assigns the Master by
issuing an IP address via PAW/PRW. All other GSWU cards
detected in the system are assigned as Slave blades.
A single system can have up to 12 GSWU cards per system.
However, only three GSWU units can be grouped together
forming a single 20 port switch. When more than three GSWU
units are present in a system, the additional units do not have
any software feature specified in this document. They behave
as an unmanaged Gigabit Ethernet switch.
The three GSWU boards can be categorized into one Main
board, with two Add-on boards.
