Stacking (SV8100 Chassis Only)
The idea of stacking allows the user the ability to manage multiple GSWU cards in one system as one
switch, instead of individual units and IP addresses, etc. For example, a set of three cards would appear
to the UI as a 24-port switch, instead of three 8-port switches.
Stacking will work by assigning a Master Management Card (or Main card), which will provide all the GUI
information for all cards in the same stack. The CCPU will assign the Main card by issuing an IP address
and configuring the Main Card assignment to the GSWU via data program. All other GSWU cards
detected in the system will not be assigned an IP address and will be configured as "Add-on", signifying
them as Add-on cards.
A PBX system can have up to 12 GSWU cards per system. However, only three GSWU units can be
grouped together to form a single 20-port switch. When more than three GSWU units are present within
a system, the units other than the three designated will not have any of the software features specified in
this document. They will behave as unmanaged Gigabit Ethernet switches.
Unmanaged Switch Functions
In the Unmanaged mode, a GSWU unit will have following functions only:
10/100/1000 Ethernet ports (x8)

PoE Class 1 (lowest power class)

Stacking Network Configuration
The GSWU Main board will maintain the network configuration and card initialization sequence. The
provision of IP address from the back plane will identify the Main board. If, during initialization, the IP
address is set to "0" by the CPU, then the card is determined to be an "Add-on" card.
