ECTION TACKING
(This feature is only supported in the SV8100 Chassis)
The idea of stacking allows the user the ability to manage multiple ETIA 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 ETIA via data program. All other ETIA cards detected in the systemwill be
configured as "Add-on", signifying them as Add-on cards.
A PBX system can have up to 12 ETIA cards per system. The first three ETIA units
can be grouped together to form a single 24-port switch. The 4th card should be
changed in programming PRG10-55 as Main, the following two cards will become
Add-ons of this card. This can be repeated for the 7th and 10th cards, giving 4 stacks
of three cards. If all cards after the third are left as Add-ons they will operate in
unmanaged mode.
Unmanaged Switch Functions
In the Unmanaged mode, a ETIA unit will have following functions only:
Stacking Networking Configuration
The ETIA 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.
The IP address for the ETIA will be assigned in program PRG 10-55 on the SV8100.
It contains settings for IP Address, Subnet Mask and a gateway IP address.
Stacking Formation
When a ETIA determines that it is an "Add-on" by the configuration setting in Program
10-55-03, the Add-on ETIA will send a broadcast message to all the ETIA units in the
Chassis, until it receives an acknowledge message from a Main board.
