6.4.2.1 Stacking Architecture
Stacking allows the user to manage the multiple CD-ETIA
blades in one system as one switch, instead of individual units
and IP addresses, etc. 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 CD-CP00 assigns the Master by issuing an
IP address via PAW/PRW. All other CD-ETIA blades detected in
the system are assigned as Slave blades.
A single system can have up to 12 CD-ETIA blades per system.
However, only three CD-ETIA blades can be grouped together
forming a single 20 port switch. When more than three CD-ETIA
blades are present within a system, the additional blades do not
have any software feature specified in this document. They
behave as an unmanaged Gigabit Ethernet switch.
The three CD-ETIA blades can be categorized into one Main
blade, with two Add-on blades.
6.4.2.2 CD-CP00 IP Address Assignment
The CD-ETIA Main blade is provided with an IP address from
the back plane CPU during the initialization sequence. The
provision of an IP address from the back plane identifies the
Main blade. If during initialization, the IP address is set to 0 by
the CPU, the blade is then determined to be an Add-on.
The IP address for the CD-ETIA is assigned in Program 10-55
on the system. It contains the settings for the IP Address,
Subnet Mask and Gateway IP Address.
