The 1 X 40-Gbps module supports stacking only when installed in rear panel slot 3 or 4.
The ICX 7450 supports 10-Gbps stacking when a 4X10GF module is present in slot 2. Each unit must be individually configured with default stacking ports as 1/2/1 and 1/2/3 and reloaded to join a stack, or to use secure setup. Refer to
Configuring 10-Gbps stacking ports on the ICX 7450 for more information on 4 X 10-Gbps ports.
Stack ports can be configured using the
stack-ports command.
ICX 7450 units support stack trunks only on a 4 X 10-Gbps (4X10GF) module installed in slot 2.
An IPsec module can be installed as an add-on in slot 2, 3, or 4 of an ICX 7450 device. Only one IPsec module should be installed in a stacking unit, and only one IPsec module is active in the stack at any time. A second IPsec module may be present in another stack unit; however, the second card does not provide active redundancy if the active IPsec module fails.
The secure-setup utility starts stack discovery on the stack port with the lowest port number, and that number is always on module 3 on an ICX 7450 40-Gbps stack. As a result, the switch unit IDs are allocated sequentially (1 , 2, 3, and so on) from the Active controller down to the stack port with the lowest port number (port 1/3/1 in an ICX 7450 40-Gbps stack).
When the secure-setup utility is used to configure an ICX 7450 stack, endpoints or ports of ending units that are not used for stacking are left as data ports, except on active units, where both ports 1/3/1 and 1/4/1 (or both ports 1/2/1 and 1/2/3 with 4 X 10-Gbps stacking) become stack ports as a result of the
stack enable command being executed.
