Installing the ICX 7750 in a remote stack

The ICX 7750-26Q, ICX 7750-48C, and ICX 7750-48F can support stacking distances of 10 kilometers.
To achieve maximum stacking distance, these ICX 7750 models must use Ruckus LR4 fiber optics. LR4 optics require high-power
operating mode and an advanced thermal profile to control the fan cooling system. As a result, LR4 optics can be used for
stacking only on specific ICX 7750 ports: 1/2/5 and 1/2/6 on module 2 (front panel) or 1/3/5 and 1/3/6 on module 3 (rear panel).
NOTE
The ICX 7750-26Q supports LR4 optics on module 2 ports 1/2/1 through 1/2/6. The stacking cable must be attached to
stacking port 1/2/1 or 1/2/4 (refer to the following figure). Port and trunk configuration are otherwise the same as for
any ICX 7750 stack.
On an ICX 7750 stack, you can configure stack-port x/2/5, stack-port x/2/6, stack-port x/3/5, stack-port x/3/6, stack-trunk x/2/5 to
x/2/6, or stack-trunk x/3/5 to x/3/6. Some combinations are not allowed. For more information, refer to "Valid-stack-port sets" in
ICX 7750 stack configuration overview
Port locations for potential stacking ports are shown in the following figures. Although different models are depicted, the port
locations are the same on all ICX 7750 units.
