IBM 4002-Y2A, Installation And User Manual

Page: 47 / 96

1. Plug one end of an LC-LC MM fiber cable into one of the SFP+ stacking ports
of the top unit.
2.
Plug the other end of the cable into one of the stacking ports of the next unit.
3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting
with a stacking port on the top unit and ending at a stacking port on the
bottom unit (stacking up to eight units). See Figure 23.
4. (Optional) To form a ring stack topology, plug one end of an LC-LC MM Fiber
cable into the remaining stacking port on the bottom unit and the other end
into the remaining stacking port on the top unit. See Figure 24.
The 4002-Y2A, Y4A, Y2C, and Y4C devices can also be stacked with the 4002-Y2B
and 4002-Y4B devices. This requires installing the optional 2-port 10 GbE XFP
module on the 4002-Y2B and 4002-Y4B. You will need to configure the ports on the
2-port 10 GbE XFP module to be stacking ports using the
default-ports
command.
See the FastIron Configuration Guide for additional information.
