3. If you are installing this switch in a stacked configuration, repeat this procedure for each
switch until all switches have been installed in the stack, then proceed to "Connecting High‐
Speed Stacking Cables" on page 2‐6. Otherwise, proceed to "Connecting AC Power" on
page 2‐10.

Connecting High-Speed Stacking Cables

The stack of switches can be connected in a ring or daisy chain topology. In a ring topology all the
switches are connected. The only difference in the cable connections in a daisy chain topology is
that one cable is not installed. Up to eight switches can be stacked together and connected by high‐
speed stacking cables. You can add switches and reach up to a maximum of 384 Ethernet ports per
stack. The high‐speed stacking cables allow the entire stack to operate with a single IP address.
The high‐speed stacking cables are optional items that you must order separately. The B5 supports
the following stacking cables:
• STK‐CAB‐SHORT, a 30cm cable
• STK‐CAB‐LONG, a 1m cable
• STK‐CAB‐2M, a 2m cable
• STK‐CAB‐5M, a 5m cable
Figure 2‐5 shows an example of a four‐high stack connected in a ring topology. All STACK DOWN
and STACK UP connectors are used in the installation. The high‐speed stacking cable connections

Fastening the Switch to the Rack

Note: By default, the stack connection ports are covered with removable covers. If you are not
connecting stacking cables, keep the covers on the stack connection ports. If you remove the
stacking cables, you must replace the covers on the stack connection ports.
