StackPower Cabling Configurations
•
For rack-mounted switch stacks connected to the XPS 2200, review this recommended sequence of
events:
–
If you are using the XPS 2200, first install the XPS at the bottom of the stack. If needed, allow
one RU space between the XPS and the first switch above to provide room for cabling.
–
Connect all the 12-pin XPS cables to the XPS 2200 as needed.
–
Rack-mount the switches. If you have the optional 1100-W power-supply module, first
rack-mount the switch before installing the power-supply module.
–
Connect the XPS cable to the first switch above the XPS 2200. Connect the stack cables to the
first switch above the XPS.
–
Connect the XPS cable to the second switch above the XPS 2200. Connect the stack cables to
the second switch above the XPS.
–
Repeat until all devices are connected.
StackPower Cabling Configurations
This section describes the recommended cabling configurations for a StackPower stack. There are two
types of StackPower cables. The cable in
Figure 2-8
connects a Catalyst 3750-X switch to another
3750-X switch in a power stack or to an XPS 2200. The cable in
Figure 2-9
connects a Catalyst 3750-X
or 3560-X switch to an XPS 2200.
Warning
Attach only the following Cisco external power system to the switch:
XPS 2200.
Statement 387
Note
All cable connectors are keyed and color-coded, as are the connections on the switches (See
Figure 1-7
and
Figure 1-8 on page 1-19
).
Both cable types are available in two lengths.
