Connecting Switches To The Stack's Backplane - Enterasys Vertical Horizon VH-2402S2 Hardware Installation Manual

Connecting Switches to the Stack's Backplane

The VH-2402S2 switches can be stacked together by installing optional
Stacking Modules. Each optional Stacking Module ships with one 32 cm
stacking cable.
The VH-STACK2 Stacking Module enables you to configure a closed-
loop architecture that provides fault-tolerant operation of the stack. If a
switch or Stacking Module fails, or if a stacking cable is disconnected, the
entire stack reboots and resumes normal operation and managment via
the redundant stacking cable (closed-loop cable).
Figure 2-3 shows how the stack cables are cascaded between switches
in a stack.
Figure 2-3. Connecting Switches to the Stack's Backplane
To connect up to seven switches to the stack backplane, do the following:
1. Plug one end of a stack cable in the UP port of the first (lowest)
switch.
2. Plug the other end into the DOWN port of the next higher switch.
3. Repeat steps 1 and 2 for each switch added to the stack. Form a
simple chain starting at the UP port on the first switch and ending at
the DOWN port on the last switch.
4. To form a closed loop, connect a 70 cm long stacking cable (order part
number VH-2402S-CBL) from the UP port on the top switch to the DOWN
port on the bottom switch.
