Installing the Switch
Note: SFP transceivers are hot-swappable. The switch does not need to be powered off
before installing or removing a transceiver. However, always first disconnect the
network cable before removing a transceiver.

Connecting Switches in a Stack

An optional Stacking Module ships with one stacking cable. Figure 3-6 shows how
the stack cables are connected between switches in a stack.
Note: The stacking module must only be installed in port 25.
Note: The V2H124-24FX requires the V2STACK-2 stacking module.
To connect up to eight switches in a stack, perform the following steps:
1. Plug one end of a stack cable into the TX (right) port of the top unit.
2. Plug the other end of the stack cable into the RX (left) port of the next unit.
3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at
the TX port on the top unit and ending at the RX port on the bottom unit
(stacking up to 8 units).
4. Complete the stack connections by plugging one end of a stack cable into the
TX port on the bottom unit and the other end into the RX port on the top unit.
5. Select the Master unit in the stack by pressing the push button in on only one of
the stacking modules. Only one switch in the stack can operate as the Master,
all other units operate in slave mode. If more than one switch in the stack is
selected as Master, or if no switches are selected, the stack will not function.
