NXA-ENET24 Hardware Installation Guide
Stacking Switches
The switch supports stacking up to eight units through an SFP stacking transceiver. The stacking transceiver
must be installed in the port 25 slot. Each stacking transceiver has two connectors, Tx and Rx, for attaching
stacking cables. FIG. 16 on page 22 shows how stacking cables are connected between switches in a stack.
It is not possible to stack PoE switches with non-PoE switches; however, establishing trunks between the two
can provide similar results.
Installing a Stacking Transceiver
The stacking transceiver must be installed in the port 25 slot (FIG. 15). It should be inserted before any of the
systems in the stack are powered on.
Slide the SFP transceiver into the SFP transceiver slot until it clicks into place.
To remove, pull on the tab at the bottom of the front of the transceiver.
Connecting Switches in a Stack Using a Transceiver
To connect up to eight switches in a stack, perform the following steps:
1.
Install SFP stacking transceivers into the port 25 slot for each switch in the stack.
2.
Plug one end of a stack cable into the Tx (top) port of the top unit
3.
Plug the other end of the stack cable into the Rx (bottom) port of the next unit.
4.
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).
The stacking transceiver must only be installed in the port 25 SFP slot.
