Installing the Switch

3-6

3

This switch supports 1000BASE-SX, 1000BASE-LX, and 1000BASE-LH SFP 
transceivers. To install an SFP transceiver, do the following:

1.

Consider network and cabling requirements to select an appropriate SFP 
transceiver type.

2.

Insert the transceiver with the optical connector facing outward and the slot 
connector facing down. Note that SFP transceivers are keyed so they can only 
be installed in one orientation.

3.

Slide the SFP transceiver into the slot until it clicks into place.

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.

Note: SFP transceivers are not provided in the switch package.

Figure 3-6 shows how the stack cables are connected between switches in a stack. 
The connection is based on Gigabit Ethernet, using Category 5 or better cables. 

The 

switch supports a line- and ring-topology stacking configuration, or can be used stand 
alone.

In line-topology stacking there is a single stack cable connection between each 
switch that carries two-way communications across the stack. In ring-topology 
stacking, an extra cable is connected between the top and bottom switches forming 
a “ring” or “closed-loop.” The closed-loop cable provides a redundant path for the 
stack link, so if one link fails, stack communications can be maintained. Figure 3-6 
illustrates a ring-topology stacking configuration.
