The IE340L-18GP switch has two SFP slots for Ethernet 1000Base-X fiber
optic, MSA-compliant SFP transceivers.
You can use transceivers to connect switches to other network devices
over large distances, build a high-speed backbone network between
network devices, or connect high-speed devices, such as servers, to your
network.
Refer to the product data sheet for a list of supported Ethernet
transceivers.
To protect SFP transceivers from heat-related damage, you should select
transceivers whose maximum operating temperatures exceed the
anticipated maximum ambient temperature at the switch installation site.
Table 3 provides recommendations for SFP maximum operating
temperatures for several ambient site temperatures.
