Figure 10: RJ-45 Ports
In the majority of cases category 5 UTP cables that are used for 100BASE-TX connections
should also work for 1000BASE-T, providing that all four wire pairs are connected. However,
it is recommended that for all critical connections, or any new cable installations, category 5e
or category 6 cable should be used. The category 5e and 6 specifications include test
parameters that are only recommendations for category 5. Therefore, the first step in
preparing existing category 5 cabling for running 1000BASE-T is a simple test of the cable
installation to be sure that it complies with the IEEE 802.3-2005 standard.

SFP/SFP+ Slots
Several Fast Ethernet and Gigabit Ethernet SFP transceivers for different distances are
available. For 10G applications, SFP+ transceivers are used. Basically, two kinds of SFP
modules are available. Single mode transceivers are used for 9/125 µm single mode fiber.
While further transceiver for 50/125 or 62.5/125 µm multimode fiber are used. All SFPs
require LC/PC connectors. Do not combine multimode modules with single mode fiber or with
versa. That would cause increased damping, back reflections or oversteering of the receiver.
SFP modules are hot pluggable. You can install or remove a SFP from a slot without having to
power off the switch.
Figure 11: Installing a SFP Transceiver
Step 1: Consider network and cabling requirements to select an appropriate SFP transceiver
type.
Step 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.
Step 3: Slide the SFP transceiver into the slot until it clicks into place.
The following steps describe the connection with the fiber network:
Step 4: Remove and keep the LC port’s rubber plug. When not connected to a fiber cable, the
rubber plug should be replaced to protect the optics.
Step 5: Check that the fiber terminators are clean. You can clean the cable plugs by wiping
them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber
terminators on fiber optic cables will impair the quality of the light transmitted through the
cable and lead to degraded performance on the port.
Step 6: Connect one end of the cable to the LC port on the switch and the other end to the
LC port on the other device. Since LC connectors are keyed, the cable can be attached in only
one orientation.
