Managed 24-Port with Dual Gigabit Switch
The EtherFast®Managed 24-Port with Dual Gigabit Switch can be used as a
free-standing unit, or installed in any standard 19-inch rack.
Use the following instructions to rack-mount the Switch:
Before you begin, disconnect all cables from the Switch.
1. Place the Switch right side up, with the front panel facing you.
2. Position a mounting bracket over the screw holes on one side of the
Switch.
3. Secure the mounting bracket by inserting three screws into the screw
holes. Use a screwdriver to tighten the screws, ensuring that they are
fastened firmly in place.
4. Repeat steps 2 and 3 to install the other mounting bracket on the opposite
side of the Switch.
5. Insert the Switch into the 19-inch rack and secure it with suitable
screws (not provided). Ensure that the ventilation holes are not obstructed.
The rack-mount installation is complete.
You can now re-connect the cables to the Switch.
To power on the Switch, simply connect the AC power cord to the back of the
Switch, and then plug the power cord into an electrical outlet. The Switch
will boot up within approximately 30 seconds.
Any of the 26 ports on the EtherFast®Managed 24-Port with Dual Gigabit
Switch can act as an uplink port, allowing you to uplink to other switches or
hubs using a standard Ethernet connection. UTP Category 5e (or better)
cable is recommended when using the Gigabit ports.
To uplink the switch, connect one end of a network cable into the Switch,
then connect the other end of the cable into the desired network device’s
uplink port.

Installing the Switch

Fast Ethernet Considerations

If you will be using the Switch for Fast Ethernet (100Mbps) or Gigabit
(1000Mbps) applications, you must observe this guideline:
The maximum UTP cabling length using Category 5 cable is 328 feet (100m).

Full-Duplex Considerations

As previously mentioned, the Switch provides full-duplex support for its RJ-
45 ports. Full-duplex operation allows data to be sent and received simultane-
ously, doubling a port’s potential data throughput.
If you will be using the Switch in full-duplex mode, the maximum UTP cable
length using Category 5e (or better) cable is 328 feet (100 meters).

Positioning the Switch

Before you choose a location for the Switch, observe the following guide-
lines:
• Keep cabling away from sources of electrical noise, power lines, and
fluorescent lighting fixtures.
• Position the Switch away from water and moisture sources.
• To ensure adequate air flow around the Switch, be sure to provide a
minimum of one inch (25mm) clearance.
• Do not stack free-standing Switches more than four units high.
