Instant EtherFast® Series

The RJ-45 Ports

The Switch is equipped with four 10/100/1000 RJ-45 ports, shown in Figure 2- 2. These RJ-45 ports support network speeds of 10/100 Mbps half-duplex and 20/200 Mbps full duplex Ethernet and Fast Ethernet speeds as well as up to 2000 Mbps Gigabit speed. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it, and adjust its speed and duplex accordingly.

To connect a device to a
port, you will need to
use a network cable. If
you	are	using
100BaseTX		devices
you will need to use
UTP Category 5 (or
better)	cable.	Gigabit
devices	require UTP		Figure 2-2
Category 5e		cable (or	Figure 2-2
Category 5e		cable (or

Chapter 3: Installing the Switch

Pre-Installation Considerations

Fast Ethernet and Gigabit 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 simultaneously, 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 m).

Positioning the Switch

Before you choose a location for the Switch, observe the following guidelines:

•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 (25 mm) clearance.

•Do not stack free-standing Switches more than four units high.

Instant EtherFast® Series

Rack-Mounting the Switch

The Switch can be used as a free-standing unit, or installed in any standard 19inch rack.
