When you connect your network devices, make sure you dont exceed the maximum cabling distances, which are listed in the following table:

4. Repeat steps 2 and 3 to connect additional devices.

Maximum Cabling Distances

5. Connect the supplied power cord to the power port on the Switchs back

Maximum Distance

Switch or Hub*

100 meters (328 feet) 1

5 meters (16.4 feet) 1

Switch or Hub

100 meters (328 feet) 1

6. Plug the other end of the power cord into an electrical outlet.

7. Power on the devices connected to the Switch. Each active ports corresponding LED will light up on the Switch.

*A hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A 10Mbps hub connected to another 10Mbps hub can span up to 100 meters (328 feet).

Appendix A: Glossary

Placement Options

There are three ways to physically install the Switch: set the Switch on its four rubber feet mount the Switch in a standard rack (1U high) hang the Switch on a wall using its wall-mount slots.

To rack mount the Switch, follow these instructions:

1. The Switch has four mounting holes on each side. Screw an included mounting bracket into each side.

2. Lift the Switch into the rack, and secure the brackets with additional screws

(not included).

To hang the Switch on a wall, follow these instructions:

1. The wall-mount slots are two crisscross slots on the Switchs bottom panel (see Figure 3-3).

The distance between the two slots is 95 mm. Attach two screws to the wall, so that the

Switchs wall-mount slots line up with the two screws.

Figure 3-3

2. Maneuver the Switch so the screws are inserted into the two slots.


The installation of the 10/100 Switch is complete.

10BaseT - An Ethernet standard that uses twisted wire pairs.

100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of

Category 5 UTP or STP wire.

Auto MDI/MDI-X - On a network hub or switch, an auto MDI/MDI-X port automatically senses if it needs to act as a MDI or MDI-X port. The autoMDI/MDI-X capability eliminates the need for crossover cables.

Auto-negotiate - To automatically determine the correct settings. The term is often used with communications and networking. For example, Ethernet

10/100 cards, hubs and switches can determine the highest speed of the node they are connected to and adjust their transmission rate accordingly.

CAT 5 - ANSI/EIA (American National Standards Institute/Electronic

Industries Association) Standard 568 is one of several standards that specify

categories (the singular is commonly referred to as CAT) of twisted pair cabling systems (wires, junctions, and connectors) in terms of the data rates that they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps and is usually utilized for 100BaseTX networks.

CAT 5e - The additional cabling performance parameters of return loss and farend crosstalk (FEXT) specified for 1000BASE-T and not specified for

10BASE-T and 100BASE-TX are related to differences in the signaling implementation. 10BASE-T and 100BASE-TX signaling is unidirectional-signals are transmitted in one direction on a single wire pair. In contrast, Gigabit

Ethernet is bi-directional-signals are transmitted simultaneously in both directions on the same wire pair; that is, both the transmit and receive pair occupy the same wire pair.

Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Has a transfer rate of

10 Mbps. Forms the underlying transport vehicle used by several upper-level protocols, including TCP/IP and XNS.

Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet

CSMA/CD network access method.

Hub - The device that serves as the central location for attaching wires from workstations. Can be passive, where there is no amplification of the signals; or active, where the hubs are used like repeaters to provide an extension of the cable that connects to a workstation.

SR224 24-Port 10/100 Switch

IEEE 802.3, IEEE 802.3u

Mbps (Megabits per second) - One million bits per second; unit of measurement for data transmission.

MDI (Medium Dependent Interface) - On a network hub or switch, a MDI port, also known as an uplink port, connects to another hub or switch using a straight-through cable. To connect a MDI port to a computer, use a crossover

MDI-X (Medium Dependent Interface Crossed) - On a network hub or switch, a MDI-X port connects to a computer using a straight-through cable. To connect a MDI-X port to another hub or switch, use a crossover cable.

Cabling Type

Network - A system that transmits any combination of voice, video and/or data between users.

Switch - 1. A data switch connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connectio
