Connecting the Switch System

CheetahSwitch Workgroup-2027

Mounting the Switch

This switch can be placed directly on your desktop, or mounted in a rack.

Before you start installing the switch, make sure you can provide the right operating environment, including power requirements, sufficient physical space, and proximity to other network devices that are to be connected. Verify the following installation requirements:

•Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3Hz). The switch's power supply automatically adjusts to the input voltage level.

•The switch should be located in a cool dry place, with at least 10 cm. (4 in.) of space at the front and back for ventilation.

•Place the switch out of direct sunlight, and away from heat sources or areas with a high amount of electromagnetic interference.

•If you intend to mount the switch in a rack, make sure you have all the necessary mounting screws, brackets, bolts and nuts, and the right tools.

•Check if network cables and connectors needed for installation are available.

Stacking Switches on a Flat Surface

The CheetahSwitch can be stacked anywhere there is a enough flat space, such as on a table or desktop.

1. Stick the self-adhesive rubber foot pads (that come with this package)

on each of the 4 concave spaces located on the bottom of the first switch.

2.Place the first switch on a firm flat surface where you want to install the stack.

3.Repeat step 1 for each switch before stacking them. The rubber foot pads cushion the switch against shock/vibrations and provide space between each switch for ventilation.

Mounting Switches in a Rack

Please comply with the following instructions to ensure that your switch is securely mounted in the rack.

1. Use a standard EIA 19-inch rack.

2. Use the brackets and screws supplied in the rack mounting kit.

3.Use a cross-head screwdriver to attach the brackets to the side of the switch.

4.Position the switch in the rack by lining up the holes in the brackets with the appropriate holes on the rack, and then use the supplied screws to mount the switch in the rack.

The CheetahSwitch has 24 RJ-45 ports and one AUI port that support connection to standard 10 Mbps Ethernet. It also has two slots for installing optional 100BASE-TX or 100BASE-FX Fast Ethernet Uplink Modules.

All ports support full or half-duplex operation. The transmission mode for the 10BASE-T, AUI and 100BASE-FX ports must be manually configured using the configure button or console interface. (See "Configuring the Switch" on page 7.) The transmission mode can be set for the 100BASE-TX ports using auto-negotiation (if also supported by the attached device). However, if the devices attached to

Quick Installation Guide

these ports do not support auto-negotiation, you can manually configure the port to match the transmission mode used by the attached device. You can also set the switching mode for any of the switch's ports to cut-through or store-and-forward using the console interface. (See “Using the Console Program” on page 7.)

Making a Connection via an MDI-X Station Port

You can connect any RJ-45 (MDI-X) station port on the switch to any device that uses a standard network interface such as a workstation or server, or to a network interconnection device such as a bridge or router (depending on the port type implemented on that device).

1.Prepare the devices you wish to network. Make sure you have installed 10BASE-T or 100BASE-TX network interface cards for connecting to the switch's RJ-45 (MDI-X) station ports. You also need to prepare straight-through shielded or unshielded twisted-pair cables with RJ-45 plugs at both ends. Use 100W Category 3, 4 or 5 cable for standard 10 Mbps Ethernet connections, or 100W Category 5 cable for 100 Mbps Fast Ethernet connections.

2.Connect one end of the cable to the RJ-45 port of the network interface card, and the other end to any available (MDI-X) station port on the switch. RJ-45 Ports

1 - 24 support 10 Mbps Ethernet connections (in addition to the AUI Port). If you ordered the 100BASE-TX uplink module, then you can also attach the switch to a 100 Mbps Fast Ethernet device. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. Using the switch in a stand-alone configuration, you can network up to 27 end nodes.

ΙDo not plug a phone jack connector into any RJ-45 port. This may damage the switch. Instead, use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).

2.We advise using Category 5 cable for all network connections to avoid any confusion or inconvenience in the future when you upgrade attached devices to Fast Ethernet.

Making a Connection via the MDI Daisy-Chain Port

1.To make a direct connection to another compatible switch or repeater hub, connect any RJ-45 (MDI-X) port on the switch to an MDI daisy-chain port on the other device. If you have a 100BASE-TX uplink module installed, then you can link to another switch or hub by running a cable from MDI-X to MDI ports on either device. (See "Connecting to an Uplink Module" on page 4.)

2.Prepare straight-through shielded or unshielded twisted-pair cables with RJ-45 plugs at both ends. Use 100W Category 3, 4 or 5 cable for standard 10 Mbps Ethernet connections, or 100W Category 5 cable for 100 Mbps Fast Ethernet connections. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.

Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).

2.To connect to another switch or hub, you may also attach to (MDI-X) station ports at both ends if you use crossover cabling.

3.To achieve best performance when cascading switches, group devices or segments that communicate most frequently on the same switch, and reserve the Fast Ethernet uplinks for connecting to the larger network.
