DIGI MIL-S3120 (01) PDF MANUAL

The MIL-S3100 family of dual speed switches has the following features:

• Complies with IEEE802.3, IEEE802.3U standard

• 4 or 8 10/100 Mbps switching ports

• Auto-Negotiation is supported for each port.

• One up-link port provided for cascading

• Visual diagnostic LED’s supported

• Palm size

• External power adapter

Before you begin, verify that your package contains the following items:

• 4-port or 8-port 10/100 dual speed switch

• AC power adapter

• Mounting kit for wall mount

• Installation guide

The LEDs on the front panel show the status of the switch’s power supply, connection speed (10 Mbps or 100 Mbps), data activity, and duplex mode (full/half).

LED	Color/State	Indication
Power	Green	The system detects the power signal.
	OFF	No power.
10 Mbps/Hdx/Act	Green	A good connection is established, and the 10 Mbps link pulse is detected. The operation mode is negotiated at full duplex.
	Flashing Green	The port operates in full duplex, indicating that data is being received or transmitted.
	Amber	A connection is established, and the 10 Mbps link pulse is detected. The operation mode is negotiated at half duplex.
	Flashing Amber	The port operates in half duplex, indicating that data is being received or transmitted.
	Off	No link established.
100 Mbps/Hdx/Act	Green	A good connection is established, and the 100 Mbps link pulse is detected. The operation mode is negotiated at full duplex.
	Flashing Green	The port operates in full duplex, indicating that data is being received or transmitted.
	Amber	A good connection is established, and the 100 Mbps link pulse is detected. The operation mode is negotiated at half duplex.
	Flashing Amber	The port operates in half duplex, indicating that data is being received or transmitted.
	Off	No link established.

The ports are used for connecting the switch to the desktops to form a small network. To improve the network efficiency, it is better to have 200 Mbps full duplex operation between the server and switch if the LAN adapter on the server can operate in full-duplex mode. The 10/100 Mbps speed and full/half duplex modes of the ports are automatically determined when users connect the switch to 10Base-T and 100Base-TX devices.

Switch-to-switch or switch-to-hub connections are made by connecting the uplink port (MDI) of the 10/100 Dual speed switch to a port of the other hub/switch. Use a straight-through Category 5 twisted pair cable. With 100Base-TX, the maximum network length is approximately 205 meters with UTP cable. The maximum length between hubs or switch-to-hub is 100 meters.

The 4 or 8-port 10/100 Dual speed switch can be mounted to the wall or to a flat surface by following these steps:

• Screw one of the enclosed 1/2-inch wood screws into the surface, leaving approximately 1/4-inch of the threads exposed.

• Hang the switch on the wall using the keyholes provided on the bottom of the switch.

This equipment generates and uses radio frequency energy and if not installed and used properly, may cause interference to radio and TV reception. If you suspect this equipment is causing interference, turn your switch on and off while your radio or TV is showing interference. If the interference disappears when you turn the switch off and reappears when you turn the switch on, something in the switch is causing interference.

You can try to correct the interference by one or more of the following measures:

• Plug the computer which has the equipment installed into a different power outlet so that the equipment and the receiver are on different branch circuits.

• Reorient the receiving radio or TV antenna where this may be done safely.

• If necessary, you should consult the place of purchase or an experienced radio/television technician for additional suggestions.

1. This product should be operated from the type of power source indicated on the marking label. If you are not sure of the type of power available, consult your dealer or local power company.

2. This product is equipped with a three-wire grounding type plug, a plug having a third (grounding) pin. This plug will only fit into a grounding type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding type plug.

3. Do not allow anything to rest on the power cord. Do not locate this product where persons will walk on the cord.

4. If an extension cord is used with this product, make sure that the total ampere ratings on the products plugged into the extension cord do not exceed the extension cord ampere rating. Also make sure that the total of all products plugged into the wall outlet does not exceed 15 amperes.

5. Never push objects of any kind into this product through cabinet slots as they may touch dangerous voltage points or short out parts that could result in a risk of fire or electric shock. Never spill liquid of any kind on the product.

6. Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage points or other risks. Refer all servicing to service personnel’s.
