Allied Telesis GS900/5E manual Maximum Distance

Chapter 1: Product Description

Maximum Distance

Each twisted pair port has a maximum operating distance of 100 m (328 feet).

Type of Cabling

For 10 Mbps operation, Category 3 or better 100 ohm shielded or unshielded twisted pair cabling is required. For 100 or 1000 Mbps operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling is required.

Auto MDI/MDI-X

All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3ab- compatible. When a port's speed and duplex mode are set through Auto- Negotiation, the port uses the auto-MDI feature to automatically configure itself as MDI or MDI-X when connected to an end-node. Consequently, you can use either a straight-through or crossover twisted pair cable when connecting any network device to a port.

LEDs The system and port LEDs on the front panel of the AT-GS900/16 and AT-GS900/24 switches display the switch and its port status information. See Figure 3. Each port has two LEDs.
