Figure 2-4 Making VLAN Connections

Note: When connecting to a switch that does not support IEEE 802.1Q VLAN tags, use

untagged ports.

Application Notes

1. Full-duplex operation only applies to point-to-point access (such as when a

switch is attached to a workstation, server or another switch). When the switch

is connected to a hub, both devices must operate in half-duplex mode.

2. For network applications that require routing between dissimilar network types,

you can attach these switches directly to a multi-protocol router.

3. As a general rule, the length of fiber optic cable for a single switched link should

not exceed:

• 1000BASE-SX: 550 m (1805 ft) for multimode fiber

• 1000BASE-LX: 10 km (3.1 miles) for single-mode fiber

• 1000BASE-ZX: 80 km (62.1 miles) for single-mode fiber

However, power budget constraints must also be considered when calculating the

maximum cable length for your specific environment.
