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. Avoid using flow control on a port connected to a hub unless it is
actually required to solve a problem. Otherwise back pressure jamming
signals may degrade overall performance for the segment attached to
the hub.
3. For network applications that require routing between dissimilar
network types, you can attach this switch directly to a router.
4. As a general rule the length of Gigabit fiber optic cable for a single
switched link should not exceed 550 m (1805 ft) for 1000BASE-SX
multimode fiber or 5 km (16404 ft) for 1000BASE-LX single-mode
fiber.
However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.
