APPLICATION NOTES

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.When a switch is connected to a hub or any kind of shared media, remember to turn off back pressure to prevent jamming packets from being propagated thoughout the hub.

3.For network applications that require routing between dissimilar network types, you can attach the TigerSwitch 10/100 units directly to a router.

4.As a general rule the length of fiber optic cable for a single switched link should not exceed:

•Gigabit Ethernet — 550 m (1805 ft) for multimode fiber or 5 km (16404 ft) for single-mode fiber.

•Fast Ethernet — 2 km (1.24 miles) for multimode fiber or 20 km (2.43 miles) for single-mode fiber.

However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment.
