Installing the Switch

switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.

Connecting to a 100BASE-FX Port

If you connect fiber cable to the 100BASE-FX module, be sure you use an SC-type connector. When inserting the cable, be sure the tab on the plug clicks into position to ensure that it is properly seated. If you use an SC-to-ST converter, run cable from the Rx (Tx) port on the module to the Tx (Rx) port on the target device. Note that the fiber optic ports operate only at 100 Mbps, full duplex. In this mode, you can run a fiber optic link up to 2 kilometers (1.24 miles).

Caution: The media expansion modules are not hot-swappable. Be sure you power off the switch before installing any of these modules.

Note: As a general rule, the length of fiber optic cable for a single switched link should not exceed 2 kilometers (1.24 miles). However, budget constraints must also be considered when calculating the maximum cable length for your specific environment.

Connecting to a Gigabit Fiber Optic

Port

When connecting fiber cable to a Gigabit fiber-optic port on the switch, be sure you use an SC-type connector. Follow the steps below.

Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

1.Remove and keep the SC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics.

2.Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

3.Connect one end of the cable to the SC port on the switch and the other end to the SC port on the other device. Since SC connectors are keyed, the cable can be attached in only one orientation. When inserting the cable, be sure the tab on the plug clicks into position to ensure that it is properly seated.

All the SC-type ports operate at 1000 Mbps with support for auto-negotiation of duplex mode (full/half) and flow control. Also note the maximum length for
