Cabling Fiber Optic Ports

AT-8500 Series Layer 2+ Fast Ethernet Switches Installation Guide

instructions on how to configure a port trunk, refer to the AT-S62 Management Software User’s Guides.

When you connect a device to a port on an AT-8524POE switch, the port automatically determines whether the node is a powered device and, if it is, the amount of wattage required by the device, up to a maximum of 15.4 W. If the node is not a powered device, the port automatically disables the PoE feature.

Warning

To reduce the risk of electric shock, the PoE ports on this product must not connect to cabling that is routed outside the building where this device is located. E40

If your switch has fiber optic ports, perform the following procedure:

1. Remove the dust covers from the ports, as shown in Figure 20.
