Magnum DS80F & DS80C Dual-speed Stackable Hubs Installation and User Guide (12/01)

100Mb speed for guaranteed high performance. The DS80F’s fiber port is factory-built as either

amulti-mode ST, multi-mode SC or single-mode SC connector. The 100Mb fiber port will run at 100Mbs speed at all times with manually selected full- and half-duplex capability. The 100Mbps fiber port is a switched port and performs as a domain, providing a high bandwidth backbone connection (no media converter is required!) and supporting long (up to 40km) fiber cable distances for installation versatility.

Ports 1SW and 2SW (the switched ports) have a common “F - H” user-selectable manual switch. When set in the “F” position, it causes full-duplex mode to be advertised for the standard 802.3u auto-negotiation session on RJ-45 ports, and for the fiber port, it forces full- duplex mode at 100Mb. When set in the “H” position, it causes half-duplex mode to be advertised for RJ-45 auto-negotiation, and for fiber it forces half-duplex mode.

On Magnum DS80F units, there are three LED’s for the switched ports. One (LK/ACT) is steady ON to indicate LINK, blinking indicates the port is transmitting and receiving. The SPEED LED is ON for 100Mbps and OFF for 10Mbps (when LINK is made). The F/H indicates full-duplex when ON, when it is OFF, operation is half-duplex.

A fiber cable must be connected to the 100Mb port and a proper link (LK lit) must be made with the device at the other end of the cable in order for these LEDs to provide valid indications of operating conditions.
