Instructions for connecting the Magnum DS880 Dual-Speed Hubs to the various Fast
Ethernet media are given in the following sections.
3.2.3 Connections to NICs which support Auto-Negotiation
The Magnum DS880 Dual-Speed Hub will function properly with NICs (Network
Interface Cards) which support Auto-Negotiation. The Magnum DS880 will establish link with
any NIC which can send and receive the Fast Link Pulse (FLP) coding for the 100BASE-TX
signaling system. When connecting a NIC to the DS880, it may be necessary to reload the NIC
drivers on the user device if the NIC has been communicating with a protocol other than
100BASE-TX (such as 10BASE-T). When 100Mb operation is agreed and in use, the 100Mb
LINK/ACT LED is illuminated, steady ON if no traffic or blinking when there is traffic.
3.3 Powering the Magnum DS880
Magnum DS880 Dual-Speed Hub incorporates an internal universal power supply, and
has a recessed male IEC connector for the AC power cord in the rear. A six-foot 115 VAC 60Hz
power cord is supplied with each unit shipped within the United States and Canada.
Each Magnum DS880’s auto-ranging power supply supports installation environments
where the AC voltage is from 90 to 260 volts with an input frequency between 47 and 63 Hz,
and consumes a maximum of 20 watts. In order to power down the unit, simply unplug either
end of the AC power cable.
