Instructions for connecting the Magnum 8000X Mixed-Media Hubs to the

various Fast Ethernet media are given in the following sections.

3.6.2

Connections to NICs which support Auto-Negotiation

The Magnum 8000X Mixed-Media Hub will function properly with NICs

(Network Interface Cards) which support Auto-Negotiation. The Magnum 8000X 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 8000X, 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.

3.7

Table-Top or Shelf Mounting

The Magnum 8000X fiber Hub can be easily mounted on a table-top or any

suitable horizontal surface, and has four rubber feet to provide stability without

scratching finished surfaces.

3.8 Rack-Mounting

Installation of a

Magnum 8000X mixed-

media fiber Hub in a 19” rack is a simple procedure. The units are 1U (1.70”) high.

When properly installed, the front-mounted LED status indicators should be in plain

view and easy to read. Rack-mount installation requires special 19” rack-mounted

brackets and screws (included with each 8000X unit). The brackets attach to the front

sides of the hub, which is then fastened into a standard 19” RETMA rack.
