configured in a stack with as many as 3 total units. The two shared traffic domains
automatically expand to support all of the ports in the stack. Any combination of 10 and
100Mbps ports, up to the maximum 48 ports (3units) in one stack, can be use at any
time. In a stacked configuration, the complete stack operates as one logical dual-speed
repeater. Depending upon the stack configuration (any mix of Magnum 8000Xs,
Magnum 8016s units), up to 48 front Ethernet segments with any mix of fiber and
copper ports is supported.
The Magnum 8000X is compact in design at only 1.75 in. (4.4 cm) high, and
has a lightweight metal enclosure. It is easily rack mounted in a standard 19" rack and
typically operates as the central hub for a multiple-backbone Ethernet network.
2.3.1 The Magnum 8000X Fiber Hub Chassis
The Magnum 8000X chassis houses one main PC board and an internal
bridge module (daughter board). There are 16 front slots for mixed-media modules.
Each front slot in the dual-speed chassis can accept any 8000X Port Module (PM)
which will provide either 10 or 100Mbps operation over either fiber or twisted pair
cabling. The 8000X is configured by selecting individual PMs, one per Ethernet port to
be used. Configured 8000X units provide two traffic domains, one each with IEEE
802.3 and 802.3u repeater functionality.

LEDs to indicate operating status are on the left front side. There are power
(PWR) and bridge-inside (BR) indicators for the unit. There are collision (COL)
indicators for each of the 10 Mbps and
100Mbps domains for visual indication
of the operating status of each domain,
and two activity (ACT) indicators for
traffic activity on each domain. These
LEDs provide a visual assessment of the
operational condition and aggregate
network activity of all segments installed in the unit.Figure 2.3.b: Front Panel LEDs
