NOTE: Port 1
of the Magnum 1000 Workgroup Hub (and the Magnum
RPM-TP
and
BPM-TP
) are equipped with a cross-over slide switch to accommodate
repeater-to-repeater connections without special cross-over connectors.
Set the slide switch to the “left” (for port 1) or “down” (for PM-TP) position
for normal twisted pair cable segments from the hub port to a user device. Set
the slide switch to the “right” (port 1) or “up” (for PM-TP) position for
cascaded or up-link segment connections to another repeater or hub in the
network. Verify proper switch position by noting that the port’s LINK LED
will illuminate when proper link is established.
3.3.2 Connecting ThickNet 10BASE5 (AUI)
Using the steps below as a guide, attach a new or existing 10BASE5 ThickNet
drop-cable directly to the AUI connector on the rear of the Magnum 1000 Workgroup
Hub or on the RPM-AUI or BPM-AUI port.
1. Plug the male end of the cable into the female AUI connector on the Magnum
1000 or PM-AUI card.
2. Engage the AUI connector slide lock to insure maximum connectivity.
3. Connect the opposite end of the cable into a network AUI port. (This
could be a network backbone transceiver, a hub or fan-out with an AUI
port, or an AUI Port Module in a concentrator.)
The AUI port may also used for connecting to other Ethernet devices using
standard AUI cabling. In this type of situation, it is important to consider the AUI
segment length to the attached device, including any cascading.
The maximum transmission distance between a backbone transceiver
equipped with an AUI connector and the AUI port of the Magnum 1000 will vary.
According to Ethernet standards, when an AUI cable is used to connect the Magnum
1000 directly to a backbone transceiver, the maximum AUI segment length of 50m (165
ft.) is allowed. If the Magnum 1000 is connected to a transceiver that has been cascaded
from another transceiver, the maximum AUI segment length is reduced as stated below.
Important Note:
The maximum transmission distance is decreased by 6m
(20 ft.) for every additional level of network transceiver device "dropped" or "cascaded"
from the original backbone transceiver tap.
The RPM-AUI connector supports standard IEEE signals, which are
summarized in Table 3.3.2.
