Cascading Personal Hubs With The Up-Link Port - GarrettCom magnum Installation And User Manual

Magnum Personal Hubs
is either the rear RJ-45 port (H50 and H90) or the right-most front RJ-45 port
(H40A and H80A). This switch is used to select either a normal 10BASE-T
connection to a user device (switch in the "==" position) or a 10BASE-T network
up-link connection to another hub or concentrator (switch in the "X" position).
NOTE: When the switchable port is connected for up-link but the
switch is set to the == position, the up-link segment is
inoperative and full bandwidth is available locally.

Cascading Personal Hubs with the Up-Link Port

Personal Hubs may be cascaded in order to expand networks. The
switchable up-link port (set to the X position) is normally used to connect the
Personal Hub to any port of another hub. Also, the Models H40A and H80A may
be connected to a backbone via the rear AUI port. With the addition of a mini-
transceiver, the AUI port may be used to connect to any standard Ethernet media.
Since each Personal Hub provides full repeater functionality, cascaded units can
operate together even though there may be a full segment of distance between
them.

Cascaded Personal Hubs: Full Repeater Functionality
NOTE: Based on the "four repeater rule" defined by Ethernet
there may normally be a maximum of four units in any one chain between any
two users.
Personal Hubs may also be cascaded with other Magnum Hubs (such as
Magnum 1000 Workgroup Hubs and Magnum 3000 Stackable Hubs and
Concentrators) as well as with Ethernet hubs from other manufacturers.
