Cabling Configurations
This section describes cabling configurations for the most common AsantéHub
applications.
•
Hubs can be interconnected via the RJ-45, BNC, or AUI ports
(the 3-In-1 Uplink) on the rear panel. Redundant physical links
can also be installed. See the following four sections.
•
The PC or MAC which runs AsantéView can be connected
directly to the hub, or a modem can be connected, for remote
network management.
•
Network management connections between hubs can be
accomplished for out-of-band or in-band network management.
Out-of-band network management connections are illustrated
in this section; for in-band connections, see Appendix A,
“SNMP Configuration” in the AsantéView manual for your
version of AsantéView.
See the following sections for details.
!
Note: All RJ-45 cabling information given in this manual assumes
that you use straight-through cables, except where otherwise noted. For details
on cable construction, see Appendix C, “Pinouts and Cable Specifications.”
Interconnecting Hubs via the RJ-45 Port
The rear panel RJ-45 ports are used to interconnect hubs using RJ-45 extension
cables. There are two ways to interconnect two hubs using the RJ-45 ports. See
Figure 2-3.
The first method (daisy-chaining) needs to be used when any single hub is
interconnected by RJ-45 wiring to more than one hub. Since the 3-In-1 Uplink
can accept only one physical connection, the hubs are daisy-chained as follows:
•
Connect one end of the extension cable to the rear panel
RJ-45 OUT port of hub #1.
•
Connect the other RJ-45 jack to a front panel port on hub #2.
