Use of the 3-In-1 Uplink
The 3-In-1 Uplink includes the rear panel RJ-45 IN/OUT, BNC, and AUI ports
at the rear of the hub. The default setting for primary link selection is auto-
selection (see “Factory Defaults,” in this chapter.) On auto-select, the hub
uses the AUI, 10BaseT, and BNC ports, in that order, if more than one uplink
connection exists. Auto-selection occurs on hub power-up and reset.
!
IMPORTANT: The rear panel RJ-45 IN port as well as the BNC
and AUI ports, may be used as a thirteenth device port only if the 3-In-1
Uplink is not used (i.e. as in a standalone departmental network). Any
other usage will disrupt the network.
Note: Also see “Cabling for Redundant Links," in this manual, and see
information about the Port Control window for primary link selection through
software, in the AsantéView manual for your version of AsantéView.
Hub ID (MAC Address)
Hub ID is a six-byte number identical to the hub's MAC (Medium Access
Control) address. It resides in the hub PROM. The format of the ID number
is 00-00-94-xx-xx-xx.
If you are using Windows Out-of-Band software, the hub ID is automatically
retrieved when a new hub is connected to the network. If you are using
Macintosh Out-of-Band, or the Macintosh or Windows versions of in-band
network management, see the appropriate users' guides for information on
configuration.
Default Settings
Factory default settings are listed below in Table 1-3 . The hub contains two
jumpers that can be reset to change certain options (see settings 1 and 2 on
the following page). You must also set two switches (see settings 4 and 5 on
the following page). Complete instructions for switch settings are given in the
section “Installation,” in this chapter.
