Table 1-3. AsantéHub 1012 Factory Default Settings
Default To Modify
1. All ports have Link Integrity testing
enabled. Jumper JP8 is set OUT to
enable Link Integrity testing on the 3-
in-1 Uplink.
If you are using AsantéHub with a pre-
10BaseT device, disable Link Integrity.
(You will not be able to obtain link
integrity status from disabled ports.)
To disable Link Integrity testing over the
3-in-1 Uplink, set JP8 IN.
To disable Link Integrity testing over
device links, use the Port Control
window in AsantéView.
2. Primary link selection follows auto-
selection sequence (see “Use of the 3-
in-1 Uplink,” in this chapter). Jumper
JP7 is set OUT.
To force primary link selection to AUI,
set jumper JP7 IN.
3. All front panel ports (RJ-45) are
hardware-configured IN and cannot be
modified.
To connect two hubs using front panel
ports, use a crossover RJ-45 cable (see
Appendix C for pinouts).
4. The rear panel AMS Link ports are
terminated (Through/End switch set
DOWN).
To configure hub as a through device on
the AMS Link (if both AMS Link ports are
occupied), set the Through/End switch
UP. The “through” setting passes the
signal to the next hub or to a PC
connected to this hub on an AMS Link
port.
5. The rear panel PC/Terminal switch is
set to Terminal (DOWN/ON).
To put the rear panel RS-232 port in PC
mode, set the PC/Terminal switch to PC
(UP/OFF).
6. EEPROM configuration for LX903
transceiver:
Port Disable = Not enabled
LI = Link Test enabled
JAB = Jabber detection enabled
PRC = Polarity Correction enabled
TH = Reduced Threshold not enabled
Reconfigure using Port Control window
in AsantéView.
