Effective cable distances are determined by ambient RF noise and  
by signal loss in the cable. Since fiber has low signal loss/meter  
and invulnerability to RF noise, fiber is the preferred medium for  
extending distances.

2. SITE CONSIDERATIONS  
The StackMaster TX12 normally requires no intervention beyond  
occasionally monitoring the Power and Status LEDs.  
The site for the StackMaster TX12 hub must provide:  
AC power outlet for each hub  
Adequate ventilation  
Standard environmental conditions  
Isolation from electrical noise, including radio transmitters  
and broadband amplifiers, motors, high power electrical  
lines, or fluorescent light fixtures.  
Additionally:  
The twisted pair cables should not run in the same conduit  
with power line cables  
Phone lines should be separated from data cables  
Flat or silver satinwires should not be used.  
And:  
Since the StackMaster TX12 functions as an Ethernet  
Repeater, the entire installation should comply with the IEEE  
Ethernet 802.3 specification.  
Status LEDs  
Status LEDs are located at the front of the StackMaster TX12.
