2. SITE CONSIDERATIONS

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 satin” wires 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.
