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.
