2. Site Planning
Site planning for the StackMasterTR Stack requires consideration both of
site conditions and of token ring standards.
2.1 Site Considerations
The site for the StackMasterTR Token Ring Stack must provide the
following:
• AC power outlet for each StackMasterTR Unit
• Adequate ventilation
• Standard environmental conditions
• Isolation from electrical noise, including radio transmitters and
broadbank amplifiers, motors, high power electrical lines, or
fluorescent light fixtures
Additionally:
• The token ring 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.
