4. OPERATION | 2. SITE CONSIDERATIONS | |
The StackMaster TX12 normally requires no intervention beyond | The site for the StackMaster TX12 hub must provide: | |
occasionally monitoring the Power and Status LEDs. | • 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. |
