4. OPERATION
The LANMaster T8 8-Port Ethernet Hub w/SIC Slot normally
requires no intervention beyond occasionally monitoring the Power
and Port Indicator LEDs.
Monitoring Power LED
The green Power LED is illuminated when the LANMaster T8 8-Port
Ethernet Hub w/SIC Slot is connected to external power.
Monitoring Port/Indicator LEDs
Each of the eight twisted pair ports has an associated LED:
• steady green data traffic is active on link
• flashing green port has been partitioned.

2. SITE CONSIDERATIONS
The site for the LANMaster T8 8-Port Ethernet Hub w/SIC Slot must
provide:
• AC power outlet for each LANMaster T8 8-Port Ethernet
Hub w/SIC Slot
• 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.
• If using Slide-in Card (SIC) connection between LANMaster
T8 Hubs, the maximum cable distances are:
Fiber Optic 2000 meters
10Base5 500 meters
10Base2 185 meters
10BaseT 100 meters
And:
• Since the LANMaster T8 8-Port Ethernet Hub w/SIC Slot
functions as an Ethernet repeater, the entire LANMaster T8
8-Port Ethernet Hub w/SIC Slot installation should comply
with the IEEE Ethernet 802.3 specification.
• RJ-45 connected cables should be configured as crossover
or straight through according to installation requirements.
