A port is temporarily partitioned when a line error or too many collisions are
detected on the attached segment. While it is automatically partitioned, the
port continues to receive data from the segment. However, data is not
transmitted onto the segment. When the problem is corrected or a valid data
packet is received through the port, the port is automatically reconnected.
When partitioning occurs, the port’s corresponding
Partition LED will be
continually lit (RED light). Otherwise, this LED should be OFF (unlit).

Troubleshooting: If the Link LED does not light up when a device is connected to its
corresponding port, check that both the hub and connected device are powered on. Be
sure the cable length for all devices connected to the hub are within the limits described
under 'LVWDQFH/LPLWIRU)DVW(WKHUQHW&DEOLQJ in Chapter 2. When using twisted-pair cable, be
sure you use standard, straight-through cables and not crossover or other specialized
cables. When using fiber optic cable, be sure you use 50/125 m
m or 62.5/125 mm
guage multimode cable.
