The AcerHub 528 Front Panel 

The following diagram illustrates the front panel of AcerHub  528. To dis-

tinguish model 528B or 528T, please see the label on the bottom side of

the hub.

1. PWR, the power (Green) Indicator 

When the  power  LED is lit it indicates that the hub’s power is on.

2. Collision (ORANGE) Indicator 

This LED indicator blinks when the hub detects a collision on the

network.

3. Link (GREEN) Indicators 

These LEDs indicate the state of the data link of each port. The

LED will be 

“ON” when the connection of that port is successful, and the LED

will be blinking when data is being received at  that port.

4. Partition (ORANGE) Indicators 

The LEDs will be “ON” when ports on the hub are been partitioned.

A port is partitioned if it experiences consecutive collisions. The

partitioned port is automatically isolated by the hub. The port will be

automatically recovered when the faulty condition disappeared.

When the port recovers, the partition LED returns to normal status

(“OFF”).
