ACTIVE STAR HUB
5. Installation
IMPORTANT!
If you haven’t already done so, please read the safety guidelines listed on page 1.
1.The Active Star Hub is designed to be placed in a 19" rack. The unit should be properly installed using all four mounting holes. Rack hardware is not provided. (For more information on rack hardware that will work with this unit, call Black Box Technical Support at
2.The external power supply is mounted on the rear panel of the Active Star Hub. Insert the AC power cord firmly into the external Power supply.
3.Insert the male end of the AC power cord into a properly wired receptacle. All data and mode LEDs on the Active Star Hub will light for two seconds and fade. The amber Power LED on the front panel and the green Power LED on the top of the external power supply will light and remain on.
4.The devices attached to each star segment must have unique addresses. Connect all the devices to the Hub’s jacks. The LEDs may momentarily blink as cables are attached. All Device Activity LEDs should be off. If any Device Activity LED remains on or flashes, refer to Chapter 6, Troubleshooting.
5.Connect the host to the host ports of the Active Star Hub. All Activity LEDs will sequentially light and remain on. If a port and its devices are Express- ready, then the Express data rate will activate and the Express mode LED will light. If any Activity LED does not remain on or flashes, refer to Chapter 6, Troubleshooting.
NOTE
The Express and standard modes are mutually exclusive at the port level. The AS/400 operates a port at the standard rate whenever a standard rate device is detected. The AS/400 operates in the Express mode when all of the attached devices are Express capable.
