ACTIVE STAR HUB
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 724-746-5500.) We recommend that
you use plastic or nylon washers under mounting screws to protect the Hub's
finish.
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.
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.
