Appendix A –Troubleshooting
The HUB7M is a generic USB hub and should provide years of trouble-free service. Should the device appear to
not be functioning correctly, the following tips can eliminate most common problems without the need to call
Technical Support.
1. Make sure the power supply is connected to the hub and to a live AC power outlet. The green LED on
the front of the unit will be lit, indicating the hub is properly powered. Inspect the power supply or call
for a replacement if the green LED does not light after connecting to power.
2. Make sure the hub is connected to a USB port using the included USB cable or quality replacement USB
cable. The yellow LED will be lit when the hub is properly enumerated by the operating system.
3. The hub is supported in any USB aware operating system that supports generic USB hub devices,
including Windows 98/ME/2000/XP/Vista/7™operating systems and Linux (kernel v2.4 or better).
Check to make sure that USB support is enabled in the System BIOS, and it is functioning properly in the
operating system. This can be done by using Device Manager in Windows.
4. If the red LED lights, there is a fault condition with one of the downstream USB ports. When a
downstream USB peripheral pulls more than 500mA of power, the over current protection current will
shut down the hub until the problem is resolved.
5. Disconnect your USB peripherals one at a time until the red LED goes out. Inspect the problem USB
peripheral and replace, if necessary. Try connecting a different USB peripheral to the problem port. If
the red LED lights on the same USB port with a different device, contact technical support for further
assistance.
If these steps do not solve your problem, please call Sealevel Systems’ Technical Support, [phone]. Our
technical support is free and available from 8:00 AM to 5:00 PM Eastern Time Monday through Friday. For
email support, contact [e-mail].
