SYSTEM Status Light: 1
Look at the SYSTEM status light 1 (the green leftmost light under SYSTEM). If the light is:
• Off: Check the USB Server's power supply and its connection to an outlet. If you have done
this and the light does not turn on, please contact Keyspan technical support.
• On: If this light doesn't blink on/off within 6 seconds, the USB Server has failed to boot up.
Please try Resetting Your USB Server Hardware (as described later in this section). If it
still fails, contact Keyspan technical support.
• Blinking Slowly: This is normal and indicates the USB Server hardware is working.
Proceed to the next light.
• Alternating On/Off With System Lights 2 and 3: If the System 1 (green) alternates
on/off with either System 2 or 3 (red), so that when System 1 turns off, System 2/3 turns on
and vice versa, the USB Server has encountered an error while loading its firmware. Contact
Keyspan tech support for assistance.
USB Status Lights: 1-4
Look at the USB status light (any green light under USB). Next locate the light that corresponds to
the USB port that your USB device is connected to. If the light is:
• Off: Check the USB Server's power supply and its connection to an outlet. If you have done
this and the does not turn on, please contact Keyspan technical support.
• Blinking: This indicates the a) USB Server hardware does not support your USB device b)
if you or is having problems communicating with the device. Please check the the USB
Server's USB Device Compatibility information (found in the Appendices) or contact
Keyspan for further support.
The USB lights will also blink if you have exceeded the number of USB devices per server.
The USB Server support up to 8 USB devices on one USB Server. While many USB
devices appear as one USB device, components of Compound USB devices (a device with an
embedded hub or a device that has multiple components tied together by an internal USB
hub) will count as one device each. For example, the Lexmark X1150 is a compound device
that has 2 components (one for the scanner, one for the printer). The Canon i475D is also a
compound device that has 3 components (the printer, the card reader, and a HID device [for
buttons on the printer]). If you connect four X1150 devices you are still under the 8 device
limit and the USB lights will not blink. If you have 3 Canon i475D, you have 9 USB devices
and are over the limit therefore the light will blink.
Tech Note: While most USB devices will work with the USB Server, certain
incompatible USB devices can be supported via future software updates from
Keyspan. Please check the USB Device Compatibility appendix or contact
Keyspan for more information about compatible devices.
• On: This is normal and indicates the USB Server supports your USB device. Proceed to the
