Problem with Black Box Hub

I have a Black Box 16-port Workgroup Hub, but when I plug it in, all of the lights flash and the flashing don't stop. Any ideas on what is wrong with it?

It may be helpful to know what hub it is? Does it work? Larry

It is a BLACK BOX Workgroup/16-Hub. It doesn't work, but the all of the lights (the lights corresponding to each port and power) flash when I plug it in. So it is getting power... Just wondering if there is anything in particular that sounds wrong with it.

Ok, I think I found it on Page 1040 of 1999/2000 Fall/Winter Black Box Catalog… Code LE677A-R2 => http://catalog.blackbox.com.BlackBox/external/16696.pdf… The manual is not available online.

If you go to Black Box’s web site (http://www.blackbox.com/), click on Talk to a Tech at the top of any page, fill-out a very short form with your phone number, a tech from Black Box will call you back within 20 seconds!!! I did it. I got the call in about 10 seconds. Norm at Black Box said he will find the answer and post a message on this forum. Larry

From the symptom ( all leds flashing )it seems to be the internal power supply that may be the problem. This supply is a 110/220V autosensing supply and it can be switching between modes either due to a bad supply and/or an excessive draw on the supply ( a bad component on the PC board ). Either of these problems would require the unit be returned for repair. One other thing you may want to try though, is to power the unit from another AC outlet that is on a seperate circuit, the reasoning for this is if the AC supplied to the unit is either too low or too high, causing the unit to be unable to sense the supplied AC properly. The last being unlikely but possible.
