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
