Hey All DAWGS, I have many of the widebank 28's in my switch. I have a particular problem with one though and I have gone over an over the grounding. I keep losing my controller card in one certain unit. I am running about 20 of these along with a few adit 600's and some masterseries units. However my problem is with just this one unit! I actually am currently waiting for all 4 of my spare controller cards to come back from repair. My fingers have been crossed for about the last month cause if it blows again all my spares are in for repair! Any other suggestions anyone might have to where else I can look to try and narrow down this issue would be much appriciated. I have a lucent 5e onsite along with some ericsson bsc's and 1 lucent cdma bts and of course about a 300 foot guyed tower with a few sets of dishes on it feedin some alcatel 8000's. Thanks to All Suggestions in Advance! Keep goin DAWGS but get as much networking lan/vlan knowledge as you can from Uncle Sam before you leave, you will be worth lots of $'s when ever you decide to separate, I went from tower DAWG to wire DAWG to switch DAWG and All is Good!!
