ISR has extra hole on it…

January 31st, 2008 • Related • Filed Under

Ok so I’m in the lab today and noticed that a great many of the 2811’s I have in front of me have a small hole located just under the CF LED however a great many of other 2811’s do not have the same hole located on them…So I couldn’t figure out what the little hole was for, at first I thought it may be an extra hole for grounding the unit…I looked all over the 2800 series hardware documentation on CCO and still nothing. So finally I broke down and asked someone from the business unit what that little hole was for and come to find out if for installing an optional CF guard on the routers and the reason I could not find any reference to it on CCO is that its documented in 1800 and 3800 series hardware documentation but not the 2800 series…In case some of you want to see what I referring to here are the pictures:
