Greetings Joe,

1st - Have management agree on a chnage window. Perhaps one two to four hour session on the weekends and one or two before or after business hours during the week. (BTW - This is also a very good way to give your schedule some flex, add for getting out early a day or two each week. (I like leaving at noon on Friday becuase of something I did last Sunday)

2nd - Make the case to allow for fallback/recovery/CYA by having some spare chassis' around to pre-configure. This can be especially handy with Sup's and such, as if the new one fails we just slide the old one back in.

3rd, However long you believe it is going to take - double that and forward to management through whatever change control methodology your company has accepted. 95% of the time you'll complete the task well within the window, you'll look like an ace, and the other 5% will be "unforseen" (cabling, bad ports, macrobends in fiber patch cords, etc... = Not your fault) - This is where your fallback/recovery becomes key so the situation does not become an RPE (Resume Producing Event). Again, even in an unsuccessful scenario you come out looking like you are on top of it - still an 'Ace.

4th, Last but not least - Open a TAC Case beforehand just in case you require immediate "emergency network down" assistance. It's much easier for everyone if this is setup ahead of time. If I have a *major* core upgrade I usually bump the code off TAC and even the NSP list on occasions.

If you would like to email me directly I can offer some examples I have documented, knowing history does indeed repeat itself. It's nice to have.

HTH,
~M

This is off topic but pretty pertinent for me these days...

I do not have a good frame of reference for estimated
installation/configuration hours for the various equipment that we as CCIE's
are asked to put into production (routers/switches/VoIP/CCM/Unity, etc.)

Is there a manual or documentation somewhere as to what teh basic rules of
thumb are? Not looking for 100% accuracy, just ball park stuff...

Joe
