TTECH & 392 are correct.
You need to be careful in what environment you upgrade any PRE R3.0 ACS Processor. Lucent has had major problems with the PRE R3.0 power supplies. Maybe a class Action suit is in order - even as much as I love Bell labs genius', this is rediculous!
The PSs have many specific design or component issues that are easily fixed by properly rebuilding them. Those circuit boards - PRE R3.0 - also have port chips that are prone to failure. As standard repair procedure in our repair lab work, we are replacing ALL the 8 station port chips and haven't had one failure since we instituted this policy. It is an extra $25.00 cost but "good medicine". What is the cost to our reputation when a customer has an in-use failure of their processor? $25.00 seems fairly insignificant! Very strange issues with the older chips ... you would get a defective PRE R3.0 processor in for repair with say - 2 station chips out, and we replace these chips and rebuild the power supply ... then upon power up the other 6 chips would fail. If that didn't happen, some ports would fail usually within the next 90 days,
Another major problem we have seen happening out in the "market" is that refurb shops, remarketers etc. are relabeling the older processors. An easy visual test to tell if your processor's main board is PRE R3.0 is to look into the PCMCIA dual slots on the front of the shell. There is a small round white plastic board alignment stud that should always show on ALL ACS processors, but the PRE R3.0s don't have the on board built in small fuse on each side of the white round board post - just open green board space. It has got to be such a problem, that we have told all our dealers that we reserve the right to determine the actual release of any ACS processor that comes in for repair. We are now even seeing PRE R3.0s coming in with new complete ACS R5.0 labels. There is even a company on EBAY selling complete relabel kits????
Saving a few dollars for the risk of "in-use" failure just doesn't seem wise. Buy an "real" R4.0 where you can be sure it has the newer style design power supply and port chips as not ALL R3.0s from the factory had the newer style station port chips. We repair very few R4.0 and R5.0 processors unless they get serious power surges.
