HI! I have A Bcm 400 3.7 hard drive failed , I have the Keycodes etc.Can i just replace with new 3.7 hard drive the and put in the key codes thru The Bcm mangager , and program greetings or do i have to intialize the new hard drive thru the serial port?? If so i don't have the 400 manual and new hard drive procedure. Thanks

If it isn't preloaded you will have to intialize the drive

Had to make sure this site was still there

MUCH easier to buy a pre-imaged drive! You don't want to mess around with the imaging tool (or worse, Norton Ghost) to try & restore the thing.

Keycodes won't be an issue 'cause the system ID will be the same. You might have to do that funky procedure from the serial port to "sync" the new HD with the MSC card.

HI ! I installed the refurbished Bcm hard drive, but may not of followed the instructions of just starting it up and entering keycodes, i ended following the reintialize start-up with the Null modem cable , thru serial port, every thing seems find , but the voicemail shows 3 digit mailbox #s, and the tel. system is 4 digit?? I reboot system but didn't help?? Any body got any ideas?? Need help. Thanks
