Faulty Base Function Tray

Some BCM200 and BCM400 system Base Funtion Trays were manufactured with faulty capacitors (in a green casing) which can bulge and/or leak causing a failure. Nortel issued a Product Advisory (ID 2005006321) for BFT replacement of affected systems.

When a Base Funtion Tray (BFT) is exchanged, the Media Services Card (MSC) should be moved to the replacement BFT. Otherwise system programming will be lost. The BCM will default back to 3 digit, 221 starting DN, if customer data is corrupt.
