3952 or 3948 Tape Frame details

Edit online

This topic describes the key characteristics of the 3952 Tape Frame.

Note: Any lock on the 3952 Tape Frame prevents access to the TS7700 Emergency Power Off (EPO) switch. If a lock (FRU 12R9307) is installed on the 3952 Tape Frame, an external EPO switch or circuit breaker must be installed near the TS7700 to allow an emergency shutdown. Additionally, the emergency contact label that is included with the Installation Instruction, F06F0x requires RPQ 8b3669 (Front/Rear and Side Panel Locking Procedure), PN 00VJ478, must be completed and affixed to the 3952 Tape Frame door in an immediately visible location. This label must clearly indicate the location of the external EPO switch or circuit breaker.

If a lock is installed on the 3952 Tape Frame and the original key is not available, any 3952 Tape Frame key can be used to open the lock. If no frame key is available and immediate access is required to get inside the frame, you must contact a locksmith to open the lock. If the key is still unavailable after the lock is opened, you can contact your IBM service representative to order a new lock and key set (FRU 12R9307).
