1.7.1 Removing the transport lock for the hard disk
Note
Not every device has a hard disk transport lock.
To enhance the ruggedness of the SIMATIC Panel PC 577 during shipping, the device is
fitted with a transport lock for the hard disk. This comprises two knurled screws that clamp
the hard disk to prevent undesirable vibrations. The hard disk transport lock is located on the
top of the SIMATIC Panel PC 577 and is marked with an adhesive label. When shipped, the
transport lock is locked. Before you switch on the device for the first time, you must remove
the transport lock for the hard disk.
