Power Down - Lenovo Storage D1212 Hardware Installation And Maintenance Manual

The unit identification number is not set before the first system power on. The display is set to "00" (flashing).
The enclosure continues to power up even if the unit identification number is not set.
To set the unit identification number:
1. Press and hold the Input switch on the ops panel for a period of five seconds. The left-hand digit flashes.
2. Press and release the Input switch to increment the number until the required digit is reached.
3. Press and hold the Input switch for a period of five seconds. The right-hand digit flashes.
4. Press and release the Input switch to increment the number until the required digit is reached.

to "99" are valid.
Once a unit identification number is set, it is stored in the midplane VPD by the Enclosure Management
software and will appear when the enclosure is next powered on. In a situation where the VPD cannot be
read, or where there is no enclosure management (no ESMs, or a single module with management failure) the
enclosure will display "00".
