Unit identification number
After a unit identification number is set, it is stored in the midplane VPD by the Enclosure Management
software and appears when the enclosure is next powered on.
How to set the unit identification number
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 on even if the unit identification number is not set.
To set the unit identification number, do the following steps.
1. Press and hold the Input switch on the ops panel for 5 seconds. The left digit flashes.
2. Press and release the Input switch to increment the number until the wanted digit is reached.
3. Press and hold the Input switch for 5 seconds. The right digit flashes.
4. Press and release the Input switch to increment the number until the wanted digit is reached.
5. Press and hold the Input switch for 5 seconds to finish setting the number. Values of “01” to “99” are
valid.
In a situation where the VPD cannot be read, or where there is no enclosure management (compute
module management failure) the enclosure displays “00”.
Other uses
The unit identification number can also have the following uses:
v Error codes.
v Unit location identifier. This function sets the display to flash (3 seconds on, 1 second off) until it is
stopped, either through SES or by pressing the Input switch.
