L1 Controller Error Messages
Table 15-2 lists error messages that the L1 controller generates and displays on the L1
display. This display is located on the front of all bricks (except the TP900 and D-brick2
storage modules).
Note:
In Table 15-2, a voltage warning occurs when a supplied level of voltage is below
or above the nominal (normal) voltage by 10 percent. A voltage fault occurs when a
supplied level is below or above the nominal voltage by 20 percent.
