MAP2341 Codes on the DC-UPS DSU status display

The DC-UPS status display on the front of the DC-UPS indicates status and error conditions. Error conditions that are displayed create serviceable events. Use the serviceable events to guide the repair.

MAP2341 Section-1

Procedure

  1. The DC-UPS is displaying an error code, which is defined in Table 1. A serviceable event is created unless the DC-UPS is in a rack that is not yet fully installed.
  2. During DC-UPS power on, the DC-UPS status display shows the DC-UPS firmware level and DC-UPS identification. DC-UPS firmware level is also available through the management console utilities to display the installed code levels.
    The following sequence of characters is displayed:
    XX > yy > zz > Du
  3. After DC-UPS power on, the status display is normally blank.
