3:1 UPS unit operating in bypass mode, no output
The 3:1 UPS units require a precise installation as the Maintenance Bypass Panel (MBP) must
always be installed with these UPS units. Verify that the installation is correct. See
Phase HotSwap MBP installation and connection
During start up the UPS logs 0x60D
Issue
During UPS start up the error 0x60D is logged. The UPS may issue a "No battery" and the
battery test will end with the error, "Failed. No battery".
Solution
The battery is not connected to the UPS – there is a DC breaker that needs to be engaged, the
DC voltage cable to the UPS and the battery detection cable. All 3 are needed to be correct for
the battery to be recognized.
0x60D means that the unit was shut down before the EEPROM was fully written – to clear this
error, the Battery must be connected. Once the battery is recognised and connected,
disconnect the input utility, wait until the LCD goes blank and then disconnect the battery (DC
Breaker). The EEPROM will write the checksum and the 0x60D will be cleared.
Additional information
This issue is a configuration fault on the 100 Mbps Network Management Card.
