Observe the UPS control panel Fault LED (red). See Figure 2.
Select the condition that applies:
- OFF. Normal state, go to step 6.
- ON. Internal or environmental fault. Go to step MAP2870 Section-3 Fault LED on.
- Flashing. Go to step MAP2870 Section-4 Fault LED flashing.
Is the Output status LED (green) lit solid? See Figure 2.
- Yes, go to step 7.
- No, go to MAP2870 Section-5 Output status LED off.
Are the LOAD 1 and LOAD 2 icons lit? See Figure 3.
- Yes. The fault condition is not present. Exit this MAP.
- No. MAP2870 Section-6 LOAD1, LOAD2 icon off.

At the rear of the rack, locate the UPS Input breaker. See Figure 4.

Figure 4. Locations, UPS, rear
Is the UPS Input breaker tripped?
- Yes, go to MAP2890 UPS overcurrent (Model 983) .
- No, go to MAP2880 Loss of AC input to a single UPS (Model 983).

When the Fault LED is on, an error code is displayed.

The following error codes can be displayed. These are provided for general information only. The UPS is not repairable.

Table 1.
Error code	Meaning
E11	Charger fault
E12	Fan fault
E13	Over temperature
E14	+/- DC bus high / low
E16	Inverter fault
E18	DC-DC fault
E19	Abnormal output/inverter voltage
E21	O/P short
sd0	Emergency shutdown
sd1	Remote shutdown
sd2	Shutdown After shutdown enabled
sd3	Battery Save shutdown
sd4	Battery low shutdown

There are two faults that can cause the Fault LED to flash:
1. Battery related fault. See Figure 5. Go to step 2.
2. UPS overcurrent fault. See Figure 6. Go to step 3.
  
  Figure 5. UPS control panel battery icon
  
  Figure 6. UPS control panel overload icon
Battery related fault. Four conditions can cause this fault:
- Battery is not physically installed. Physically install and connect the battery.
- Battery cable is not connected and needs to be connected.
- Battery is failing and needs to be replaced.
- UPS is failing and needs to be replaced.
1. If there is a related open serviceable event, use that to correct the battery problem.
2. If there is not a related open serviceable event, use MAP1230 Replace a FRU without using a serviceable event.
UPS overcurrent fault.
1. If there is a related open serviceable event, use that to correct the battery problem.
2. If there is not a related open serviceable event, exit this MAP and go to MAP2890 UPS overcurrent (Model 983).

The AC input icon is on. The Output status LED is off.

The UPS is in standby mode.
The J3-J8 output connectors do not have power.
Exit this MAP and do a pseudo repair of the PPS. When directed to replace the UPS, reuse the existing PPS. If the same failure occurs, replace the UPS with a new UPS.

The AC input icon is on and the Output status LED is on.
Select the following condition that applies.
- Both the LOAD1 and LOAD2 icons are not lit. Go to step 2.
- Only one icon (LOAD1 or LOAD2) is lit. Go to step 3.
The LOAD1 and LOAD2 icons are not lit.

Note: This is the expected state of the LOAD1 and LOAD2 icons when the UPS was powered off by the UPS control panel OFF button (see Figure 2), and then input power to the UPS was lost. When the input power is restored, the UPS returns to the state it was in before loss of power.
1. Press the UPS control panel ON button for three seconds and release it after you hear one beep.
2. Are the UPS LOAD1 and LOAD2 icons both lit?
  - - Yes. The UPS is now in a normal state. Exit this MAP and check for open related serviceable events.
    - No. Exit this MAP and replace the failing UPS.
Only one icon (LOAD1 or LOAD2) is lit. Power off and then power on the UPS.
1. Press the UPS control panel OFF button for three seconds and release it after one beep.
2. Press the UPS control panel ON button for three seconds and release it after one beep.
Are the UPS LOAD1 and LOAD2 icons both lit?
- Yes. The UPS is now in a normal state. Exit this MAP and check for open related serviceable events.
- No. Exit this MAP and replace the failing UPS.
