3. Remove the blank panel from the appropriate vacant bay

(A or B).

4. Align and insert the replacement ECB into the vacant bay

until the lever engages the enclosure (see Figure 5).

5. Lift the lever upward until the lever locks.

6. If enclosure power is applied, verify that the LED displays

a Charge Test state (see Figure 7 for LED locations and

Table 1 for the proper display state).

7. Following ECB initialization, verify that the LEDs display

either a Charging or Charged state (see Figure 7 for LED

locations and Table 1 for the proper display state).

8. Press the release tab on the old ECB, and then pivot the

lever downward.

9. Remove the old ECB from the enclosure.

LED Display ECB State Definition

Startup: Checking temperature and

voltage. If this state persists for more

than 10 seconds, then a temperature

fault exists.

Backup: If power is removed, a low duty

cycle F

LASH indicates normal operation.

Charging: The ECB is charging the

battery.

Charged: The ECB battery is charged.

Charge Test: The ECB is ascertaining

whether the battery is capable of

holding a charge.

Temperature Fault Indications:

• If this indication displays, the ECB

battery charging is suspended until

the temperature fault has been

corrected.

• If this indication displays, the ECB

battery is still capable of backup.

ECB Fault: Indicates the ECB has

faulted.

Battery Fault: The ECB determined the

battery voltage is incorrect or the battery

is missing.
