Replace a Battery

The lithium coin-cell battery in the Pilot maintains system time when the Pilot is powered off and a time server is unavailable. The battery also powers the CMOS BIOS system settings of the Oracle FS System. Replace the battery if the Pilot fails to maintain proper time or the battery gets discharged due to wear and tear.

Prerequisites:

Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Ensure you have a screwdriver or any kind of sharp pointed object.

Each Pilot battery has a battery located on the Pilot motherboard. Batteries are customer replaceable units (CRUs) and are not hot-serviceable. Replacing the battery requires you to power down the Pilot. The following figure identifies the location of the battery inside the Pilot motherboard.

Note: The battery can be accessed only after removing the cover over the Pilot chassis.

Note: Ensure that all power is removed from the Pilot before removing or installing the battery. You must disconnect the power cords from the Pilot before performing these procedures.

Identify the Pilot component for replacement

Locate the failed component by checking the status of the component LEDs.
You can also use Oracle FS System Manager (GUI) to view the status. From the GUI, navigate to System > Hardware and then select the chassis type of interest.
From the GUI, prepare the system for component replacement.

Power off the Pilot

Notify affected users that the Pilot will be powered off.
Ensure that the host of the Pilot on which the replacement procedure must be performed is powered off.

Slide the Pilot into service position

Slide the Pilot chassis fully forward until the slide rails lock into position.

When Guided Maintenance prompts you to remove the component, pull the flip handles at front of the Pilot and start sliding the Pilot out of the rack.
Caution
Deploy any rack anti-tilt mechanism before releasing the release buttons and extending the Pilot.

Note: The slide-rail locks are located behind the flip-down handles on the front of the Pilot chassis. The slide-rail locks are released when the flip-down handles are pulled down. The slide lockout release tab must be released to push the Pilot chassis back into the rack.

Open Pilot fan door

Press the two fan door release tabs simultaneously forward and swing the Pilot fan door to the open position.
Note: Servicing the Pilot fan modules and other components located in the front of the Pilot, such as the front indication module (FIM) and the disk backplanes, require that the fan door be opened. It is also easier to remove the Pilot’s top cover if you open the fan door first.

Open Pilot top cover

Press down on the push button on the Pilot top cover to release the top cover and use the recessed areas to slide the top cover toward the back of the Pilot about 0.5 inches (12.7 mm).
Caution
Before removing the top cover of the Pilot, power off the Pilot using Guided Maintenance. Removing the Pilot top cover before powering off the Pilot might cause damage to the software image on the Pilot.

Tip: Slide out the Pilot top cover by pressing down on the grooves located on both sides of the cover.

Remove the failed Pilot battery

Remove the battery by placing your finger or a pointed tool like a screwdriver under the battery on the side nearest to the back of the Pilot and gently lifting the battery out of the retainer.

Place the battery on an antistatic mat.
Note: Replacing a battery usually resets the CMOS settings to a default value. Export the BIOS settings to an XML file from the ILOM prior to battery replacement and then import the settings in the BIOS when the battery replacement is completed.

Insert the failed Pilot battery

Unpack the component from its shipping carton.
Note: Place the component on an antistatic mat if it must be set aside for any reason.
Press the replacement battery into the battery retainer with the positive side (+) facing upwards.

If the Pilot is configured to synchronize with a network time server using the Network Time Protocol (NTP), the Oracle ILOM clock is reset as soon as the Pilot is powered on and connected to the network. Otherwise, proceed to the next step.
If the Pilot is not configured to use NTP, reset the Oracle ILOM clock using the web interface. You can also reprogram the BIOS Setup utility to reprogram the host clock.

Close Pilot top cover

Place the top cover of the Pilot onto the chassis.
Tip: Place the top cover down so that it hangs over the back of the Pilot by about 13 mm (0.5 inches) [1] and the side latches align with the slots in the sides of the Pilot chassis.

Note: There are three latching tabs on the sides of the Pilot top cover, two on the right side and one on the left side when viewing the Pilot from the front. There is also a latch on the underside of the top cover in the front left corner near the release button.
Check both sides of the Pilot chassis to ensure that the four corners of the top cover are fully down and flush with the chassis.
Note: If the cover corners are not flush with the Pilot chassis, slide the cover towards the back of the chassis until you can position the cover correctly.

Note: If the top cover is not correctly positioned before attempting to slide the cover forward, the internal latch that is on the underside of the cover might be damaged.
Gently slide the top cover along the grooves of the Pilot by pressing down on either side of the top cover until it locks into place and you hear an audible click.

Close the Pilot fan door by pressing the two release tabs on both sides of the fan door until it locks into place.

Slide the Pilot into rack position

Simultaneously pull and hold the two release tabs, one on each side of the Pilot, toward the front of the Pilot while you push the Pilot into the rack.
Figure 9 Location of the Pilot release tabs

Note: As you push the Pilot into the rack, verify that the cable management arm (CMA) retracts without binding.

Note: To pull the Pilot release tab, place your finger in the center of the tab, not on the end, and apply pressure as you pull the tab toward the front of the Pilot.
Continue pushing the Pilot into the rack until the slide-rail locks on the front of the Pilot engage the slide-rail assemblies.
Note: The Pilot locks into the rack position with an audible click.

Power on the Pilot

Reconnect the power cords to the Pilot.
Note: After the power cords are connected, the green SP LED and the OK LED both start to blink.

Note: Do not turn on the power to the Pilot host immediately. The power on the Pilot host is turned on only after updating the Pilot BIOS. Turning on the power to the Pilot host early can prevent the Pilot from booting after the Pilot BIOS is updated.

Verify the Pilot component status

From Guided Maintenance, verify that the status is Normal.
You can also verify the status by navigating to System > Hardware and then selecting a chassis. The Overview page for the selected chassis lists the status of each component.
Note: The Controller status will be visible several minutes after being powered on.
Review the status of the LEDs to confirm a status of Normal.
