Replace appliance components
This section describes the procedures for replacing appliance components.
Replacing the power supply unit (PSU)
This appliance has two main redundant, hot-pluggable Power Supply Units (PSU) to support the entire system. The following steps cover how to replace a PSU.
- Unplug the power cord from the PDU and then from the PSU.
- Pull down the PSU handle and squeeze the thumb latch towards the handle.
- Holding both handle and thumb latch, pull unit towards you until it is free of the PSU slot, as shown in the following figure.
- To replace a PSU, insert unit into a free PSU slot.
- Push unit into slot as far as it will go. You will hear a click when the PSU is locked in place.
- Attach power cord to the PSU and then to the PDU.

Remove and install a drive
Each hot-pluggable 2.5” drive is mounted on a drive carrier assembly with an ejection lever for quick installation and removal.
- To remove the drive you are replacing or remove a blank carrier from the drive bay:
- Push the colored ejector lever button. The lever will automatically unlatch. Pull the drive
carrier out of the drive bay, as shown in the following figure.
Figure 2. Replacing a drive 
- Grasp the drive carrier firmly and slide it out of the drive bay.
- Push the colored ejector lever button. The lever will automatically unlatch. Pull the drive
carrier out of the drive bay, as shown in the following figure.
- To install a drive follow this process:
- With the ejector lever on the drive carrier open, insert the assembled drive carrier into the
empty drive bay in front of the chassis, as shown in the following figure.
Figure 3. Installing a drive in the front panel 
- Push the carrier all the way into the slot then close the drive lever to lock it in place.
- Repeat the previous steps to assemble and install all other drives into the empty front drive slots.
- With the ejector lever on the drive carrier open, insert the assembled drive carrier into the
empty drive bay in front of the chassis, as shown in the following figure.
Remove and install a fan
This section describes the process for removing and installing fans.
The following steps cover how to remove a fan:
- Open fan cover (see the section on Removing or Replacing the Fan Cover ).
- Remove the fan unit by grasping it by the finger hold tabs, as shown in the following figure.
- Pull the unit straight up until it disengages from its slot.

- To install a fan, follow these steps:
- Grasp the fan unit by the finger holds and place it straight down in its slot, as shown in the following figure.
- Make sure the fan connector is seated properly in the connection socket on the slot to secure it.
- Replace the fan cover (see the section on Removing or Replacing the Fan Cover).

Remove and install PCIe riser cards
This section describes the process replacing and installing PCIe riser cards.
To remove a card, follow these steps as shown in the following figure.
- Power off and unplug AC cords.
- Remove any cables that may be attached to the ports of the card.
- Grasp the riser and pull it straight up and out of the chassis.
Figure 7. Removing a riser card 
- From the edges of the card, carefully pull it straight out of the PCIe slot and free the
connector ports from the riser assembly, as shown in the following figure.
Figure 8. Replacing a riser card 
- To install PCIe riser cards, follow these steps as shown in the following figure.
- Power off the system and disconnect all external cables and power cords. 2.
- Install the card into the riser by inserting the connector ports through the riser faceplate (1)
and aligning the key slot and gold fingers of the card to the PCIe slot.
Figure 9. Installing a riser card 
- Press the card all the way into the slot. Make sure that the gold fingers are fully engaged.
- Align the riser bracket with the rear chassis and press it down until it is secured to the
chassis as shown in the following figure.

Replacing the CMOS Battery
If the server no longer automatically displays the correct date and time, you many need to replace the battery that provides power to the real-time clock.
To reduce the risk of personal injury: do not expose the battery to temperatures higher than 60°C (140°F) and do not dissemble, crush, puncture, short external contacts, or dispose of in fire or water.
Replace only with the proper replacement designated for this product.
Recycle or discard the battery as instructed by local regulations.
The following steps cover how to remove the CMOS battery.
- Power off the system and disconnect all power cords and necessary external cables.
- Push the retainer clip towards the back of the battery socket. The battery will pop out slightly
from the socket, as shown in the following figure.
Figure 11. Releasing CMOS battery from motherboard 
- Grasp the battery and remove it from the socket as shown in the following figure.
Figure 12. Removing the battery 
- To replace the CMOS battery, follow these steps:
- Push the retainer clip towards the back of the battery socket.
- Gently insert battery into the socket and inside the retaining clip and push it into the socket
until fully seated, as shown in the following figure.
Figure 13. Replacing CMOS battery 
- Reattach all power cords and necessary external cables, then power on the system.Note: Make sure you note the orientation of the polarity of the battery before you remove it so that you can insert it with the same orientation, as shown in the following figure.
