Z SERIES SATADOM REPLACEMENT KIT
This kit includes two mirrored SATADOMs with one USB power connector.
INTRODUCTION
This guide shows how to replace the mirrored SATADOMs on a TrueNAS Z
Series Unied Storage Array. Each node in the array uses a mirrored boot
device congured across two SATADOMs. The SATADOMs included in this
kit are pre-installed with the operating system version and conguration
specied when the kit was ordered. For more information about this kit,
contact [email protected].
PREPARATION
A Philips screwdriver is needed for internal screws. When screws are
removed, place them in a safe place and keep them sorted to make replace-
ment easier during reassembly.

2
NON-HA SYSTEMS WITHOUT FAILOVER
Shut down the TrueNAS array and disconnect both power cables. Make
note of where the network cables are connected and unplug them.
HA SYSTEMS WITH FAILOVER
An HA system with failover has both an active and passive node. For
redundancy purposes, the passive node is on standby and ready to take
over if the active node fails or shuts down.
Before replacing the SATADOMs on an active node, a failover must be
forced by a shut down before physically removing the node. A failover is
not necessary when replacing the SATADOMs on a passive node as it is not
in use.

3
DETERMINE THE ACTIVE NODE
Physically identify each node. Node A is in the top node bay and Node B is
directly below it.
Node A
Node B

4
Use one of these methods to determine which node is the active node.
1. Use the TrueNAS GUI. The icon to the right of the HA Enabled icon will
indicate if that node is Active or Standby.
2. Connect to the node through IPMI, SSH, or a keyboard and monitor
directly attached to the node. When connecting to the node directly, enter
9 in the Console Setup boot menu to access the Shell. Once connected, run
the hactl status command to see if the status of the node is active or
passive.
Finally, use the zpool status freenas-boot command to verify
the health of the SATADOMs. The node that returns any errors has the
SATADOMs that should be replaced.
Before replacing the SATADOMs, use the dmidecode -t1 command to
retrieve the serial number of the node. Record this serial number.
INITIATE FAILOVER
Shut down the active node and wait 60 seconds for the failover to the
standby node to complete.
Note: No failover is necessary when replacing the SATADOMs on a standby
node. Just shut down the node.
After the node is completely powered o, note where the network cables
are connected to that node and unplug them. The node is now prepared
for the SATADOMs to be replaced.

The standard node conguration generally includes one Network Interface
Card (NIC) and one Internal Host Bus Adapter which are both attached to
the PCIe Bus Riser. In this conguration, the network interface card blocks
access to the SATADOM boot device.
Note: the standard node conguration varies by customer.

NODE REMOVAL
On the rear of the TrueNAS array, remove the network cables. Press the
metal latch until the node handle unlocks. Pull the handle down until the
node releases from the node bay.

PART I: REMOVAL OF NODE
COMPONENTS
PCIE BUS RISER REMOVAL
Note: Removal of the PCIe Bus Riser is not required when the Network
Interface Card is not blocking access to the SATADOMs. If the node does
not have a Network Interface Card installed, skip to the SATADOM AND USB
HEADER INSTALLATION section on page 13. When a network interface card
is installed in the node, it and the PCIe Bus Riser must be removed to access
the SATADOM boot device.

9
SLOT COVER RETAINERS REMOVAL
Remove the two slot cover retainer screws and slot cover retainer from the
right side of the chassis.

10
Place the slot cover retainer next to the node with the wires still attached.
Save the screws.
Remove the two screws to detach the left slot cover retainer. Set retainer
and screws aside for use later.

11
PCIE BUS RISER REMOVAL
Remove the 3 PCIe Bus Riser Front Plate screws.

12
Place thumbs on the top corners of the Front Plate and push upward to
partially release the PCIe Bus Riser from the motherboard.
Locate the PCIe Bus Riser release latch. Press on the release latch while
lifting the PCIe Bus Riser to remove it completely.

13
SATADOM AND USB HEADER REMOVAL
The SATADOMs are plugged into the SATA_3 and SATA_5 slots on the
motherboard. Remove each SATADOM individually by depressing the metal
latch while gently pulling upward.
Both SATADOMs are powered from one cable attached to the Front_USB
header on the motherboard. Use thumb and index nger to grip the USB
power connector and gently pull upward to disconnect.

PART II: INSTALLATION OF COMPONENTS
SATADOM AND USB HEADER INSTALLATION
The SATADOM connectors have an L-shaped key and only t into the
motherboard connector one way.
Align the SATADOMs with the SATA_3 and SATA_5 slots on the motherboard.
Press down until each connector clicks into place. The USB header
connector is connected to the Front_USB header on the motherboard.
Make sure the red wires are on the right-hand side of the connector, line up
the pins with the connector, and gently press down until the connector is
fully seated.

15
PCIE BUS RISER INSTALLATION
Skip to to the NODE INSTALLATION section on page 18 unless the PCIe Bus
Riser was removed.
The PCIe Bus Riser has four PCIe Risers that are installed in the PCIE_1,
PCIE_2, PCIE_3, and PCIE_4 slots on the motherboard.
Align the four edge connectors with the PCIe slots on the motherboard.
Press down evenly on the PCIe Bus Riser until the edge connectors click into
place and are rmly seated.

FRONT PLATE SCREW INSTALLATION
Replace the three Front Plate screws to secure the PCIe Bus Riser back in
place.

17
INSTALL SLOT COVER RETAINERS
On the right side of the node, replace the rst slot cover retainer and the
two screws removed earlier.
Replace the second slot cover retainer and the two screws.

18
NODE INSTALLATION
Lift the node to align it with the node bay and slide it into place. Push the
handle up toward the latch until the handle and node lock into place.
Reconnect the network cables to the node. On a single-node non-HA
system, also plug in the power cable and power on the system.
The SATADOM replacement for this node is complete. The system is now
active. Contact support@ iXsystems.com with further questions about
this kit.
