Node chassis
The node chassis contains all of the components that make up an Isilon node.
General ESD guidelines
Always follow electrostatic discharge (ESD) prevention procedures when removing and replacing cards, memory, and other
system components. You must use a wrist strap, attached to the node chassis, for grounding.

Replacing a 108NL chassis
If you are replacing an IQ 108NL chassis, refer to separate documentation specific to that model.
Attention: Do not use this procedure to replace a failed 108NL chassis. If you are replacing a failed 108NL, refer
to the document titled Replace an IQ 108NL Node using a 3/4 Chassis.

Replacing a node by using a 3/4 chassis
If you are unable to smartfail a node before removing the node from a cluster, you can replace the failed node using a
3/4 chassis while maintaining data integrity. This procedure is supported only for nodes that are running OneFS 5.5.3
and later.
Prerequisite: Contact Isilon Technical Support to obtain a replacement chassis before beginning this procedure.
Important: A warning label is affixed to the back of each Isilon node chassis stating that you must disconnect
power before servicing the node. However, this procedure requires that adequate power be available to the
NVRAM card in the event that a file system journal transfer is required. To ensure this power availability, you
must keep both the failed node and the replacement node connected to power (but not powered on) during the
NVRAM card transfer. Because all high-current supplies are turned off during this procedure, risk of electric
shock is mitigated.
1. Clear a work area large enough to place two Isilon nodes side-by-side.
Note: Ensure that there is an outlet available for powering on the nodes.
2. Unpack the replacement chassis and immediately connect it to power.
Do not discard the shipping container and packaging. You will use the container and packaging to return the failed
node to Isilon.
