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.
Required hardware
• Replacement Isilon IQ node chassis
• ESD grounded wrist strap
• #2 Phillips screwdriver or #2 JIS driver
Removing the node top panel
The node top panel must be removed to access internal node components, such as DIMM modules, and expansion cards.
1. Remove the chassis retaining screws that secure the node to the rack cabinet.
2. Slide the node out from the rack cabinet to fully extend the slide rails and provide clear access to the node top panel.
Note: To remove the top panel while a node is running, the node must have sufficient cable length or
service loop to fully extend the slide rails without disconnecting the cables.
3. Remove the single screw securing the node top panel.
4. Slide the top panel toward the rear of the node, and lift the top panel off to access the node interior.
Note: Removing the top panel from a node temporarily places the node into a read-only state. The node
returns to a read/write state when the top panel is replaced.
Installing the node top panel
The node top panel must be correctly installed and secure before you power on a node.
1. Slide the top panel back into place.
2. Insert and tighten the top panel screw to secure the top panel to the node chassis.
3. Slide the node back into the rack cabinet.
4. Secure the node to the rack cabinet using the chassis retaining screws.
