Opening and Closing the Netgate 8300 Chassis

Some tasks may require opening up the chassis on the Netgate 8300 to access internal components. This document covers all steps required to open and close the chassis.

Warnings and Precautions

Danger

Anti-static protection must be used throughout this procedure.

Danger

Take all appropriate precautions and exercise care when handling the exposed system board and add-on cards. There are many delicate components which can be damaged during this process. Damage caused via physical contact and electrostatic discharge while performing this installation is not covered by the warranty.

Warning

This device includes an intrusion detection sensor which operates even when the device is without power.

Opening the case on this device triggers an intrusion alarm which is logged by the BMC and is visible in the IPMI sensors. This alarm must be reset manually as described in Re-arm the Chassis Intrusion Switch.

When the intrusion alarm is active the fans run at a fixed speed of around 8500 RPM. Resetting the intrusion sensor alarm returns the fans to their profiled speed.

Required Tools and Hardware

Opening and closing the Netgate 8300 chassis requires the following tools and hardware:

• Phillips screwdriver

• Anti-static grounding strap and anti-static mat for handling the 8300 system
