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.
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.
For safety, before opening the case, the Netgate 8300 must be completely
disconnected. This includes power, network cables, USB cables, serial console
cables, and any other external cables or devices connected to the Netgate 8300.
Danger
Reminder:
Anti-static protection must be used throughout this procedure.
Any hardware damage incurred during this procedure is not covered by
the hardware warranty.
Turn power off to the unit by changing the power switch on the rear of the
unit to the off position.
Opening the case triggers the intrusion alarm sensor, even when the device is
removed from power. The intrusion alarm causes the fans to run at a higher fixed
speed until the sensor is re-armed.
