Installing ServerIron ADX modules in a running system
2
Uninstalling a Fan module
It is not generally recommended for the Fan module to be removed while a ServerIron ADX 4000,
ServerIron ADX 8000 or ServerIron ADX 10000 is in operation. With the Fan module removed, a
syslog message indicating that the fan is not present will be sent and the system will rapidly
heat-up. If the ServerIron ADX modules rise above the shutdown thresholds, they are gracefully
shutdown as described in the following:
• Interface modules are shutdown individually as they exceed their threshold temperature which
disrupts any traffic that transits that module.
• When the temperature of the active management module exceeds its threshold, the entire
ServerIron ADX chassis is shutdown.
• When the temperature of a Switch Fabric module is exceeded, it is shutdown which disrupts
operation of the entire ServerIron ADX.
You can however, briefly remove a Fan Tray from an operating ServerIron ADX 4000, ServerIron ADX
8000 or ServerIron ADX 10000 for a few seconds and replace it with a new one before the
shutdown temperature thresholds are reached.
Uninstalling a Power Supply
Power Supplies can be removed while a ServerIron ADX 4000, ServerIron ADX 8000 or ServerIron
ADX 10000 is in operation as long as the minimum number are still installed and active in the
chassis.
• For the ServerIron ADX 4000, one power supply is required and one additional power supply
can be installed to provide a backup.
• For the ServerIron ADX 8000 or ServerIron ADX 10000, two power supplies are required and
two additional power supplies can be installed to provide a backup.
Redundant power supplies can be added during operation.
When a power supply is removed or added during operation, messages are sent to the console and
logged indicating that the supply is present or not present in the system.
Installing ServerIron ADX modules in a running system
This section describes the issues and considerations that you must follow when installing various
module type into a running ServerIron ADX chassis.
Installing a management module in a running system
You can install a Standby Management module in a running system without any service disruption.
When the Standby Management module in inserted in its designated slot, it is automatically
detected and brought online.
