Chapter 3 Operation of the Magma Expansion
Chassis
3.1 Turn on the server
Before you turn on the server, be aware of the following:
 Turn on the Magma Expansion Chassis before you turn on the server.
 The Magma Expansion Chassis on and off switch is located on the front of the chassis, as well as the back panel.
Turn on both switches and monitor the power status LED indicator.
 Verify that the power status LED indicator is green (the Magma Expansion Chassis is on).
3.2 Normal operation of the Magma Expansion Chassis
During normal operation of the Magma Expansion Chassis, be aware of the following:
 Do not remove the interface cable connecting the server with the Magma Expansion Chassis when the Magma
Expansion Chassis is on.
 Do not turn off the Magma Expansion Chassis during normal operation of the server.
If you fail to perform both this:
 The server operating system may stop unexpectedly with a stop error (blue screen).
 There may be loss of view.
 There may be loss of control if you are running a non-redundant Experion server.
3.3 Turn off the server
Turn off the server first and ensure that this is complete before you turn off the Magma Expansion Chassis. This will avoid
issues where the server operating system may stop responding and/or potential data loss.
