Laser information
The ODD complies with IEC 60825-1 laser class 1.

The ODD contains a light-emitting diode (LED), which under certain
circumstances produces a laser beam stronger than laser class 1.
Looking directly at this beam is dangerous.
Never remove parts of the ODD casing!
Modules with Electrostatic-Sensitive Devices (ESD modules)
ESD modules are identified by the following sticker:
Figure 1: ESD label
I
The ESD label can be different.
When you handle ESD modules, you must always observe the following points:
●
Switch off the server and remove the power plugs from the power outlets
before installing or removing ESD modules.
●
The circuit boards and soldered parts of internal options are exposed and
can be damaged by static electricity. To ensure reliable protection, you must
wear an earthing band on your wrist when working with ESD modules and
connect it to an unpainted, conducting metal part of the server.
●
Any devices or tools that are used must be free of electrostatic charge.
●
Wear a suitable grounding cable that connects you to the external chassis
of the server.
●
Always hold ESD modules at the edges or at the points marked green (touch
points).
