– Protect the disks from exposure to heat and direct sunlight.
Laser information
The optical disk drive complies with IEC 60825-1 laser class 1.

CAUTION!
The optical disk drive contains a light-emitting diode (LED), which under
certain circumstances produces a laser beam stronger than laser

Modules with Electrostatic-Sensitive Devices (ESD modules)
Modules with electrostatic-sensitive devices 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.
