Replacement or system upgrades

This chapter provides detailed instructions on modifying your device hardware (e.g.
installing boards or drives).
Read the supplied documentation before installing any new drives or boards.

Information about boards

Take care with the locking mechanisms (catches and centering pins) when you are replac-
ing boards or components on boards.
To prevent damage to the board or the components and conductors on it, please take care
when you insert or remove boards. Make sure expansion boards are inserted straight.
Never use sharp objects (screwdrivers) for leverage.

Boards with electrostatic sensitive devices (ESD) are identified by the label shown.
When you handle boards fitted with ESDs, you must, under all circumstances, observe the
following points:
•
You must always discharge static build up (e.g. by touching a grounded object) before
working.
•
The equipment and tools you use must be free of static charges.
•
Always hold boards with ESDs by their edges.
•
Never touch pins or conductors on boards fitted with ESDs.
