System Upgrades
The procedures in this section describe how to remove and replace J6000 workstation
system upgrades. Observe the electrostatic discharge (ESD) precautions and the
prerequisites for installing and removing system upgrades in the next two subsections, as
well as any NOTEs, CAUTIONs, and WARNINGs in each system upgrade procedure.
NOTE If you need to install a new system upgrade, simply follow the procedures for
installing the upgrade in this chapter. (That is, replacement procedures are
the same as those for installing new system upgrades.)
Electrostatic Discharge (ESD) Precautions
To prevent damage to the J6000 workstation, observe all of the following ESD precautions
while performing the system upgrade procedures:
1. Remove all ESD-generating materials from the work area in which you will remove and
replace a workstation’s system upgrade(s).
2. Stand on an ESD (static-free) mat.
3. Wear a grounding wrist strap to ensure that any accumulated electrostatic charge
discharges from your body to ground.
4. Connect all equipment together, including the ESD mat, grounding wrist strap,
workstation, and peripherals.
5. Keep uninstalled printed circuit boards in their protective antistatic bags.
6. Once you have removed printed circuit boards from their protective antistatic bags,
handle the printed circuit boards by their edges only.
