Stabilizing the Systems
If temperature and humidity changes have been extreme during
transit, the cabinet and systems might develop condensation.
Therefore, before you install and power on the systems, you must
inspect them and the cabinet for condensation and, if necessary,
stabilize the systems. To stabilize the systems, let the cabinet
stand, unpacked and without its plastic wrap, in the open air of an
office environment.
1. Inspect each cabinet and system for condensation. Use the
guidelines in
Table 1 to determine if a system requires a
stabilization period before you install it and power it on.
2. After the stabilization period, if you still notice signs of
condensation inside or outside the cabinet, allow an additional
stabilization period of two hours. Repeat the two-hour period,
if necessary, until there are no signs of condensation. Then,
continue to the next step.
3. Remove the desiccant bags and the cardboard tray in which
they were shipped, if these items are still present.
