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.

Table 1. Stabilization Guidelines

Condition

Stabilization Period

 

 

Desiccant is present.

None

No condensation is on the plastic bag or system

 

surfaces.

 

 

 

Desiccant is present.

4 hours

Condensation is on the plastic bag or on the

 

cabinet or system surfaces.

 

 

 

Desiccant and plastic bag are missing.

8 hours

Condensation is on the cabinet or system

 

surfaces.

 

 

 

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.
