IMPORTANT SAFETY INSTRUCTIONS

(Continued from previous page)

21. Damage Requiring Service

Unplug this product from the wall power out- let and refer servicing to qualified service personnel under the following conditions:

a. If the power-supply cord or plug is damaged.

b. If liquid has been spilled, or objects have fallen into the product.

c. If the product has been exposed to rain or water.

d. If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions, as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation.

e. If the product has been dropped or the cabinet has been damaged.

f.If the product exhibits a distinct change in performance.

Caution: Refer all servicing to qualified service personnel.

22. Servicing

Caution: These servicing instruc-

tions are for use by qualified service personnel only. To reduce the risk

of electrical shock, do not perform any servicing other than that described in the operating instructions unless you are qualified to do so.

23.Replacement Parts

When replacement parts are required, be sure the service technician uses replacement parts specified by the manufacturer or that have the same characteristics as the original parts. Unauthorized substitutions may result in fire, electric shock, or other hazards.

24. Safety Check

Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating condition.

PCS100R Rack Installation (also see pages 9 and 10)

To install the PCS100R in a rack:

•Carefully slide the PCS100R into a standard 19-inch equipment rack.

•When mounted in the rack, make sure appro- priate hardware is used. ALL FOUR MOUNT-

ING SCREWS MUST BE USED.

•This equipment is not designed to support other devices. Do NOT stack other equipment on the top of the PCS100R.

•Rear cabling must be dressed and supported so that the weight of the cabling is not a strain on the PCS100R connectors.

•MOUNTING OF THE EQUIPMENT IN THE RACK SHOULD BE SUCH THAT A HAZARD- OUS CONDITION IS NOT ACHIEVED DUE TO UNEVEN MECHANICAL LOADING.

Rack-mount Considerations

A. Elevated Operating Ambient

If installed in a closed or multi-unit rack assembly, the operating ambient tempera- ture of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer (see “Specifications” information in this document).

B. Reduced Air Flow

Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Do NOT stack other equipment on the top of the PCS100R unit.
