Power Supplies

The S60 system is designed to support two hot-swappable power supply units (PSUs) with integrated

fans that provide the cooling for the system. There are two types of power supplies (AC or DC) and there

are two airflow directions (normal and reverse). Two PSUs are required for full redundancy, but the

system will operate with a single PSU. You can equip one of the PSU bays with a fan-only module.

For the procedure to replace only a fan module or fan filter, refer to

Chapter 5, Fans and Filters

You can order the S60 system as an empty chassis or with either AC power (

Figure 4-1

) or DC power

(

Figure 4-2

). Both PSU types are field replaceable. When running with full redundancy (two PSUs

installed and running), you can remove and replace one PSU while the other PSU is running without

disrupting traffic.

WARNING: To prevent electrical shock, ensure the S60 system is grounded properly. If you do not ground

your system correctly, excessive emissions may result. Use a qualified electrician to ensure that the power

cables meet your local electrical requirements.

WARNING: Electrostatic discharge (ESD) damage can occur if the components are mishandled. Always

wear an ESD-preventive wrist or heel ground strap when handling the S60 system and its components.
