Installing the S4810 System 29
The S4810 is designed to support two hot-swappable power supplies with integrated fans that provide the
cooling for the chassis. The S4810 supports AC power supplies with two air-flow directions (Normal and
Reversed). Two power supplies are required for full redundancy, but the system will operate with a single
power supply.
Refer to Chapter 5, Fans for the procedure to replace only a fan module.
The S4810 is orderable as an empty chassis (S4810P) or with an AC power supply. The S4810P-AC/
S4810P-AC-R system comes from the factory with 1 AC power supply and 2 fan modules installed in the
chassis. Power supplies are field replaceable. When running with full redundancy (2 power supplies
installed and running) a power supply unit can be removed an replaced while the other is running without
disrupting traffic.
Components
The following power supply options are available for the S4810:
• AC power supply with integrated fan (Catalog# S4810P-PWR-AC)
• AC power supply with integrated reverse flow fan (Catalog# S4810P-PWR-AC-R)
Chapter 4 Power Supplies
Note: If using a single PSU, you must install a blank plate in the other PSU slot. Force10 recommends
using PSU0, if installing only one power supply.
Danger: To prevent electrical shock, make sure the S4810 is grounded properly. If you do not ground your
equipment correctly, excessive emissions may result. Use a qualified electrician to ensure that the power
cables meet your local electrical requirements.
Attention: Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear
an ESD-preventive wrist or heel ground strap when handling the S4810 and its components.
