Cabinet Placement; Rack Mounting; Grounding; Fans And Airflow - Dell S4810 Installing Manual

Cabinet Placement

Install the S4810 only in indoor cabinets designed for use in a controlled environment as described in
Selection. Do not install the S4810 in outside plant cabinets.
The cabinet must meet the following criteria:
• Minimum cabinet size and airflow are according to the Electronic Industries Alliance (EIA) standard.

Rack Mounting

When you prepare your equipment rack, ensure that the rack is earth ground. The equipment rack must be
grounded to the same ground point used by the power service in your area. The ground path must be
permanent.

Grounding

Use the S4810 in a Common Bond Network (CBN). You must connect the grounding cables as described
in Chapter 4, Install the

Fans and Airflow

The S4810 fans support two airflow options. Be sure to order the fans suitable to support your site's
ventilation. Use a single type of airflow fan in your system. Do not mix reverse and normal airflows in a
single S4810 chassis.
• Normal—airflow is from the I/O panel to the power supply
• Reversed—airflow is from the power supply to the I/O panel
For proper ventilation, position the S4810 in an equipment rack (or cabinet) with a minimum of
five inches (12.7cm) of clearance around the exhaust vents. When you install two S4810 systems near
each other, position the two chassis at least five inches (12.7cm) apart to permit proper airflow. The
acceptable ambient temperature ranges are listed in
The fan speed increases when the internal temperature reaches 72°C and decreases to normal speed when
the temperature falls to 58°C. The switch never intentionally turns off the fans.
Use the show logging command to see the log messages. For more information, refer to the System Logs
chapters of the FTOS Command Ling Reference Guide for the S4810 System and FTOS Configuration
Guide for the S4810 System.

Power

Use the appropriate power cord with the Z4810 system to connect the chassis to the applicable power
source. An AC power cord is included with the system.
When installing AC systems, follow the requirements of the National Electrical Code, ANSI/NFPA 70
where applicable.
