Installing the S50 System 11
This chapter describes requirements and procedures to install your S50 system. This chapter covers the
following topics:
•Site Selection
•Cabinet Placement
•Rack Mounting
•Fans and Airflow
•Power
•Storing Components
For detailed S50 specifications, refer to Chapter 6, S50 Specifications, on page 35.
Site Selection
Make sure that the area where you install your S50 chassis meets the following safety requirements:
• Near an adequate power source. Connect the system to the appropriate branch circuit protection as
defined by your local electrical codes.
• Environmental temperature between 32° – 122°F (0° – 40°C).
• Relative humidity that does not exceed 95% non-condensing.
• In a dry, clean, well-ventilated and temperature-controlled room, away from heat sources such as hot
air vents or direct sunlight.
• Away from sources of severe electromagnetic noise.
• Positioned in a rack, cabinet, or on a desktop with adequate space in the front, rear, and sides of the
unit for proper ventilation, and access.
Chapter 2 Site Preparations
Note: Install the S50 into a rack or cabinet before installing any optional components.

12 Site Preparations
Cabinet Placement
The cabinet must meet the following criteria:
• Minimum cabinet size and airflow are according to the EIA standard.
• Minimum of 5 inches (12.7 cm) between the side intake and exhaust vents and the cabinet wall.
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.
Fans and Airflow
For proper ventilation, position the S50 chassis in an equipment rack (or cabinet) with a minimum of five
inches (12.7 cm) of clearance around the side intake and exhaust vents. When two S50 systems are
installed side by side, position the two S50 chassis at least 5 inches (12.7 cm) apart to permit proper
airflow. The acceptable ambient temperature ranges are listed in Environmental Parameters on page 35.
As listed in Table 3, “Status Panel LED Display,” on page 10, the front panel of the S50 has both a fan
status LED and a temperature LED. The fan status LED is green when all of the six fans are operating
normally, amber when any are not operating normally. The fan speed increases when the temperature of
either of the two sensors reaches 72 degrees C, and decreases to normal speed when the temperature falls
to 57 degrees C. The switch never intentionally stops managing traffic.
The temperature status LED is also green when the switch is operating within required temperature
parameters. The LED turns amber when either of the two temperature sensors indicates an out-of-range
temperature, and returns to green when the temperature returns to normal. SFTOS logs a temperature
warning message when a temperature of 77 degrees C is reached, and logs another message when the
temperature returns to normal.
Use the show logging buffered command to see the log messages. For details, see the Syslog chapters
of the SFTOS Command Reference or SFTOS Configuration Guide.
In a stack, each unit has its own temperature monitoring and control. Status logging is identified by unit in
the system log.
Fan replacement is not offered as an option in the field.

Installing the S50 System 13
Power
Use the power cord shipped with the S50 chassis to connect the chassis to the AC power outlet.
Storing Components
If you do not install your system and components immediately, Force10 Networks recommends that you
properly store the S50 and all optional components until you are ready to install them.
Follow these storage guidelines:
• Storage temperature should remain constant ranging from -4° to 158° F (-20°C to 70° C).
• Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
• Store in a dust-free environment.
Caution: The power supply cord is used as the main disconnect device; ensure that the
socket-outlet is located/installed near the equipment and is easily accessible.
Warning: Electrostatic discharge (ESD) damage can occur when components are mishandled.
Always wear an ESD-preventive wrist or heel ground strap when handling the S50 and its
accessories. After you remove the original packaging, place the S50 and its components on an
antistatic surface.

14 Site Preparations

Figure 2). If you have purchased the backup power option, Force10 recommends that you install the DC
power module before installing the unit in a rack, and that you connect the module to its AC-to-DC
converter before powering up the S50. See Installing Backup Power on page 27.
Tabletop Installation
The S50 can be positioned on a stable tabletop. Keep the following in mind when using a tabletop for your
S50:
• Ensure that your tabletop is stable and can handle the weight of the S50 or a stack of S50s, along with
any added backup power supplies.
• Position the table so that there is proper ventilation and easy access to power outlets.
Rack or Cabinet Installation
The S50 provides three rack-mounting methods:
•Two-Post Rack Mounting
•Four-Post Rack-mounting with Threaded Rails
•Four-Post Rack-mounting with Cage Nuts
3. Remove the 10-Gigabit module from its packaging and slide the module into the 10-Gigabit slot.
4. Secure the captive screws on either side of the module.
5. Connect the S50 to its power source and power up the S50.
