Installing the S55 System 9
Introduction
The Force10 Networks S55 is a high performance, high capacity, low cost, stackable, Layer 2 switch/Layer
3 router that supports 44 built-in 10/100/1000 Base-T ports, four SFP (small form-factor pluggable) ports,
and two optional module slots, and optional 12G stacking module. The S55’s PSU (Power Supply Unit)
side (Figure 1) contains the Power Supply Units (PSUs), and optional module slots. As shown in Figure 2,
the S55’s I/O (Input/Output) side contains the 44 ethernet ports, the SFP ports, the management ports and
the displays for alarms and stacking identification.

Installing the S55 System 15
The S55 is suitable for installation as part of a Common Bond Network (CBN). It can be installed in
• network telecommunication facilities
• data centers
• other locations where the National Electric Code (NEC) applies
This chapter covers the following topics:
•Site selection
•Cabinet placement
•Rack mounting
•Grounding
•Fans and airflow
•Power
•Storing components
For detailed S55 specifications, refer to Chapter 7, S55 Specifications.
Site selection
Force10 Networks’ equipment is intended for installation in restricted access areas. A restricted access
area is one in which access can only be gained by service personnel through the use of a special tool, lock,
key or other means of security and access is controlled by the authority responsible for the location.
Make sure that the area where you install your S55 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° to 104°F (0° to 40°C).
• Relative humidity that does not exceed 85% non-condensing.
Chapter 2 Site Preparations
Note: Install the S55 unit into a rack or cabinet before installing any optional components.

16 Site Preparations
• 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 or cabinet, or on a desktop with adequate space in the front, rear, and sides of the
unit for proper ventilation, and access.
Cabinet placement
The S55 should be installed only in indoor cabinets designed for use in a controlled environment as
described in the Site Selection heading. The S55 should not be installed in outside plant cabinets.
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 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.
Grounding
The S55 is for use in a Common Bond Network. You must connect grounding cables as described in
Chapter 3, Install the S55.
Fans and airflow
The S55 system fans support with 2 air flow options. Be sure to order the fans suitable to support your
site’s proper ventilation. Use a single type of fan in your system. Do not mix Reverse and Normal airflows
in a single chassis.
• Normal is airflow from I/O panel to power supply
• Reversed is airflow from power supply to I/O panel
For proper ventilation, position the S55 chassis in an equipment rack (or cabinet) with a minimum of five
inches (12.7 cm) of clearance around exhaust vents. When two S55 systems are installed near each other,
position the two chassis at least 5 inches (12.7 cm) apart to permit proper airflow. The acceptable ambient
temperature ranges are listed in Environmental Parameters.

Installing the S55 System 17
The fan speed increases when the internal temperature reaches 72 degrees C, and decreases to normal
speed when the temperature falls to 58 degrees C. The switch never intentionally turns off the fans.
Use the ltohii uiocommand to see the log messages. For details, see the System Logs chapters of the
FTOS Command Reference and FTOS Configuration Guide.
Power
Use the appropriate power cord with the S55 chassis to connect the chassis to the applicable (AC or DC)
power source. Power cords for US AC and DC are included with the system.
When installing AC systems, follow the requirements of the National Electrical Code, ANSI/NFPA 70
where applicable.
The system is powered-up as soon as the power cord is connected between the system and the power
source.
Storing components
If you do not install your system and components immediately, Force10 Networks recommends that you
properly store the S55 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.
Attention: Do not mix power supply types. The redundant power supplies must be the same type AC or
DC.
Caution: Always disconnect the power cable, before the power supply slots are serviced
Caution: The power supply cord is used as the main disconnect device on the AC and the DC system;
ensure that the socket-outlet is located/installed near the equipment and is easily accessible.
Attention: Electrostatic discharge (ESD) damage can occur when components are mishandled. Always
wear an ESD-preventive wrist or heel ground strap when handling the S55 and its accessories. After you
remove the original packaging, place the S55 and its components on an antistatic surface.

Chapter 3 Install the S55
Attention: Always wear an ESD-preventive wrist or heel ground strap when handling the S55 and its
components. As with all electrical devices of this type, take all the necessary safety precautions to prevent
injury when installing this system. Electrostatic discharge (ESD) damage can occur if components are
mishandled.
Note: Force10 recommends attaching the brackets at the PSU side. This provides the greatest weight
support for the chassis in the rack or cabinet.

20 Install the S55
Follow these steps to attach the brackets to the chassis:
Install chassis into rack or cabinet
Ensure that there is adequate clearance surrounding the rack or within the cabinet to permit access and
airflow. Follow the steps below to install a switch into a two-post 19-inch equipment rack, using the
already attached mounting brackets.
Step Task
1Take the brackets and screws out of their packaging.
2 Attach the brackets to the sides of the chassis at the PSU end, using four screws for each bracket.
Attach the bracket so that the “ear” faces to the PSU and the outside of the chassis.
Step Task
