Installing the Hardware
This guide assumes all site preparation has been performed before installing the
chassis.
Installing the Chassis in a Rack or Cabinet
To install the S25N, S25V, or S25P system, Dell Force10 recommends that you
complete the installation procedures in the order presented below.
NOTE: Unless stated otherwise, the installation instructions below apply to the
S25N, S25V, and S25P systems.
Always handle the system and its components with care. Avoid dropping the
switch or its field replaceable units.
CAUTION: Always wear an ESD-preventive wrist or heel ground strap when
handling the chassis and its components. As with all electrical devices of this
type, take all necessary safety precautions to prevent injury when installing
this system. Electrostatic discharge (ESD) damage can occur if components
are mishandled.
Installing a Chassis in a Two-Post Rack
The chassis is shipped with the universal front-mounting brackets (rack ears)
attached. Ensure that there is adequate clearance surrounding the rack to permit
access and airflow.
The S25 chassis can be installed using several methods. This document
describes the most common installation method: two-post rack. For information
regarding other installation methods, refer to the Installing S25N and S25V Systems
guide and the Installing the S25P System guide.
This document does not include stacking or installing stacked units. Refer to the
Installing S25N and S25V Systems guide and the Installing the S25P System guide
for details on stacking installation and cabling.

6Installing the Hardware
Step Task

Installing the Hardware 7
Attach a Ground Cable to the System
CAUTION: To prevent electrical shock, make sure the switch is grounded
properly. If you do not ground your equipment correctly, excessive emissions
can result. Use a qualified electrician to ensure that the power cables meet
your local electrical requirements.
NOTE: The rack installation ears are not suitable for grounding.
CAUTION: Grounding conductors must be made of copper. Do not use
aluminum conductors.
NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping.
Bring any un-plated mating surfaces to a shiny finish, and coat with an anti-oxidant
prior to mating. Plated mating surfaces must be clean and free from contamination.
Connect the grounding cable to the FG terminal first (located on the PSU side of
the chassis), then connect the opposite end to the appropriate grounding point at
your site to ensure an adequate unit ground.
Install the SFP and XFP Optics
The S25 chassis have four receptacles on the I/O side that accommodate
10/100/1000 SFP optical transceivers. Additionally, the S25 has bays on the
PSU side that accommodate optional CX4 or XFP modules.
A 10GbE module contains two ports. 10GbE modules should only be inserted or
removed when the switch is powered down.
SFP and XFP transceivers can be inserted or removed while the switch is
running.
CAUTION: Before connecting a transceiver to a source, check the receive
power of the transceiver with an optical power meter. Generally, Dell Force10
specified optics are not to be subjected to receive power higher than that
stipulated by the optic specification. If the optic is exposed to optical power in
excess of the specification, there is a high likelihood that it will be damaged.
Installing SFPs
NOTE: When a copper SFP2 module with catalog number GP-SFP2-1T is used in
the S25P switch, the SFP speed can be manually set with the speed command.
When the speed is set to 10 or 100 Mbps, the duplex command can also be
executed.

8Installing the Hardware
CAUTION: Electrostatic discharge (ESD) damage can occur if components
are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the chassis and its components.
WARNING: Follow all warning labels when working with optical fibers.
Always wear eye protection when working with optical fibers. Never look
directly into the end of a terminated or unterminated fiber or connector as it
may cause eye damage.
Step Task
1Position the SFP so it is in the upright position. (The SFP optic has a key
that prevents it from being inserted incorrectly.).
2Insert the SFP into the port until it gently snaps into place.

Installing XFPs
CAUTION: Electrostatic discharge (ESD) damage can occur if components
are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the chassis and its components.
WARNING: Follow all warning labels when working with optical fibers.
Always wear eye protection when working with optical fibers. Never look
directly into the end of a terminated or unterminated fiber or connector as it
may cause eye damage.
CAUTION: You can insert and connect XFP transceivers while the switch is
operating. You can also disconnect and remove XFP transceivers while the
switch is operating. However, inserting or removing the module is not
supported; it can crash or lock up the switch, requiring a reboot.
CAUTION: The CX4 module does not use transceivers. However, you can use
a CX4 cable with an XFP port by inserting a CX4 XFP converter (catalog
name GP- XFP-1CX4) into the slot. An XFP port does not support the use of
the cx4-cable-length command.
NOTE: For details on Dell Force10 supported optics, refer to
http://www.force10networks.com/products/specifications.asp
Step Task
1Position the XFP so it is in the upright position. (The XFP optic has a
key that prevents it from being inserted incorrectly.).
2Insert the optic into the port until it gently snaps into place.

10 Installing the Hardware
Power Up Sequence
Supply Power and Power Up the System
There is no power switch. Supply power to the unit only after it is mounted.
CAUTION: To prevent electrical shock, make sure the switch is grounded
properly. If you do not ground your equipment correctly, excessive emissions
can result. Use a qualified electrician to ensure that the power cables meet
your local electrical requirements.
NOTE: A US AC power cable is included in the shipping container for powering
up an AC power supply. All other power cables must be ordered separately.
S25N
The S25N has two AC receptacles in the PSU side of the unit. The system can
use either power source independently, or act in load-sharing mode.
S25V
The S25V has both an AC (3-prong plug receptacle) and a DC (-48V terminal-
type) connection on the PSU side of the unit. Each power source can be used
independently or in load-sharing combination. In other words, you have three
options for providing power to the switch — AC only, DC only, or using both
AC and DC sources.
• To use AC only, connect the supplied AC power cord first to the switch
(receptacle on the right as you face the PSU side of the unit) and then to the
power source. Connect the plug to the AC receptacle, making sure that the
power cord is secure.
• For DC power, you must provide your own cables to connect to the power
source. Cables must be sized for 11.5 A service at no more than -48 VDC
input.
Step Task
1Make sure that the remote power source (the circuit breaker panel) is in
the OFF position.
2Remove the safety cover from the DC terminal block.

Installing the Hardware 11
S25P
The S25P has two AC power supplies acting in load-sharing mode or can be
used independently. Use the power cords shipped with the S25P to connect it to
AC power outlets, ideally on separate circuits. Several versions of the power
cord are available, based on country requirements.
S25P-DC
The PSU side of the S25P-DC contains two terminal blocks for two DC power
supply inputs acting in load-sharing mode. The left terminal block, as you face
the PSU side, corresponds to the DC2 status LED on the I/O side of the switch;
DC1 is on the right. Cables must be sized for 11.5 A service at -48VDC input
(per NEC in the United States. Internationally, follow local safety codes.)
3Connect the -48 V and -48 V RTN (Return) cables to the switch
terminals and then to the remote power sources.
4Replace the safety covers on the DC terminal block.
Step Task
1Make sure that the remote power source (the circuit breaker panel) is in
the OFF position.
2Remove the safety cover from the DC terminal block.
3Connect the grounding cable to the FG terminal first, then connect the
opposite end to the appropriate grounding point at your site to ensure an
adequate chassis ground.
4Connect the -48 V and -48 V RTN (Return) cables to the switch
terminals and then to the remote power sources, ideally on separate
circuit breakers.
5Replace the safety covers on the DC terminal blocks.
6If you are connecting both terminal blocks, do not supply power until
both terminal blocks are connected. You can supply power to either one
or both. The S25P-DC uses the power supplies in load-sharing mode
and does not set a precedence for either power source. Failover is
hitless.
Step Task

12 Installing the Hardware
CAUTION: Electrostatic discharge (ESD) damage can occur if components
are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the system and its components.
Power Supplies
On the S25N, S25V, and S25P systems, either the AC or DC power supplies
alone are sufficient to power the switch. When both AC and DC power supplies
are connected, they act in roughly a 60%/40% load-sharing mode.
WARNING: To prevent electrical shock, make sure the system 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.
Fans
Ventilation is side-to-side, on the switch as you face the I/O side. The fans
operate at a constant speed and with automatic speed adjustment for temperature
changes.
For the S25N and S25V, FTOS turns on major and minor alarms and logs
temperature warnings at the following temperatures (in degrees Celsius), and
logs another message when the temperature returns to normal. The Command
Line Interface (CLI) also reports an alarm. The fan speed changes accordingly.

Installing the Software
Navigating CLI Modes
The FTOS prompt changes to indicate the CLI mode. You must move linearly
through the command modes, with the exception of the end command which
takes you directly to EXEC Privilege mode; the exit command moves you up
one command mode level.
Console Access
Access the command line through a serial console port or a Telnet session.
When the system successfully boots, you enter the command line in the EXEC
mode.
NOTE: You must have a password configured on a virtual terminal line before you
can Telnet into the system. Therefore, you must use a console connection when
connecting to the system for the first time.
Serial Console
The RS-232 console port is labeled on the chassis. It is in the upper right-hand
side, as you face the PSU side of the chassis.

16 Installing the Software
Step Task
1Install the RJ-45 copper cable that is shipped with the system into the console
port.
CAUTION: You must install a straight-through RJ-45 copper cable
(a standard Ethernet cable) into the console port. This is different from
many other implementations that require an Ethernet crossover cable (or
rollover cable). If connecting to a terminal server and using a crossover
cable, daisychain another crossover cable to effectively get a straight-
through cable connection. Many console terminal servers use octopus
cables that are crossover cables. To accommodate the octopus cable,
connect an additional crossover cable, as above, to effectively install a
straight-through cable.
2If necessary, connect the RJ-45/DB-9 adapter that is shipped with the system to
the end of the RJ-45 cable that will connect to your terminal.

4S25P only: If you use the console port to download software to the switch, you
will probably want to raise the console baud rate. Establish a connection with
the default settings to verify the connection. Then use the lineconfig command
to access the Line Config mode, and use the serial baudrate command to raise
the baud rate on the console port. (Match the settings in your terminal access
program.)

Default Configuration
A version of the Dell Force10 Operating System (FTOS) is pre-loaded onto the
chassis, however the system is not configured when you power up for the first
time (except for the default hostname, which is Force10). You must configure
the system using the Command Line Interface (CLI).
Configure Layer 2 (Data Link) Mode
Use the switchport command in INTERFACE mode to enable Layer 2 data
transmissions through an individual interface. The user cannot configure
switching or Layer 2 protocols such as spanning tree protocol on an interface
unless the interface has been set to Layer 2 mode.
To view the interfaces in Layer 2 mode, use the show interfaces switchport
command in the EXEC mode.
Configure a Host Name
The host name appears in the prompt. The default host name is Force10.
• Host names must start with a letter and end with a letter or digit.
• Characters within the string can be letters, digits, and hyphens.
Access the System Remotely
You can configure the system to be accessed remotely by Telnet.
