Installing the Hardware 5
1
Installing the Hardware
This guide assumes all site preparation has been performed before installing the
chassis.
Installing the Chassis
To install the S50 chassis, Dell Force10 recommends that you complete the
installation procedures in the order presented below.
NOTE: Unless stated otherwise, the installation instructions below apply to both
the S50N and S50V chassis.
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 the 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 S50N and S50V 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 S50N and
S50V Systems guide.
This document does not include stacking or installing stacked units. Refer to the
Installing S50N and S50V Systems guide for details on stacking installation and
cabling.

6Installing the Hardware
Attach a Ground Cable to the S50N and S50V Chassis
The S50V and S50N switches have both AC (3-prong plug receptacle) and DC
(-48V terminal-type) connections on the back of the unit. They can use either
power source independently or in combination, with the DC source in a backup
mode (except for the 470W DC power supply). If you select AC and DC, the
switch will only use the DC source after the AC source fails.
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.
Attach a Ground Cable to the S50N-DC Chassis
The S50N-DC switches have two terminal blocks on the right side (instead of an
AC receptacle) for two DC power supply inputs. The terminal block on the
right, as you face the back of the chassis, is matched to the DC1 status LED on
the front left of the switch and the left block is matched to the DC2 status LED.
Step Task
1Dell Force10 recommends that one person hold the chassis in place
while a second person attaches the brackets to the posts.
2Attach the bracket "ears" to the rack or cabinet posts, using two screws
for each bracket. Ensure the screws are tightened firmly.

Installing the Hardware 7
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 -48VDC input (per NEC in the
United States; internationally, follow local safety codes.).
Connect 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.
Install the SFP and XFP Optics
The S50N and S50V each have four receptacles at the right end of their
faceplates that accommodate 10/100/1000 SFP optical transceivers.
A 10GbE module contains two ports. 10GbE modules should only be inserted or
removed when the switch is powered down. Refer to the Installing S50N and S50V
Systems guide for information related to optional module installation.
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.
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 or XFP so it is in the upright position. (The SFP optic
has a key that prevents it from being inserted incorrectly.).
2Insert the optic into the port until it gently snaps into place.

8Installing the Hardware
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
Power Up Sequence
Supply Power and Power Up the System
There is no power switch. Connecting the switch to either an AC or DC power
source starts the switch. The S50V and S50N switches have both AC (3-prong
plug receptacle) and DC (-48V terminal-type) connections on the back of the
unit. They can use either power source independently or in combination, with
the DC source in a backup mode (except for the 470W DC power supply). You
have three options for providing power to the switch — AC only, DC only, or
using both AC and DC sources. If you select the third choice — AC and DC —
the switch will only use the DC source after the AC source fails.
The rear of the S50N and S50V models have both an auto-sensing 110/220V AC
receptacle and a standard -48V terminal-type DC connector. The rear of an
S50N differs only in the arrangement of the lugs on its DC terminal block. Each
system ships only with the AC power cord.
Dell Force10 recommends re-inspecting your system prior to powering up.
Verify that:
• The equipment is properly secured to the rack and properly grounded.
• The equipment rack is properly mounted and grounded.
• The ambient temperature around the unit (which may be higher than the
room temperature) is within the limits specified for the unit.
• There is sufficient airflow around the unit.
• The input circuits are correctly sized for the loads and that sufficient over-
current protection devices are used.

Installing the Hardware 9
• All protective covers are in place.
• Blank panels are installed if optional modules are not installed.
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.
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.
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.
AC Power
For the S50V and S50N, 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
chassis) and then to the power source. Connect the plug to the AC receptacle,
making sure that the power cord is secure. As soon as the cable is connected
between the system and the power source, the chassis is powered-up; there is no
on/off switch.
DC Power
To connect the chassis to the DC power source, follow the steps below:
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 -48 V and -48 V RTN (Return) cables to the switch
terminals and then to the remote power sources, ideally on separate
circuit breakers.
4Replace the safety covers on the DC terminal blocks.
5If 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 S50N-DC does not set a precedence for either power
source.

10 Installing the Hardware
Power Supplies
On both the S50N and S50V, 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, with six fans on the left side of the switch as you face
the PSU side.
The fan speed increases when the temperature reaches 72 degrees C, and
decreases to normal speed when the temperature falls to 57 degrees C. The
switch never intentionally stops managing traffic.
Status logging is identified by unit in the system log.
Fan replacement in the field is not offered as an option.

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 I/O side of the chassis.

Accessing the Console Port
Connect the RJ-45/DB-9 adapter that is shipped with the S50V system to the RJ-
45 cable.
Step Task
1Install the RJ-45 copper cable that is shipped with the S50V 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 S50V
system to the end of the RJ-45 cable that will connect to your terminal.
3Set your initial console terminal settings to match the default console settings on
the switch.

Default Configuration
A version of 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 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 the 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.

Access the System Remotely
You can configure the system to be accessed remotely by Telnet.
The S50N and S50V chassis do not have a dedicated management port.
Configure any port on the chassis to be the port through which you manage the
system and configure an IP route to that gateway.

Installing the Software 17
Configure the Enable Password
The EXEC Privilege mode is accessed by the enable command. Configure a
password as a basic security measure. When using a console connection, EXEC
Privilege mode is unrestricted by default; it cannot be reached by a VTY
connection if no password is configured. There are two types of enable
passwords:
• enable password stores the password in the running/startup configuration
using a DES encryption method.
• enable secret is stored in the running/startup configuration in using a
stronger, MD5 encryption method.
Dell Force10 recommends using the enable secret password.
Create a VLAN
The Default VLAN is part of the system startup configuration, and is by default,
VLAN 1. You may make another VLAN the Default VLAN. The Default
VLAN cannot be deleted, disabled, or configured (you cannot assign it an IP
address), and only untagged interfaces can belong to it.
When an interface is configured, a switchport automatically places it in the
default VLAN as an untagged interface. All switchports must belong to at least
one VLAN, so to remove a switchport from the Default VLAN, you must place
it as tagged or untagged in some other VLAN, or remove the switchport
configuration.

18 Installing the Software
Assign Interfaces to a VLAN
A port may either be an untagged member of a single VLAN, or a tagged
member of perhaps multiple VLANs.
• Untagged Ports — ports that do not append an 802.1Q VLAN tag to frames
on egress, and do not accept tagged frames on ingress (tagged frames are
dropped). Untagged ports must be connected to VLAN-unaware devices.
• Tagged Ports — ports that append an 802.1Q tag to frames on egress, and
accept only tagged frames on ingress (untagged frames are dropped). Tagged
ports must be connected to VLAN-aware devices.
When you configure an enabled port as a switchport, the port is placed in the
default VLAN. To remove a switchport from the default VLAN, remove the
switchport configuration. To move the port to another VLAN, add it to the
desired VLAN as either a tagged or untagged member.
To view just the interfaces that are in Layer 2 mode, enter the show interfaces
switchport command in the EXEC mode.
Assign an IP address to a VLAN
NOTE: An IP address cannot be assigned to the Default VLAN, which, by default,
is VLAN 1. To assign another VLAN ID to the Default VLAN, use the default
vlan-id vlan-id command.
