System Overview
The S50V and S50N models of the Dell Force10 S-Series are stackable, Layer 2 switch/Layer 3 routers
with 48 built-in 10/100/1000 Base-T ports, four SFP ports, and up to four optional 10-Gigabit (10GbE)
ports (XFP or CX4), in two expansion slots. Figure 2-1 shows the front panel of the S50V. The S50N has
the same layout; just the catalog number differs. The S50N-DC (see Figure 3-1 on page 15) differs only in
that DC1 and DC2 status LEDs appear where the AC and DC status LEDs are on the S50V and S50N.

menu options, both discussed here, along with CLI show commands, and SNMP traps. For details on
those options, see the Command Reference and Configuration Guide for your software (FTOS or
SFTOS).
LED Displays
As shown in Figure 2-2 on page 9, the front panel of the switch contains several sets of LEDs:
• Stack ID: This is the LED at the far left of the front panel labeled “STACK ID”. See Stack ID in
Table 2-2 on page 12). For more on stack unit numbering, see Stacking on page 23.
• Status indicator LEDs on the left side of the front panel, to the right of the Stacking LED. See Table 2-2.

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
Ventilation is side-to-side, with six fans on the left side of the switch. For proper ventilation, position the
switch 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 S-Series systems are installed side by side, 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 on page 48.
As listed in Table 2-2 on page 12, the front panels of the S50N and S50V series have an Alarm status
LED, which is green when the switch is operating within required temperature parameters and all
components are operating normally, including fans. The LED is amber when the temperature or
components are outside expected parameters, red in a major alarm.
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.
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. The Command Line Interface (CLI) also
reports an alarm.
Use the show logging command to see the log messages. For details, see the System Logs chapters of the
SFTOS Command Reference and 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 in the field is not offered as an option.
Power
S50N-DC
As shown below, the right side of the S50N-DC contains two terminal blocks for two 150W DC power
supply inputs. The terminal blocks are labeled DC1 and DC2, which corresponds to the labels of the
status LEDs on the front left of the switch. When both blocks are connected, they act in load-sharing
mode with backup capability (one power supply can run the whole system).

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.
As shown in Figure 2-2 on page 9, 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 (Figure 3-1). Each system ships only with the AC
power cord. There is no power switch. Connecting the switch to either an AC or DC power source starts
the switch.
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.
On the S50V, when the Dell Force10 470W DC Backup Power Supply is connected to the Current
Sharing connection on the S50V DC terminal block, the switch uses the DC and AC power supplies in
current-sharing (load-sharing plus additive) mode, so that the total capability is 470W+470W = 940W.
See Backup Power Components on page 29.
Dell Force10 also offers an external 180W DC power supply for the S50N and S50N-DC models, the
same power supply used by the S50. However, the connections differ from those on the S50, so the power
supply ships with DC cables to support each model. Rack-mounting hardware is supplied. For details on
connecting to a power source, see Supplying Power on page 27.
Power over Ethernet (PoE) Support
Along with the optional DC power supply noted above, the S50V includes an internal 470W power
supply that supports both the operation of the switch and an independent power distribution system to
supply power to the 48 copper Ethernet ports, supporting the IEEE 802.3af standard for Power over
Ethernet (PoE). Connect only powered devices that adhere to IEEE 802.3af.
Site Preparations
|
15
www.dell.com | support.dell.com
The total PoE power budget for the switch is between 320W and 790W, depending on the power sources
available. If the external 470W Redundant Power Supply (catalog # S50-01-PSU-V) from Dell Force10
is attached to the Current Sharing terminal (see Chapter , Installing Backup Power, on page 29), you can
use the power-budget command in FTOS to convert the power supply to current-sharing mode to
provide up to 790W of PoE. When running SFTOS, use the inlinepower threshold command.
Each port can provide a maximum of 15.4W, subject to the power budget, voltage, power priority, and
power limit settings. PoE is, by default, enabled globally on a first-come, first-serve basis, until it exceeds
the total available power. Alternatively, the switch administrator can use the CLI to allocate power on a
per-port and a per-stack-unit basis, with per-port power limits and port prioritization. For a brief
introduction in this guide to the PoE commands, see Connecting S50V Ethernet Ports with PoE on page 42.
For details, see the PoE Commands sections in the Command Reference and Configuration Guide for
your software.
Storing Components
If you do not install your system and components immediately, Dell Force10 recommends that you
properly store the switch and all optional components until you are ready to install them.
WARNING: Electrostatic discharge (ESD) damage can occur when components are mishandled. Always
wear an ESD-preventive wrist or heel ground strap when handling the switch and its accessories. After you
remove the original packaging, place the switch and its components on an antistatic surface.
Follow these storage guidelines:
• Storage temperature should remain constant, in the range from -40° to 158° F (-40°C to 70° C).
• Storage humidity should be within 10 to 90% (relative humidity), non-condensing
• Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
• Store in a dust-free environment.
Tools Required
S-Series switches are shipped fully assembled, encased in foam. A utility knife is useful for cutting the
packing tape, and a Phillips #2 screwdriver is required for attaching rack screws, and is also used for
making some attachments, including DC cables and rear cover plates. Wear an anti-static guard, as noted
above.

Installing the Switch
To install S50V or S50N systems, Dell Force10 recommends that you complete the installation
procedures in the order presented in this chapter:
• Inserting Optional Modules (10-Gigabit or Stacking)
• Installing the System on a Tabletop on page 18
• Installing the System in a Rack or Cabinet on page 19
• Stacking on page 23
• Supplying Power on page 27
WARNING: 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. Always wear an
ESD-preventive wrist or heel ground strap when handling the switch and its components. See other relevant cautions in
the Preface.
Inserting Optional Modules (10-Gigabit or Stacking)
The S50V (catalog number S50-01-GE-48T-V) and S50N (catalog number S50-01-GE-48T-AC for ACpowered version of S50N; S50-01-GE-48T-DC for S50N-DC) have two expansion slots in the back of
the chassis, for which there are four modules available:
Module Description
Catalog Number
2-port 10GbE XFP (optical connection)
S50-01-10GE-2P
2-port 10GbE CX4 (copper connection)
S50-01-10GE-2C
2-port 12GbE Stacking
S50-01-12G-2S
1-port 24GbE Stacking
S50-01-24G-1S
The system supports any of the modules inserted in any combination of slots (although connecting all
four ports of two 12G stacking modules is not supported, nor is connecting a 12G stack port in one switch
to a 24G stack port in another switch). The ports are numbered 49 through 52, from left to right as you
face the front of the chassis. So, for clarity in the use of the CLI in port assignment, if you are only using
one XFP or CX4 module, insert it in the left-most expansion slot.
NOTE: The
10G modules cannot be used for stacking. See Connecting Stack Ports (optional) on
page 25.

To install a module, follow the steps below:
Step
1
Task
If the system is on, save the running configuration, if desired (and different from the startup configuration) with
the command write memory. Then power down the system by unplugging it from its power source.
CAUTION: Hot-swapping (inserting or removing) a module can crash and lock up the system, requiring a
power cycle.
Use a #2 Phillips screwdriver to remove either a module faceplate or an existing module. Note that these slots,
when used for 10G Ethernet ports, are assigned port numbers from left to right as you face the front of the system.
So, for clarity in programming those ports, you might favor the left-most slot for the first 10G module that you
install.
3
Grasp the module faceplate, and remove the module from its packaging, then slide it into the slot until the module
faceplate is flush with the rear cover of the system.
4
Secure the captive screws on either side of the module.
5
The optical XFP 10-Gigabit module (Catalog # S50-01-10GE-2P) requires additional XFP transceiver inserts,
which are not included in the module kit. See Installing XFPs on page 44 or the installation instructions that come
with the transceiver.
fn00144s50V
2
CAUTION: You can connect a CX4 cable to an XFP port through a CX4 XFP converter (catalog number
GP- XFP-1CX4) in the slot. However, an XFP port does not support the use of the cx4-cable-length command,
discussed next.
CX4 module (catalog number S50-01-10GE-2C) ports do not require inserts. If you are installing a CX4 module,
and you are connecting the ports with a cable substantially shorter or longer than 5 meters, use the cx4-cablelength command to set the signal strength. Use cx4-cable-length long for a longer cable, cx4-cable-length short
for a shorter cable. For details when using FTOS, see the Interfaces chapter in the FTOS Command Reference.
When using SFTOS, see the System Management Commands chapter in the SFTOS Command Reference for
details.
NOTE: Take care not to connect CX4 ports to 12G stack ports in the switch. The receptacles and cables are
the same, but they are incompatible. CX4 ports are labeled as such; stack ports are not labeled. You can order
several cable lengths of each type; they are not part of the module kit. For details, see Using CX4 Cables (CX4
Cable Matrix) in the S-Series tech tips on iSupport: http://www.force10networks.com/CSPortal20/KnowledgeBase/
ToolTipsSSeries.aspx
Installing the System on a Tabletop
The system can be positioned on a stable tabletop. Four rubber standoffs are provided for that purpose in
the plastic bag in the switch shipping box. Keep the following in mind when using a tabletop:
18
|
Installing the Switch
• Ensure that your tabletop is stable and can handle the weight of the switch or a stack of switches, if that
is the case, along with any added backup power supplies.
• Position the table for proper ventilation and easy access to separate power outlets for each device.
Installing the System in a Rack or Cabinet
The system provides three rack-mounting methods:
• Two-Post Rack Mounting
• Four-Post Rack-mounting with Threaded Rails
• Four-Post Rack-mounting with Cage Nuts
Two-Post Rack Mounting
The switch 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. If you are installing two switches
side-by-side, position the two chassis at least 5 inches (12.7 cm) apart to permit proper airflow.
Position the chassis in the rack. Secure the chassis with two of the supplied screws through each bracket
and onto the rack post.

Stacking
You can add, remove, or swap units in an existing stack. The units in the stack can continue running as
you add new units, but new units should be powered down during the connection.
All units in a stack must run the same version of the operating system. If you attempt to attach a unit with
a different version of the operating system to an existing stack, the CLI will display an error, and the unit
will not be added until you install compatible software.
The order in which the units come on-line or are added to or removed from the stack can affect how the
stack identifies them, and how the units identify themselves, influencing unit numbers, management
addresses, and other elements of the configuration file.
How units are identified within the stack is determined by the selected identification algorithm. The
default algorithm has the units self-identify as Unit 1 through Unit [last] based on the order in which they
come on-line. So, when setting up a new stack, you should have no trouble forcing the identification of
the management unit and unit IDs by methodically supplying power to the units in your preferred
sequence.
Similarly, when you add a brand new unit to the stack, the unit will be gracefully added as Unit [last] (the
lowest unused number) with the current configuration.
If you have a pre-configured unit to add to the stack, but you want to make sure that the configuration
does not override the configuration of the stack, it is best to add the unit while it is powered down, in
order to avoid stack management conflicts.

Using SFTOS Stacking Commands
If the switch is running SFTOS, the commands available to manage stacking are described in the
Stacking chapters of the SFTOS Command Reference and the SFTOS Configuration Guide.
You can execute clear config on the switch to start a clean configuration. Then pre-configure it, as
recommended in Best Practices in the Stacking chapter of the SFTOS Configuration Guide.
You can use the SFTOS CLI to make stack identification changes on the fly:
• Renumber units: switch renumber
• Assign a new management unit: movemanagement
• Remove a unit from stack membership: no member
You can also use commands such as switch priority and member that override the default unit
identification algorithms.
Use the show switch command to see the current assignment of the management unit.
Use the show switch unit command to see the serial number of the designated unit.
For details on and other stacking commands, see the Stacking chapter in the SFTOS Configuration Guide
and the Stacking Commands chapter in the SFTOS Command Reference.
Using FTOS Stacking Commands
If the switch is running FTOS, the following commands are available to manage stacking:
• Use the stack-unit unit priority 1-14 command to configure the ability of an S-Series switch to become
the management unit of a stack.
• Use the stack-unit unit provision {S25N|S25P|S25V|S50N|S50V} command to pre-configure a
stacking ID of a switch that will join the stack. This is an optional command that is executed on the
management unit.
• Use the stack-unit unit renumber unit command to renumber a standalone S-Series or any stack
member except the management unit.
• Use the show system brief command to see the current assignment of the management unit.
• Use the show system stack-unit unit command to see the serial number of the designated unit and
other system details.
• Use the show system stack-ports command to see the stacking topology and status.
For details on using FTOS to remove a unit from a stack or use other stacking commands, see the
Stacking Commands chapter in the FTOS Command Reference and the S-Series Stacking chapter in the
FTOS Configuration Guide.

Installing the Switch
Connecting Stack Ports (optional)
The switch contains two expansion slots in the rear, in either of which you can insert stacking modules
for converting the switch into a virtual slot in a single virtual switch, called a stack, comprised of any SSeries model running the same software. The S50V and S50N include two optional choices in stacking
modules — a single-port 24G module and a two-port 12G module. You cannot interconnect the two
types. If you use single-port 24G modules, you can insert one in each expansion slot to accomplish the
ring topology.
You can connect the switches while they are powered down or up. You can use either a ring topology or
cascade topology connection (see Figure 4-3). Use the special stacking cables to connect them. Dell
Force10 recommends that you mount the switches before you make your stack port connections.

ring topologies.
Figure 4-4 shows the use of 24G stacking ports in each of the two rear modules to create a ring. Of course,
this topology does not allow the use of any rear modules for XFP ports. A cascade topology, removing
the stack port modules in the B slots of switches 1 and 2, would free those slots for use by XFP modules.

Connecting Three Switches
Dell Force10 recommends the ring topology, as outlined above (Figure 4-3 on page 25), for stacking SSeries switches, providing redundant connectivity. Using the example of three switches in the stack
(Figure 4-6), and starting with the switch at the bottom of the stack:
• Insert one end of the first cable into Stack Port A.
• Insert the other end of the cable into Stack Port A of the middle switch.
• Insert the second cable into Stack Port B of the middle and top switches.

Installing the Switch
• Connect the remaining cable to the top and bottom switches by inserting one end of the cable into the
open Stack Port B of the bottom switch and the other end of the cable into Stack Port A of the top
switch.

Supplying Power
Supply power to the switches in a stack only after they are mounted and the stack ports are connected.
There is no on/off switch, and the stack members partly determined the stack management unit from the
order in which they come on-line (see below).
The S50V and S50N switches have both AC (3-prong plug receptacle) and DC (-48V terminal-type)
connections on the back of the unit (see Figure 2-2 on page 9 and Figure 3-1 on page 15). 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, as noted in the section Power on page 14). In other words, 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.
In addition, Dell Force10 provides, as an option, an external DC Redundant Power Supply Unit (PSU),
which has an AC input and a cable for connecting the PSU to the DC terminal leads on the switch. To
connect the switch to a DC power supply, refer to Chapter , Installing Backup Power, on page 29. For PoE
use, see Connecting S50V Ethernet Ports with PoE on page 42.
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 rear of the chassis) and then to the power source (see AC Power
Requirements on page 48). Connect the plug to the AC receptacle at the right rear of the switch, making
sure that the power cord is secure.
S50N-DC
As shown in the section Power on page 14 in the Site Preparation chapter, 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
Installing the Switch
|
27
www.dell.com | support.dell.com
front left of the switch (see Figure 2-2 on page 9); the left block is matched to the DC2 status LED.
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.). Before you make the cable connections, apply a coat of antioxidant paste to unplated metal
contact surfaces. File unplated connectors, braided straps, and bus bars to a shiny finish.

|
Make sure that the remote power source (the circuit breaker panel) is in the OFF position.
Remove the safety cover from the DC terminal block.
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.
Connect 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.
Replace the safety covers on the DC terminal blocks.
If 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.

Installing Backup Power
This chapter covers the following topics:
• Backup Power Components
• The Power Connections on the Switch on page 30
• Installing the Backup DC Power Supply for the S50V on page 30
• Inserting Tandem S50V PSUs into a Rack on page 31
• Connecting the S50V DC-to-DC Cable on page 32
• Installing the Backup DC Power Supply for the S50N on page 34
• DC Components on page 34
• Installing the External Power Shelf (optional) on page 35
• Inserting an S50N PSU into the EPS on page 36
The S50V and S50N switches have both AC and DC power connections (S50N-DC has two DC terminal
blocks, no AC). You can connect either one or both. When both are connected, the AC input is slightly
preferred over the DC (about 60% / 40%). When you connect the Dell Force10 470W DC Power Supply
Unit (PSU) to the Current Sharing terminal of the S50V, the AC and DC are in additive mode, totalling
940W.
NOTE: Neither internal nor external S-Series power supplies are field serviceable. If an internal power supply
fails, the switch must be replaced.
WARNING: 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. See other relevant cautions in Information Symbols and
Warnings on page 5.
Backup Power Components
The optional Redundant Power Supply Unit (PSU) for the S50V supplies 470W DC, supporting both the
switch itself and the PoE feature. The PSU kit includes:
• The AC/DC rectifier (catalog number S50-01-PSU-V)
• DC-to-DC cable to connect the PSU to the switch
• AC cable to connect the PSU to the AC power source
• PSU mounting hardware: extended rack ears, twinning plate, screws, cage nuts, and four rubber feet that
you can attach to the PSU if you want to set it on a table

The Power Connections on the Switch
The S50V and S50N contain both AC and DC connections. An AC cable is supplied with the switch (see
Supplying Power on page 27). You can connect one or both of the AC or DC inputs to power. If both
connections are made and able to supply power, the switch will use them in load-sharing mode.
The DC input to the switch uses industry-standard terminal leads on a terminal block. The S50V has four
connections — ground (FG), -48 volt input, return (RTN), and Current Sharing, as shown in Figure 5-1:
Figure 5-1.
DC Terminals on the S50V
The S50N has three DC connections — return (RTN), -48 volt input, field ground (FG) — from left to
right.
Figure 5-2.
DC Terminals on the S50N
The S50N-DC has two terminal blocks, each with the same three DC connections as the S50N.
WARNING: A qualified electrician should make the DC connections.
Installing the Backup DC Power Supply for the S50V
The Redundant Power Supply Unit (PSU) for the S50V is a 470W AC/DC rectifier. It includes rackmounting hardware, an AC cable, and a cable to connect to the DC power leads on the S50V. The power
supply is oversized to support the Power over Internet (PoE) feature, too large to install in the S50
External Power Shelf. Instead, to install the Redundant Power Supply in a rack, complete the steps below

Connecting the S50V DC-to-DC Cable
The PSU kit for the S50V includes two power cables — the cable that connects the PSU to the AC source
and the DC-DC cable that connects the PSU to the terminal block on the back of the S50V. The DC-DC
cable length is 1.5 meter (5 feet), with a keyed plug connector at one end that connects to the PSU, and, at
the other end, individual wires that connect to the DC terminal leads in the rear of the S50V (Figure 5-7).

DC-DC Cable for S50V PSU
Follow the steps below to connect the S50V switch to the S50V external PSU.
Step
1
Task
With the switch unplugged from AC power, connect the individual leads of the DC-to-DC cable to the DC
terminal lugs of the switch (Figure 5-8), with a #2 Phillips screwdriver.
Connect the gray wire to FG, red to RTN, brown to -48V. If you connect the blue lead of the Dell Force10 PSU to
Current Sharing, you put the PSU in load-sharing mode, which helps to enable more PoE ports. Alternatively,
leaving the wire unconnected puts the PSU in backup mode. The downside of selecting load-sharing mode is that,
if either the AC or DC fails, all PoE functionality is lost.
Figure 5-8.
DC Terminals of the S50V Connected to the PSU Cable
CAUTION: Use only -48V DC. Using a higher voltage causes the DC source to take precedence over the
internal AC PSU, causing the AC PSU to continually attempt to boot up. The symptom is a clicking noise.

Task
Insert the plastic plug of the DC-to-DC cable into the receptacle on the lower left side of the DC Power Module
(DPM), which is the bottom box in Figure 5-9.
Note that one of the three leads on the plug has a trapezoidal key
, which goes in the receptacle that is toward
the center of the PSU. The key is not strong enough to resist being inserted in the opposite receptacle, and it is
difficult to see, so you must take care to insert it correctly. To help you orient it, note that the top side of the plug
has a knurled pattern.

Insert the supplied AC-to-AC cable into the AC receptacle of the DC power supply. Ideally, you should connect
that cable to an AC source separate from the AC connection made directly to the S50V.
Installing the Backup DC Power Supply for the S50N
The Redundant Power Supply Unit (PSU) for the S50N is a 180W AC/DC rectifier. It is less powerful
than the S50V PSU, because it does not need to support PoE.
This 180W PSU is the same as used for the S50, so it can be housed in the External Power Shelf supplied
for the S50. It does not have screw holes for rack ears, so it cannot be hung in a rack by itself.
CAUTION: Use only the power cords supplied with the power supply. Do not supply power to the system until
the power supply and modules have been installed.
DC Components
• The External Power Shelf (EPS) (Catalog# SA-01-EPS)
• S50/S50N Power Supply Unit (PSU) (Catalog# SA-01-PSU), an external AC-to-DC rectifier

Installing the External Power Shelf (optional)
Installing the PSU in a rack requires the External Power Shelf (EPS) (Catalog# SA-01-EPS), shown in
Figure 5-10. It is a 2.5RU chassis that can house up to eight PSUs (for up to eight switches).
Figure 5-10.
Front and Back Views of External Power Shelf (EPS)
(before inserting PSUs)
Figure 5-11.
EPS Mounting Bracket
Shown here on its side, the bracket (rack ear) used for front and rear mounting of the EPS has two holes at one
end of the rack flange that are closer together than those at the other end.
When attached to the front corners of the EPS, the close-set holes are at the top on the left side of the EPS and at
the bottom on the right side of the EPS.
To connect to the typical rack, you insert screws through the outside holes on the left-side flange and through the
inside holes on the right-side flange.
Procedure:
Attach the rack ears to the front or rear corners of the EPS, depending on where you are mounting it.
2 For front-mounting the EPC, slide the EPS into the rack from the front until the rack ears are flush
with the rack posts. Then secure the EPS by tightening the supplied screws through its left and right
rack ears. Figure 5-12 on page 36 shows the EPS mounted below an S50.

Connecting the DC-to-DC Cable for the S50N PSU
The PSU kit for the S50 and S50N includes an AC cable and two DC-DC cables. One DC-DC cable is for
the PSU-S50 connection (it has a plastic plug for connecting to the S50). The other DC-DC cable, for
connecting the PSU to the S50N, has, at the S50N end, three individual wires with fork connectors that
connect to the DC terminal block in the rear of the S50N (see Figure 5-15).
In both cases (S50 and S50N), the DC-DC cable length is 1 meter (39 inches), with, at the end that
connects to the PSU, a plastic plug containing two rows of three plastic connectors (see Figure 5-14).
NOTE: You can also attach PSUs to one or both of the terminal blocks of an S50N-DC. The connections are
the same as to the S50N.

• No flow control (console port only)
After establishing a connection, you can
modify the settings to match at each end
of the connection.
To access the console port, follow the procedure below.
Step
1
Task
Install 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, daisy chain 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.
2
If 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.
3
Verify that your terminal default settings match the default settings, as listed above, on the console port:
Installing Ports
|
41
www.dell.com | support.dell.com
Step
4
Task (continued)
If you use the console port to download software to the switch, you should raise the console baud rate. If SFTOS
is installed, 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.
If FTOS is installed, to make other console port configuration changes, such as setting the console port timeout or
setting up access security, use the line console command in the CONFIGURATION mode.
Connecting S50V Ethernet Ports with PoE
The copper ports (1 through 48) in the S50V are enabled by default to deliver power to connected
powered devices that follow the IEEE 802.3af specification for Power over Ethernet (PoE). For
delivering PoE, use the same Cat. 5 cables and RJ-45 connectors that you use for non-PoE connections.
The PoE pinout is shown in Figure 6-2.
Figure 6-2.
RJ-45 PoE Pinout
The internal AC 470 watt power supply will limit PoE power to 320 watts if the switch requires power for
other uses, and the default PoE configuration limits PoE power to 288 watts. As described in Power over
Ethernet (PoE) Support on page 15, you can raise that limit with an external power supply running in loadsharing mode and with certain FTOS and SFTOS commands. The PoE commands of FTOS and SFTOS
are summarized here.
NOTE: For details on commands that control PoE, see the PoE chapters of the Configuration Guide and
Command Reference for your software.

Installing Optics
This section contains two subsections:
• Installing SFPs on page 43
• Installing XFPs on page 44
The S50N and S50V each have four receptacles at the right end of their faceplates that accommodate
10/100/1000 SFP optical transceivers.
On the back of the switches, there are two bays that accept either stacking modules or 10GbE modules
(CX4 or XFP). A 10GbE module contains two ports. 10GbE modules should only be inserted or removed
when the switch is powered down, as detailed in Inserting Optional Modules (10-Gigabit or Stacking) on
page 17 in Chapter 4, Installing the Switch.
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. Optical specifications for Dell Force10 branded
devices are at the following URL: http://www.force10networks.com/products/mediaspecifications.asp
Dell Force10 offers various types of SFP and XFP transceivers. For details, see:
http://www.force10networks.com/products/specifications.asp
Installing SFPs
To install an SFP transceiver into an open optical port at the right front of the switch, use the steps below:

the framework for the return and recycling of used batteries and accumulators as applicable throughout
the European Union. This label is applied to various batteries to indicate that the battery is not to be
thrown away, but rather reclaimed upon end of life per this Directive.
In accordance with the European Directive 2006/66/EC, batteries and accumulators are labeled to
indicate that they are to be collected separately and recycled at end of life. The label on the battery may
also include a chemical symbol for the metal concerned in the battery (Pb for lead, Hg for mercury and
Cd for cadmium). Users of batteries and accumulators must not dispose of batteries and accumulators as
unsorted municipal waste, but use the collection framework available to customers for the return,
recycling and treatment of batteries and accumulators.
Customer participation is important to minimize any potential effects of batteries and accumulators on the
environment and human health due to the potential presence of hazardous substances. For proper
collection and treatment, contact your local Dell Force10 representative.

The serial numbers of the optional data modules (10G Ethernet and Stacking) are located on labels on
their faces (some early-production modules have the PN on their baseboards). For serial numbers of the
SFP optics, you can also access them through the CLI with either the show hardware or show runningconfig commands.
The serial number label of the optional DC Backup Power Supply (see Backup Power Components on
page 29) is located on the base of the chassis.
Requesting a Hardware Replacement
To request replacement hardware, follow these steps:
Step
Task
1
Determine the part number and serial number of the component. To list the numbers for all components installed in
the chassis, use the show hardware command.
2
Request a Return Materials Authorization (RMA) number from TAC by opening a support case. Open a support case
by:
• Using the Create Service Request form on the iSupport page (see Contacting the Technical Assistance Center on
page 56).
