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

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.

, 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.

Backup Power Components on page 29

See

.

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

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

), you can

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

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.

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

Step Task

1 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.

2 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

n00144s50V

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.

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:

Installing the System on a Tabletop

http://www.force10networks.com/CSPortal20/KnowledgeBase/

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.

Installing the Switch | 23

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:

• Assign a new management unit:

• Remove a unit from stack membership:

www.dell.com | support.dell.com

You can also use commands such as switch priority and member that override the default unit

switch renumber

movemanagement

no member

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

• Use the

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.

24 | 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.

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
use, see

Connecting S50V Ethernet Ports with PoE on page 42

Chapter , Installing Backup Power, on page 29

.

. For PoE

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

Requirements on page 48

). Connect the plug to the AC receptacle at the right rear of the switch, making

AC Power

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

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.

1 Make sure that the remote power source (the circuit breaker panel) is in the OFF position.
2 Remove the safety cover from the DC terminal block.
3 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.

4 Connect the -48 V and -48 V RTN (Return) cables to the switch terminals and then to the remote

www.dell.com | support.dell.com

power sources, ideally on separate circuit breakers.

5 Replace the safety covers on the DC terminal blocks.
6 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

• 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

Warnings on page 5

.

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

).

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

• PSU mounting hardware: captive screws for attaching the unit to the External Power Shelf (EPS)

34 | Installing Backup Power

• 5’(1.5m) DC-to-DC cable (two versions are included with the rectifier; see below.)

• AC cable to the 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

Figure 5-10. Front and Back Views of External Power Shelf (EPS)

. It is a 2.5RU chassis that can house up to eight PSUs (for up to eight switches).

(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:

1 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.

2 Slide the PSU into the bay until its front panel is flush with the shelf.
3 Secure it by tightening the screws on the left and right sides of the PSU.

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

NOTE: You can also attach PSUs to one or both of the terminal blocks of an S50N-DC. The connections are

Pin 5 = GND
Pin 6 = TXD

• No flow control (console port only)

After establishing a connection, you can
modify the settings to match at each end
of the connection.

Pin 7 = NC
Pin 8 = NC

To access the console port, follow the procedure below.

Step Task

1 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

Step Task (continued)

4 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

www.dell.com | support.dell.com

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. RJ-45 PoE Pinout

Figure 6-2

.

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

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.

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

page 17

Inserting Optional Modules (10-Gigabit or Stacking) on

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:
