Power Supplies
PS0
PS1
The S4820T supports two hot-swappable power supplies units (PSUs) and fans
that provide cooling for the system. The S4820T supports AC and DC power
supplies with two air-flow directions (I/O to PSU and PSU to I/O). Two PSUs
are required for full redundancy, but the system will operate with a single PSU.
NOTE: If you use a single PSU, you must install a blank plate in the other PSU
slot. Dell Force10 recommends using power supply 1 (PSU1) as the blank plate
slot.
The PSUs are field replaceable. When running with full redundancy (two power
supplies installed and running), you can remove and replace one PSU while the
other PSU is running without disrupting traffic.
The S4820T does not support mixing PSU types. You cannot replace an AC
PSU with a DC PSU and you cannot replace an AC-R PSU with a DC-R PSU.
WARNING: Electrostatic discharge (ESD) damage can occur if components
are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the S4820T and its components.
CAUTION: To prevent electrical shock, ensure the S4820T is grounded
properly. If you do not ground your equipment correctl y, excessive emissions
may result. Use a qualified electrician to ensure the power cables meet your
local electrical requirements.
Figure 1-4. S4820T Power Supply
12 Installation
Install an AC or DC Power Supply
To install an AC or DC power supply, follow these steps:
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as
this may damage the PSU or the S4820T chassis.
NOTE: Ensure that the PSU is correctly installed. When the PSU is correctly
installed, the power connector is on the left side of the PSU and the status LED is at
the top of the PSU
NOTE: If you use a single PSU, you must install a blank plate in the other PSU
slot. Dell Force10 recommends using power supply 1 (PSU1) as the blank plate
slot.
Step Task
1 Remove the PSU slot cover from the S4820T (PSU side of switch), either of the
two PSU slots may be selected.
2 Remove the PSU from the electro-static bag.
3
• Insert the PSU into the switch PSU slot (PSU exposed PCB edge connector
should be inserted first).
• The PSU slot is keyed such that the PSU can only be fully inserted in one
orientation.
• When the PSU is installed correctly it should snap into place and be flush with
the back of the switch.
4 Plug in the appropriate cord (AC 3 prong or DC wiring) from the switch PSU to
the external power source (either AC wall outlet or DC rack bus bar).
5 If you have a redundant PSU (2nd PSU), repeat steps 1 through 5 above using
the 2nd PSU slot on the S4820T switch.
NOTE: The system powers up as soon as the cables are connected between the
power supply and the power source.
Installation 13
Rack Mounting the Switch
You may either place the switch on the rack shelf or mount the switch directly
into a 19" wide, EIA-310-E- compliant rack (four-post, two-post, or threaded
methods). The Dell ReadyRails™ system is provided for 1U front-rack, and
two-post installations. The ReadyRails system includes two separately
packaged rail assemblies and two rails that are shipped attached to the sides
of the switch.
WARNING: This is a condensed reference. Read the safety instructions in your
Safety, Environmental, and Regulatory information booklet before you begin.
NOTE: The illustrations in this document are not intended to represent a specific
switch.
Rack Mounting Safety Considerations
•
Rack loading—Overloading or uneven loading of racks may result in shelf
or rack failure, causing damage to the equipment and possible personal
injury. Stabilize racks in a permanent location before loading begins.
Mount the components beginning at the bottom of the rack, then work to
the top. Do not exceed your rack load rating.
•
Power considerations—Connect only to the power source specified on the
unit. When multiple electrical components are installed in a rack, ensure
that the total component power ratings do not exceed the circuit
capabilities. Overloaded power sources and extension cords present fire
and shock hazards.
•
Elevated ambient temperature—If installed in a closed rack assembly, the
operating temperature of the rack environment may be greater than the
room ambient temperature. Use care not to exceed the 40
ambient temperature of the switch.
•
Reduced air flow—Install the equipment in the rack so that the amount of
airflow required for safe operation of the equipment is not compromised.
•
Reliable earthing—Maintain reliable earthing of rack-mounted
equipment. Pay particular attention to the supply connections other than
the direct connections to the branch circuit, for example: use of power
strips.
•
Do not mount the equipment with the rear panel facing in the downward
position.

26 Performing the Initial Configuration
Default Configuration
A version of FTOS is pre-loaded onto the S4820T system; however, the system is not
configured when you power up for the first time (except for the default host name, which
is FTOS). 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. You cannot configure switching
or Layer 2 protocols such as Spanning Tree Protocol (STP) on an interface
unless the interface has been set to Layer 2 mode.
To configure Layer 2 mode, follow these steps:
Step Task Command Syntax Command Mode
1 Enable the interface. no shutdown INTERFACE
2 Place the interface in
Layer 2 (switching)
mode.
To view the interfaces in Layer 2 mode, use the show interfaces switchport
command in EXEC mode.
switchport INTERFACE
Configure a Host Name
The host name appears in the prompt. The default host name is FTOS. Host
names must start with a letter, end with a letter or digit, and must have
characters, letters, digits, and hyphens in the string.
To configure a host name, follow this step:
Task Command Syntax Command Mode
Create a new host name. hostname name CONFIGURATION
Performing the Initial Configuration 27
Access the System Remotely
You can configure the S4820T system to be accessed remotely by T elnet. The
system has a dedicated management port and a management routing table that is
separate from the IP routing table.
To access the system remotely, follow these steps:
Step Task
1 Configure an IP address for the management port (
Port IP Address
2 Configure a management route with a default gateway (

).
Configure the Username and Password
Configure the Management Port IP Address
In order to access the system remotely, assign IP addresses to the management
ports.
To assign IP addresses to the management ports, follow these steps:
Step Task Command Syntax Command Mode
1 Enter INTERFACE
mode for the
Management port.
2 Assign an IP address
to the interface.
3 Enable the interface. no shutdown INTERFACE

CONFIGURATION
28 Performing the Initial Configuration
Configure the Management Route
Define a path from the S4820T to the network from which you are accessing the
S4820T remotely. Management routes are separate from IP routes and are used
to manage the S4820T through the management port.
To configure a management route, follow this step:
Task Command Syntax Command Mode
Configure a
management route to
the network from
which you are
accessing the system.
management route ip-address/mask
gateway
CONFIGURATION
Configure the Username and Password
To access the system remotely, configure a system username and password.
To configure a username and password, follow this step:
Task Command Syntax Command Mode
Configure a username
and password to
access the system
remotely.
username username [encryption-type]
password
CONFIGURATION
Configure the Enable Password
Access EXEC Privilege mode using the enable command. EXEC Privilege
mode is unrestricted by default. As a basic security measure, configure a
password. There are two types of enable passwords:
• enable password—stores the password in the running/startup configuration
using a data encryption standard (DES)-encryption method.
• enable secret—stores the running/startup configuration using a stronger,
MD5-encryption method.
Dell Force10 recommends using the enable secret password.
Performing the Initial Configuration 29
To configure the enable secret password, follow this step:
Task Command Syntax Command Mode
Create a password to
access EXEC
Privilege mode.
enable [password | secret] [level level]
[encryption-type] password
CONFIGURATION
Create a Port-based VLAN
The Default VLAN (VLAN 1) is part of the system startup configuration and
does not require configuration. To configure a port-based VLAN, you must
create the VLAN and then add physical interfaces or port channel (LAG)
interfaces to the VLAN.
To create a port-based VLAN, follow this step:
Task Command Syntax Command Mode
Configure a port-based VLAN (if the
vlan-id is different from the Default
VLAN ID) and enter INTERFAC E
VLAN mode. After you create a
VLAN, you must assign interfaces in
Layer 2 mode to the VLAN to activate
the VLAN.
To view the configured VLANs, use the show vlan command in EXEC
Privilege mode.
interface vlan vlan-id CONFIGURATION
Assign Interfaces to a VLAN
Y ou can only assign interfaces in Layer 2 mode to a VLAN using the tagged and
untagged commands. To place an interface in Layer 2 mode, use the switchport
command.
You can designate Layer 2 interfaces as tagged or untagged. When you place an
interface in Layer 2 mode using the switchport command, the interface is
automatically designated untagged and placed in the Default VLAN.
30 Performing the Initial Configuration
To view which interfaces are tagged or untagged and to view which VLAN the
interfaces belong, use the show vlan command. To view just the interfaces that
are in Layer 2 mode, use the show interfaces switchport command in EXEC
Privilege mode or EXEC mode.
To tag frames leaving an interface in Layer 2 mode, you must assign that
interface to a port-based VLAN to tag it with that VLAN ID.
To tag interfaces, follow these steps:
Step Task Command Syntax Command Mode
1 Access the
INTERF ACE VLAN
mode of the VLAN to
which you want to
assign the interface.
2 Enable an interface to
include the IEEE
802.1Q tag header.
interface vlan vlan-id CONFIGURATION
tagged interface INTERFACE
Use the untagged command to move untagged interfaces from the Default
VLAN to another VLAN:
To move untagged interfaces, follow these steps:
Step Task Command Syntax Command Mode
1 Access the
INTERF ACE VLAN
mode of the VLAN to
which you want to
assign the interface.
2 Configure an interface
as untagged. This
command is available
only in VLAN
interfaces.
interface vlan vlan-id CONFIGURATION
untagged interface INTERFACE
Performing the Initial Configuration 31
Assign an IP Address to a VLAN
VLANs are a Layer 2 feature. For two physical interfaces on different VLANs
to communicate, you must assign an IP address to the VLANs to route traffic
between the two interfaces. The shutdown command in INTERFACE mode
does not affect Layer 2 traffic on the interface.
NOTE: You cannot assign an IP address 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.
To assign an IP address to a VLAN, follo w th is step:
Task Command Syntax Command Mode
Configure an IP address
and mask on the interface.
ip address ip-address mask

Connecting the S4820T to the Network
After you have completed the hardware installation and software configuration
for the S4820T system, you can connect to your company network by following
your company’s cabling requirements.
