12 Installation

Power Supplies

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 wil l 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 correctly, excessive emissions
may result. Use a qualified electrician to ensure the power cables meet your
local electrical require ments.

Installation 13

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.

NOTE: The system powers up as soon as the cables are connected between the

power supply and the power source.

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.

14 Installation

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

°

C maximum

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.

Installation 15

Installing the Dell ReadyRails System

The ReadyRails rack mounting system is provided to easily configure your
rack for installation of your switch. The ReadyRails system can be installed
using the 1U tool-less method or one of three possible 1U tooled methods
(two-post flush mount, two-post center mount, or four-post threaded).

1U Tool-l ess Configuration (Four-post Square Hole or Unthreaded Round
Hole):

1

With the ReadyRails flange ears facing outward, place one rail between the
left and right vertical posts. Align and seat the rear flange rail pegs in the
rear vertical post flange. In Figure 1-5, item 1 and its extractions show how
the pegs appear in both the square and unthreaded round holes.

Figure 1-5. 1U Tool-less Configuration

To remove each rail, pull on the latch release button on each flange ear and
unseat each rail. Refer to Figure 1-5, item 3.

16 Installation

Two-post Flush-mount Configuration:

1

For this configuration, you must remove the castings from the front side of
each ReadyRails assembly. Refer to Figure 1-6, item 1. Use a Torx driver to
remove the two screws from each front flange ear (on the switch side of the
rail) and remove each casting. Retain the castings for future rack
requirements. It is not necessary to remove the rear flange castings.

Figure 1-6. Two-post Flush-mount Configuration

2

Attach one rail to the front post flange with two user-supplied screws.
Refer to Figure 1-6, item 2.

3

Slide the plunger bracket forward against the vertical post and secure the
plunger bracket to the post flange with two user-supplied screws. Refer
to Figure 1-6, item 3.

Installation 17

with two user-supplied screws. Refer to Figure 1-7, item 2.

3

Repeat this procedure for the second rail.

18 Installation

Four-post Threaded Configuration:

1

For this configuration, you must remove the flange ear castings from each
end of the ReadyRails assemblies. Use a Torx driver to remove the two
screws from each flange ear and remove each casting. Refer to Figure 1-8,
item 1. Retain the castings for future rack requirements.

2

For each rail, attach the front and rear flanges to the post flanges with two
user-supplied screws at each end. Refer to Figure 1-8, item 2.

Figure 1-8. Four-post Threaded Configuration

Installation 19

Installing the Switch

You can mount the switch in the 1U front-rack or 1U two-post (flush and
center) configurations. The following is an example of a 1U front-rack
configuration. For the 1U two-post (flush and center) configurations, you can
slide the switch into the rails in the same manner as the four-post
configurations.

1U Front-rack Installation

You must configure the rails that are attached to the switch.

1

Attach the switch rails (inner chassis members) to the S4820T switch.
Figure 1-9, item 1 shows the detail for the front standoff with the locking
tab.

Figure 1-9. Attaching the Switch Rails

20 Installation

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 Laye r 2 mo de, follow these steps:

To view the interfaces in Layer 2 mode, use the show interfaces switchport
command in EXEC mode.

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:

1 Enable the interface. no shutdown INTERFACE
2 Place the interface in

Layer 2 (switching)
mode.

Access the System Remotely

You can configure the S4820T system to be accessed remotely by Telnet. 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:

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 T ask

1 Configure an IP address for the management port (

Configure the Management

Port IP Address

).

2 Configure a management route with a default gateway (

Performing the Initial Configuration 29

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 manageme nt route, follow this step:

Configure the Username and Password

To access the system remotely, configure a system username and password.
To configure a username and password, follo w this step:

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.

To configure the enable secret password, follow this step:

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:

To view the configured VLANs, use the show vlan command in EXEC
Privilege mode.

Assign Interfaces to a VLAN

You can only assign interfaces in Layer 2 mode to a VLAN using the tagged and
untagged commands. T o 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.

Task Command Syntax Command Mode

Create a password to
access EXEC
Privilege mode.

enable [password | secret] [level level]

CONFIGURATION

Task Command Syntax Command Mode

Configure a port-based VLAN (if the
vlan-id is different from the Default
VLAN ID) and enter INTERFACE
VLAN mode. After you create a
VLAN, you must assign interfaces in
Layer 2 mode to the VLAN to activate
the VLAN.

interface vlan vlan-id CONFIGURATION

Performing the Initial Configuration 31

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:

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

INTERFACE VLAN

only in VLAN
interfaces.

32 Performing the Initial Configuration

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, follow this step:

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.
