Product Description
S4820T is a top-of-rack (ToR) switch/router product for copper connections to
10G servers and 40Gbps uplinks to the 40G switching fabric in the core. The
S4820T has 48 ports of 10GBase-T and four ports of 40Gbps with features and
functions similar to the S4810 product.
The S4820T switch runs the Dell Force10 Operating System (FTOS), providing
switching, bridging, and routing functionality for transmitting data, storage, and
server traffic.
In a data center network, the S4820T switch provides converged network
support and interoperates with Dell and third-party ToR devices. The switch
supports
data center bridging (DCB) features and optimizes connectivity
between servers and storage devices using Fibre Channel over Ethernet
(FCoE) and Internet Small Computer System Interface (iSCSI) links.
By providing increased 40GbE bandwidth for device interconnection in a
shared network storage environment, with the possibility of splitting 40GbE
Quad Small Form-Factor Pluggable Plus (QSFP+) uplinks into 10GbE SFP+
connections, the S4820T switch is perfectly positioned to help transition a
data center with multiple speed requirements.

container.
2 Open the container or remove the container top.
3 Carefully remove the switch from the container and place it on a secure and
clean surface.
4 Remove all packing material.
5 Inspect the product and accessories for damage.

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

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
1Remove the PSU slot cover from the S4820T (PSU side of switch), either of the
two PSU slots may be selected.
2Remove 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.
4Plug 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).
5If 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.
