Product Overview
The Dell 1081AD/2161AD Server Console Switch (SCS) is an analog keyboard,
video, and mouse (KVM) switch that provides flexible, centralized local access
to data center servers. It can also provide centralized remote access to data
center servers when used in conjunction with the optional Remote Access Key
(RAK).
Features and Benefits
Reduce Cable Bulk
With device densities continually increasing, cable bulk remains a major concern
for network administrators. The SCS significantly reduces KVM cable volume in
the rack by utilizing the innovative Server Interface Pod (SIP) and single,
industry-standard Unshielded Twisted Pair (UTP) cabling. This allows a higher
device density while providing greater airflow and cooling capacity.
SIP Intelligent Modules
The SCS supports SIPs that are powered directly from the target device and
provide Keep Alive functionality when the SCS is not powered. The SIPs with
CAT 5 design dramatically reduce cable clutter while providing optimal
resolution and video settings. The built-in memory of SIPs simplifies
configuration by assigning and retaining unique device names and Electronic ID
(EID) numbers for each attached device.
PS/2 and USB SIPs are available allowing direct KVM connectivity to devices.
The USB2+CAC SIP is also available. The SCS is offered with 8 or 16 ARI
Product Overviewxxx | xxx1
ports that are used to connect SIPs to the SCS. Then utilizing the SIPs, you can
attach additional switches to expand your SCS system. This flexibility allows
you to add capacity as your data center grows.
Multiplatform Support
Dell SIPs are available for use with the SCS to support PS/2, USB, USB2, and
USB2+CAC device environments.
Interoperability with Avocent®IQ Module Intelligent Cabling may also be used
to connect local devices to the SCS. PS/2, USB, and Sun®module options are
available. For more information, please refer to the appropriate Avocent
installer/user guide for your product or visit avocent.com/manuals for more
information.
User Interfaces
The SCS is equipped with two “point-and-click” interfaces to manage the SCS
locally. They are the local user interface (UI), referred to as OSCAR™, and the
on-board web interface (OBWI). Using the configuration options provided by
these interfaces, you can tailor your SCS to your specific application. The
OBWI can also be used to access and control any attached devices, and handle
all basic KVM needs remotely.
NOTE: Remote KVM sessions via the OBWI requires the installation of the Dell RAK.
OSCAR Interface
The OSCAR interface, accessed using the local port, features intuitive menus
and operation modes to configure your SCS and devices. Devices can be
identified by name, EID, or port number.
The OSCAR interface allows you to protect your system with a screen saver
password. When the screen saver mode engages, access is prohibited until the
appropriate password is entered to reactivate the system. By typing Help in the
password dialog, you are directed to Dell Technical Support. Recommended
usage for the SCS is in a data center infrastructure protected by a firewall.
2xxx | Product Overviewxxx
OBWI
You can also use the OBWI to manage your SCS. The OBWI is launched
directly from the SCS and does not require a software server or any installation.
With the addition of the optional Dell RAK installed, you can also establish
remote KVM and virtual media sessions to target devices. For more information,
see "Dell Remote Access Key (RAK)" on page 4.
Terminal Console Interface
The terminal console interface is accessed through the "10101" setup port. A
terminal screen or a PC running terminal emulation software can be used to
access these screens.
Virtual Media and Smart Card-capable Switches
The SCS allows you to view, move, or copy data located on local media and
smart cards. Smart cards are pocket-sized cards that store and process
information including identification and authentication information to enable
access to computers, networks, and secure rooms or buildings.
A virtual media or a smart card reader can be connected directly to the USB
ports on the SCS. In addition, virtual media or smart card readers may be
connected to any remote workstation that is running the remote OBWI, SCS
Software, or Avocent management software, and is connected to the SCS using
an Ethernet connection.
NOTE: To open a virtual media or smart card session with a target device, you must
first connect the target device to an SCS using a USB 2.0 or USB+CAC SIP.
IPv4 and IPv6 Capabilities
The SCS is compatible with systems using either of the currently used Internet
Protocol Versions, IPv4 or IPv6. You can change the network settings and
choose either IPv4 or IPv6 mode via the terminal console, OSCAR interface, or
OBWI.
Product Overviewxxx | xxx3
Access the SCS Using a Standard TCP/IP Network
The device is accessible for configuration via the standard TCP/IP Network. If
the optional Dell RAK is installed, you can access all attached systems via
Ethernet. See "Dell Remote Access Key (RAK)" on page 4.
NOTE: The client connects to the SCS using an Internet browser.
NOTE: KVM over IP sessions are supported when the Dell RAK is installed.
Upgradeable
Upgrade your SCS and SIPs at any time to ensure you are always running the
most current firmware version available. Upgrades can be initiated through the
OSCAR interface, OBWI, or the terminal console screens. The SCS can also be
configured to perform automatic firmware upgrades of SIPs. For more
information, see "Tools - Rebooting and Upgrading" on page 65.
Two-tier Expansion
The SCS allows you to tier one additional SCS, CS, or RCS from each ARI port
on the primary SCS. Each tiered SCS is attached in the same manner as any
device. This additional tier of units allows you to attach up to 512 servers in
one system. See "Tiering Your Switch Using a SIP" on page 26.
Dell Remote Access Key (RAK)
The optional Dell RAK, installed in the USB port, supports the following
features.
KVM Remote Access
A single KVM remote user is supported using the RAK. With the RAK, you can
manage remote operating system installation, operating system recovery, hard
drive recovery or duplication, BIOS updating, and server backup.
4xxx | Product Overviewxxx
Avocent Management Software Plug-in
Avocent management software may be used with the SCS to allow IT
administrators to securely and remotely access and monitor target devices on
multiple platforms through a single, web-based user interface. A session may be
launched to a device from a single point of access. For more information, see the
Technical Bulletin for the management software plug-in.
Local Video Scaling
The SCS digitizes a video signal with a maximum pixel resolution of up to 1600
x 1200 or 1680 x 1050 (widescreen), depending on the length of cable separating
your SCS and devices.
Encryption
The SCS supports 128-bit SSL(ARCFOUR), AES, DES, and 3DES encryption
of keyboard/mouse, video, and virtual media sessions.

Rack Mounting Safety Considerations
• Rack Loading: Overloading or uneven loading of racks may result in shelf or
rack failure, causing damage to equipment and possible personal injury.
Stabilize racks in a permanent location before loading begins. Mount
14xxx | Installationxxx
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 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 room
ambient. Use care not to exceed the 50°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 supply connections other than direct
connections to the branch circuit (for example, use of power strips).
• Product should not be mounted with the rear panel facing in the downward
position.
