Product Overview

The Dell 1082DS/2162DS/4322DS Remote Console Switch (RCS) digital
keyboard, video and mouse (KVM) over IP and serial console switches combine
analog and digital technology to provide flexible, centralized control of data
center servers, and to facilitate the operations, activation, and maintenance of
remote branch offices where trained operators may be unavailable. The IP-based
RCS gives you flexible target device management control and secure remote
access from anywhere at anytime through the RCS software or on-board web
interface (OBWI).

Features and Benefits

The RCS provides enterprise customers with the following features and options:

• significant reduction of cable volume

• Virtual Media (VM) capabilites, configurable for analog (local) or digital
(remote) connectivity

• smart card/Common Access Card (CAC) capability

• true serial capability through Secure Shell (SSH) and Telnet

• enhanced video resolution support, up to 1600 x 1200 or 1680 x 1050
(widescreen) native from target to remote

• optional dual power models for redundancy

• optional support for managing intelligent power devices

• dual independent local port video paths (dedicated to ACI)

Product Overviewxxx | xxx1

• dual stack IPv4 (DHCP) and IPv6 (DHCPv6 and stateless auto­configuration) for simultaneous access

• accessibility to target devices across 10/100/1000BaseT LAN ports.

• a MODEM port that supports V.34, V.90 or V.92-compatible modems that
may be used to access the switch when an Ethernet connection is not
available

• FIPS support

Reduce Cable Bulk

With server densities continually increasing, cable bulk remains a major concern
for network administrators. The RCS significantly reduces KVM cable volume in
the rack by utilizing the innovative Server Interface Pod (SIP) modules and
single, industry-standard Unshielded Twisted Pair (UTP) cabling. This allows a
higher server density while providing greater airflow and cooling capacity.

KVMSwitching Capabilities

The RCS supports SIPs that are powered directly from the target device and
provide Keep Alive functionality when the switch 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 the 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 RCS is offered with 8, 16, or 32
Analog Rack Interface (ARI) ports for connecting SIPs. Utilizing the SIP, you
can attach additional switches to expand your RCS system. This flexibility
allows you to add capacity as your data center grows.

Multiplatform Support

The Dell SIPs are available for use with the RCS to support PS/2, USB, USB2,
and USB2+CAC device environments. Using the OBWI in conjunction with
these modules allows you to switch easily across platforms.

2xxx | Product Overviewxxx

Interoperability with Avocent® IQ Module Intelligent Cabling may also be used
to connect devices to the RCS. PS/2, USB, Sun®, and serial 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..

True Serial Capabilities

The RCS supports SIPs that provide true serial capabilities through Telnet.
With a SIP, you can launch an SSH session or launch a serial viewer from the
OBWI to connect to serial targets that are connected to an RCS.

Local and Remote User Interfaces

You can use the local user interface (local UI) by connecting directly to the local
port to manage the RCS. You can also use the remote OBWI to manage your
switch. The OBWI is web browser based and is launched directly from the
switch, and any devices connected to the switch are automatically detected.

Virtual Media and Smart Card-capable Switches

The RCS allows you to view, move, or copy data located on virtual media to and
from any target device. You can manage remote systems more efficiently by
allowing operating system installation, operating system recovery, hard drive
recovery or duplication, BIOS updating, and target device backup.

The RCS also allows you to use smart cards in conjunction with your switch
system. Smart cards are pocket-sized cards that store and process information.
Smart cards such as the CAC can be used to store identification and
authentication to enable access to computers, networks, and secure rooms or
buildings.

Virtual media and a smart card reader can be connected directly to the USB
ports on the switch. In addition, virtual media and smart card readers may be
connected to any remote workstation that is running the remote OBWI, Dell
RCS software, or Avocent management software and is connected to the switch
using an Ethernet connection.

Product Overviewxxx | xxx3

NOTE: To open a virtual media or smart card session with a target device,
you must first connect the target device to a switch using a SIP.

On-board Web Interface

The OBWI provides similar management functions as the RCS software, but
does not require a software server or any installation. The OBWI is launched
directly from the switch, and any servers connected to the RCS are
automatically detected. You can use the OBWI to configure the RCS from a
web browser. Launch the Viewer from the OBWI to establish KVM and virtual
media sessions to target devices. The OBWI also supports LDAP
authentication, which allows permissions for multiple RCSs to be managed
through a single interface.

Access the Switch Using a Standard TCP/IP Network

The switch provides agentless remote control and access. No special software or
drivers are required on the attached servers or client.

NOTE: The client connects to the switch using an Internet browser.

You can access the switch and all attached systems via Ethernet or using a V.34,
V.90, or V.92 modem from a client. The clients can be located anywhere a valid
network connection exists.

Encryption

The RCS supports 128-bit SSL(ARCFOUR), as well as AES, DES, and 3DES
encryption of keyboard/mouse, video, and virtual media sessions.

Video

The RCS provides optimal resolution for analog VGA, SVGA, and XGA video.
You can achieve resolutions up to 1600 x 1200 or 1680 x 1050 (widescreen),
depending on the length of cable separating your switch and servers.

4xxx | Product Overviewxxx

Flash Upgradeable

Upgrade your RCS and SIPs at any time to ensure you are always running the
most current firmware version available. Flash Upgrades can be initiated through
the OBWI or the serial console. The RCS can be configured to perform
automatic firmware upgrades of SIPs. See "Upgrading RCS Firmware" on page
52 for more information.

Tier Expansion

The RCS features allow you to tier additional Dell RCSs from each of the
Analog Rack Interface (ARI) port on the switch. The tiered switches are
attached in the same manner as any device. This additional tier of units allows
you to attach up to 1024 servers in one system. See "Adding a Tiered Switch" on
page 31.

Avocent Management Software Plug-in

Avocent management software may be used with the switch to allow IT
administrators to remotely access, monitor, and control target devices on
multiple platforms through a single, web-based user interface. For more
information, see the Technical Bulletin for the Avocent management software.

FIPS cryptographic module

The RCS switches support FIPS 140-2 Level 1 cryptographic security
requirements. The FIPS mode of operation can be enabled or disabled via the
OBWI or local port and executed after a reboot. When FIPS is enabled, a reboot
of the switch requires approximately two additional minutes to complete a FIPS
mode integrity check. Also, when FIPS is enabled, if the keyboard, mouse or
video encryption is set to 128-bit SSL (ARCFOUR) or DES, the encryption
level is automatically changed to the encryption level AES.

NOTE: The FIPS mode of operation is initially disabled and must be enabled
to operate.

NOTE: The Setup port factory default setting will automatically disable the
FIPS module.

Product Overviewxxx | xxx5

NOTE: The FIPS mode can be changed via the DSView software plug-in.

RCS switches use an embedded FIPS 140-2 validated cryptographic module
(Certificate #1051) running on a Linux PPC platform per FIPS 140-2
Implementation Guidance section G.5 guidelines.

The FIPS mode can be enabled/disabled via the OBWI, Local Port, or DSView
plug-in. A reboot is required to enable or disable FIPS mode. A firmware upgrade
to this version or setting the state to the default state (Setup Port menu) will
disable FIPS mode.

In FIPS mode, encryption ciphers are restricted to AES or 3DES. When FIPS is
enabled, if the Keyboard/Mouse or Video encryption is set to 128-bit SSL or
DES, the encryption level is automatically changed to AES. With FIPS enabled,
these files are saved (or restored) using a FIPS compatible algorithm, AES.
When FIPS is disabled, the User Database and Appliance Configuration files
saved from or restored to the appliance as external files are encrypted (or
decrypted) using DES.

This is true even when the user does not fill in the Password parameter in the
Save (or Load) dialog on the OBWI, in which case a default OEM password is
used for encryption or decryption.

One result of enabling the FIPS module is to render previously saved User
Database and Appliance Configuration files incompatible. In this case, you may
temporarily disable the FIPS module, reboot the appliance, restore the previously
saved database or configuration file, re-enable the FIPS module, reboot, and then
save the file externally again while the FIPS module is enabled. The new saved
external file will be compatible with the appliance as long as the appliance is
running with FIPS mode enabled.

The opposite situation is also true, in that database and configuration files
saved with FIPS module enabled are not compatible for restoring to an
appliance without the FIPS module enabled or an appliance with older firmware
not supporting the FIPS module.

Installation

The RCS transmits KVM and serial information between operators and target
devices connected to the switch over a network using either an Ethernet or
modem connection. The RCS uses TCP/IP for communication over Ethernet.
For the best system performance, use a dedicated, switched 100BaseT or
1000BaseT network. You can also use 10BaseT Ethernet.

The RCS uses the Point-to-Point Protocol (PPP) for communication over a
V.34, V.90, or V.92 modem. You can perform KVM and serial switching tasks by
using the OBWI or the Avocent management software. For more information on
the Avocent management software, visit http://www.avocent.com.

The RCS box includes the RCS, RCS software, and the OBWI. You may choose
to use either the RCS software or the OBWI to manage your system. The
OBWI manages a single RCS and its connections, while the RCS software can
manage multiple switches and their connections. If you plan to use only the
OBWI, you do not need to install the RCS software.

NOTE: The RCS software can be used to manage some switches. For more
information, please refer to the appropriate installer/user guide for your
product.

NOTE: Please ensure that all your RCSs have been upgraded to their most
recent version of Firmware. For information on upgrading an RCS through the
OBWI, refer to "RCS Tools" on page 52.

RCS Quick Setup

The following is a quick setup list. To begin by mounting the RCS in a rack and
for detailed installation instructions, see "Getting Started" on page 15.

Installationxxx | xxx13

1 Adjust mouse acceleration on each server to Slow or None.

2 Install the RCS hardware, and connect a Server Interface Pod (SIP) or

Avocent® IQ module to each server or tiered switch. Connect each SIP or

Installationxxx | xxx15

NOTE: You cannot open a virtual media session or a CAC session if the
server is connected via a PEM.

Setting up Your Network

The switch uses IP addresses to uniquely identify the switch and the target
devices. The RCS supports both Dynamic Host Configuration Protocol
(DHCP) and static IP addressing. Make sure that an IP address is reserved for
each switch and that each IP address remains static while the switch is
connected to the network.

Keyboards

A USB keyboard and mouse may be connected to the analog port of the RCS.

NOTE: The RCS also supports the use of multiple keyboards and multiple
mice on the analog port. The use of more than one input device
simultaneously, however, may produce unpredictable results.

Rack Mounting the RCS

You may either place the RCS 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, 1U rear­rack, 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 RCS. In addition, one mounting bracket is provided for 0U configurations,
and one blanking panel is provided for rear-rack installations.

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 equipment and possible personal injury.

16xxx | Installationxxx

Stabilize racks in a permanent location before loading begins. Mount
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.

Installing the Dell ReadyRails™ System

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

1U Tool-less 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 2.1, item 1 and its extractions illustrate
how the pegs appear in both the square and unthreaded round holes.

Installationxxx | xxx17

Figure 2.1: 1U Tool-less Configuration

2 Align and seat the front flange pegs in the holes on the front side of the

vertical post (item 2).

3 Repeat this procedure for the second rail.

4 To remove each rail, pull on the latch release button on each flange ear

(item 3) and unseat each rail.

Two-post Flush-mount Configuration

1 For this configuration, the castings must be removed from the front side of

each ReadyRails assembly (Figure 2.2, item 1). Use a Torx™ driver to
remove the two screws from each front flange ear (on the device side of the
rail) and remove each casting. Retain castings for future rack requirements.
It is not necessary to remove the rear flange castings.
