Chapter 1. ClearCube I/Port Overview

The ClearCube architecture delivers PC functionality to the desktop from a secure, centralized
location. This results in dramatic increases in manageability and security while providing
mission-critical reliability, performance, and uptime improvements with lowered costs.
Replacing a traditional PC box with a ClearCube C/Port or I/Port in an office or cubicle also
saves space, eliminates fan noise and simplifies cabling resulting in a clear cube. The key
components of the ClearCube Architecture are:

• Host or Blade – a remotely-located computer in a dense form factor.

• Chassis – a centralized host or blade housing that provides the power for each host and

accepts a wide variety of chassis modules.

• Chassis Module – a modular interface card that plugs into a chassis and provides

thin client, management, and network connections.

• Thin Client – a remote desktop unit (C/Port or I/Port) to which standard peripherals are

connected.

• System Management – Sentral™ system management software and monitoring hardware

that is built into ClearCube blades, ClearCube chassis, and ClearCube I/Ports.

The ClearCube I/Port is a thin client that connects to hosts over a standard Ethernet network.
The I/Port delivers video and peripheral signals to a local user from a centralized host using
Ethernet protocol, allowing it to work over standard switched networks. Unlike ClearCube
C/Ports, I/Ports do not require point-to-point connections to hosts (homerun cabling is not
required).

The I/Port enables IT managers use existing IP networks and cabling infrastructure, regardless
of the distance between users' desktops and their centralized hosts.

This guide describes the following I/Ports:

• I8020 – NeoLinux

• I8820 – Windows

• I8330 – OS-independent

• I9420 – OS-independent

• I9440 – OS-independent

Thin Clients and Operating Systems

ClearCube I/Ports are available with:

• Windows XPe operating system—Windows XPe offers the power of Windows XP in a

compact, componentized form.

• Neoware NeoLinux operating system—NeoLinux is a tailored version of Linux

targeted at and optimized for a broad range of information appliances and thin clients.
NeoLinux features a secure, read-only file system that enabling applications run on the
host, not on the local thin client. Neoware employs a hardened default security profile and
a streamlined user security environment.

Both operating systems have the advantage of being remotely manageable using
ClearCube Sentral and Neoware ezRemote Manager software.

• PCoIP™ processors—Enable thin clients to deliver a high-end PC experience to multiple

monitors over a standard network, without an operating system. PCoIP also transparently
redirects USB from the thin client to the host, or computing device. ClearCube I9xx
I/Ports use PCoIP processors.

I8820

I8020

The I8820 features Windows XPe as the operating system. The small form factor of the I8820
I/Port allows customers to easily mount the I8820 under desks, vertically on walls, or behind a
monitor using the optional mounting bracket.

Connecting to hosts using RDP, the I8820 I/Port delivers video and peripheral signals to users
using Ethernet, eliminating distance limitations between hosts and users. The I8820 supports
ClearCube Sentral, which sets up and dynamically allocate the RDP connections between the
I/Ports and hosts. Additionally, Sentral provides sparing and dynamic allocation capabilities
for ClearCube I/Ports.

The I8020 runs an embedded Linux operating system called NeoLinux. The I8020 features the
same form factor as the I8820, allowing the same flexibility in mounting at the user’s work
space.

Like the I8820, the I8020 eliminates any distance limitations between the host and the user by
using RDP. Hosts running Windows XP can work with the NeoLinux-based I8020 without
requiring any upgrades. The I8020 also supports Sentral.

I8330

The I8330 connects over Ethernet and does not use RDP as the extension prot ocol. Because
this technology eliminates the need for an operating system on the desktop device, I8330
I/Ports significantly reduce the likelihood of viruses on thin clients.

I9420 and I9440

The I9420 I/Port and the I9440 I/Port use PCoIP processors to deliver simultaneous full
screen, full motion video at high resolutions on the following numbers of monitors:

• I9420—One or two monitors when connected to hosts containing V5120 Dual Host video cards

• I9440—One to four monitors when connected to hosts containing V5140 Quad Host video cards

You can specify a different resolution and display orientation (portrait or landscape) for each
monitor connected to an I94xx I/Port.

You can deploy I9420 and I9440 I/Ports on:

• Existing Ethernet networks

• Secure point-to-point connections to prevent desktop-display data commingling with other
network traffic

I94xx I/Ports do not require unique OS drivers, and support the following standard
peripherals:

• Multiple monitors

• Keyboards

• Mouse devices

• Audio devices

• USB peripherals, including isochronous USB devices

Supporting Technology and Software

The following applications work together to enable and enhance I/Port functionality:

• Remote Desktop Protocol (RDP)

• ClearCube Sentral

•Neoware ezRemote Manager

• I83xx Driver and Admin Utility

• PC-over-IP™ (PCoIP) technology

Remote Desktop Protocol

Microsoft Remote Desktop Protocol (RDP) is a presentation protocol that allows the I/Port to
communicate with a host. RDP works across any TCP/IP connection, such as a local area
network (LAN), wide area network (WAN), or virtual private network (VPN) connection.
RDP is the delivery mechanism for video, mouse, keyboard, and USB communications
between the I/Port and the host.

When using Remote Desktop Protocol from the I/Port, many of the local I/Port resources are
available within the session, for example:

• Peripheral Redirection – Peripherals connected to a local I/Port appear as if they are
connected to a user's host. RDP supports redirection for devices such as:

– Human Interface Devices (such as keyboards and pointing devices)
– TWAIN devices (such as scanners)
– Local drives (such as mass storage devices)
–Printers

– Devices attached the I/Port’s local serial port and parallel port

• Audio – The audio streams, such as .wav and .mp3 files, play through the I/Port’s

speaker connection. RDP provides downstream audio only. RDP only supports audio out
(i.e., from the host to the I/Port) so speakers connected to an I/Port can play sound
generated by the host. However, audio in (i.e., from the I/Port to the host) isn't supported
by RDP so audio devices such as microphones cannot transmit back to the host.

ClearCube Sentral

ClearCube Sentral provides IT administrators with a comprehensive set of features and
functionality for managing their I/Port environments. Sentral can optimize hardware
utilization by dynamically allocating I/Ports to a defined pool of hosts.

Sentral tracks host loading statistics and automatically initiates a connection to the least
utilized host when each user logs on. Power users can be mapped to an individual host
ensuring maximum performance. Auto discovery of I/Ports and hosts makes it easy to
inventory and manage assets. In addition, an update feature makes it easy to update the Sentral
Client on each I/Port when new software versions are made available. Finally, Sentral delivers
server-level availability to end users by enabling Administrators to easily switch an I/Port user
to a spare host should they experience a problem.

Neoware ezRemote Manager Software

Neoware ezRemote Manager is a remote management tool for keeping I/Ports up-to-date and
is used as a companion to Sentral. ezRemote Manager is based on a straightforward,
easy-to-use interface that allows administrators to remotely push drivers, applications, and
security updates via snap-ins, to a single I/Port or an entire enterprise. Snap-ins are
deployment packages that can automatically install peripheral drivers or local applications
such as VPN clients. ezRM can fully re-image a device in order to deploy a customized image
enterprise-wide or for disaster recovery on individual devices. ezRM is also the tool for
keeping XPe based units up-to-date with Microsoft security updates.

I83xx Driver and Admin Utility

The I83xx driver and the I83xx admin utility enable support for I83xx–series I/Ports in a
Sentral environment and are available on the Sentral installation CD.

Note: The I83xx driver and the I83xx admin utility are required only if you use I83xx I/Ports in

Each blade or virtual machine to which an I8330 connects must have the I83xx driver
installed. See Sentral Administrator’s Guide for more information about the I83xx driver and
the I83xx admin utility.

your environment. Ensure that you do not install I83xx drivers or admin utility on hosts
connected to I94xx I/Ports.

PCoIP

I9420 and I9440 I/Ports use PCoIP technology to deliver high–performance video and audio to
users. PCoIP technology consists of dedicated processors on the thin client (I94xx I/Port) and
on the host to which the thin client connects. ClearCube hosts can support I94xx I/Ports by
using one of the following host–side cards:

• V5120 Dual Host card—Contained in specific A–series and R–series PC blades to
support I9420 I/Ports

• V5140 Quad Host card—Contained in specific A–series PC blades to support I9440

Caution Statements

Improper connection, mounting, or use of this product could result in component failure or
undesired interference. Read the following caution statements before setting up and operating
your I/Port.

Setup

• Do not connect to AC power until all other connections are made, including the power

adapter. Connecting or disconnecting components or equipment on the back panel when
the I/Port is receiving AC power can cause power surges and damage the device.

• Do not force a connector into its socket. If any undue resistance is encountered, ensure that

the connector is correctly oriented to the receptacle.

• Do not attach the I/Port to a telephone jack or other powered network connection. This

will permanently damage the I/Port. This damage is not covered under the ClearCube
Technology limited warranty.

Orientation and Venting

• Allow sufficient space around the I/Port for ventilation. Do not place the device in any

enclosure that restricts airflow around the device. Do not place any objects on the device.
Product environmental specifications are listed in Appendix A. Specifications

• The I8020 and I8820 can be mounted horizontally or vertically. An optional mounting

bracket is available from ClearCube. Provide adequate clearanc e around the I/Port for
cooling.

• The I8330 can be mounted horizontally or vertically. Provide adequate clea rance around

the I/Port for cooling.

• Mount I9420 I/Ports and I9440 I/Ports flat (that is, horizontally). A mounting bracket is

included with each I9420 and I9440. See "Using the I94xx Mounting Bracket
for instructions about how to mount the bracket and for information about the minimum
clearance specifications.

Power Sources

• To e nsure regulatory compliance, use only the power supply included in the shipping
carton with the I/Port, or a ClearCube-approved equivalent.

• Surge protectors for electrical devices are recommended in areas of frequent lightning.
However, when lightning is occurring, your equipment should be properly shut down and
unplugged from AC power until the storm has passed.

• Be careful to not interrupt power while the I/Port is receiving a software update.

Cable Requirements

For I/Port installations, you need 16 CAT5 cables per chassis to connect the hosts to your
network switch. You will not need to connect any cables to the C/Port connections. With
I/Ports, the cables going to the desktop are connected directly to your network switch. Figure 3

3. Connect the power cord.

4. Press the power push-button on the I/Port to turn power on.

5. Enable any necessary ports on your switches and routers. Sentral uses ports 6502 UDP,

4001 UDP, 9000 TCP and 9000 UDP. RDP uses port 3389 TCP and port 139 UDP. Your
individual network may use other ports besides these. For more information about ports
you need to open in your environment, see Sentral Administrator’s Guide.

Note: If using DHCP, verify that name resolution is activated to detect

non-Windows-based systems and that the DNS server is registering the I/Port.

6. For I94xx I/Ports only: To ensure 100/full-duplex throughput between a V5120 or

V5140 card in a blade and an I94xx I/Port, set any network switches connecting the blade
and the I/Port to automatic negotiation. Explicitly setting a network switch to
100/full-duplex can cause throughput issues. If there are performance or throughput issues
after setting network switches to automatic negotiation, physically disconnect and then
reconnect the network cables to the switch.

Using the I94xx Mounting Bracket

Use the I94xx mounting bracket, included with I9420 and I9440 I/Ports, to mount an I94xx
I/Port under a desk. Use the following tools to mount the bracket:

• Phillips screwdriver

• Optionally, a drill to drill 3/32–inch pilot holes for the mounting bracket screws.

Note: ClearCube recommends attaching all cables to the I/Port, as described in "Setting up

the I/Port" on page 9, before inserting the I/Port into the bracket.

1. Use the four holes in the top of the bracket as a pattern to mark the surface (for example,
the underside of a desk) where you will attach the bracket. Ensure that:

– There is a minimum of 1 ½ inches of clearance on each side of the I/Port.
– There is a minimum of ¾–inch clearance above the I/Port.

3

– The bracket is inset a minimum of 2 inches from the front of the desk.

2. Optionally, use a drill to make 3/32–inch pilot holes in each of the bracket markings you just made.

3. Use the included wood screws to screw the bracket into the four holes. Ensure that you do
not overtighten the screws.

4. Align the grooves on the side of the I/Port with the bracket flanges and gently slide the
I/Port into the bracket until it snaps into place.

Note: To prevent overheating, do not stand the I/Port on either of its sides, and do not cover

any ventilation holes.

-- ­8

Configuring the Sentral Console for the I/Port Connection

In its default configuration, Sentral automatically detects I/Ports when they are connected to a
Sentral-managed network, but some additional configuration is required. To configure the
Sentral console for your I/Port connection, do the following:

1. If using I8330 I/Ports, install the I8330 admin utility on the host where Sentral console is
installed. The I8330 admin utility is located on the Sentral installation CD.

2. From the Sentral console, run a discovery to discover all thin clients (as described in

Sentral Administrator’s Guide). From the Setup > Configuration screen, ensure that the
Discovery Update Config drop-down menu is set to True. This setting pushes out

credentials for the Primary and Secondary Sentral servers to I/Ports (however, not to
I83xx I/Ports). If Discovery Update Config is set to False, right-click the thin client
(I/Port) icon in the Hierarchical view, and select Configure to manually specify the
Primary and Secondary servers.

3. From Sentral, add the I/Port to a Thin Client Group. See Sentral Administrator’s Guide for
more information about adding thin clients to thin client groups.

4. Allocate the Thin Client Group to a host, a host group, or a virtual machine. From the
Sentral main menu, click Connection Brokering > Allocation. The Connection
Brokering - Mappings screen is displayed.

For more information, see Sentral Administrator’s Guide.

12 •

Enabling RDP on Hosts for I/Port Connections

The Remote Desktop Protocol (RDP) is used to connect your I/Port to a host or blade running
Windows XP Professional. The I/Port and host can be located anywhere – across the hall,
across town, or across an ocean from each other – provided that you have network access from
the I/Port to the host, you have sufficient network bandwidth (> 50 Kbps for each I/Port), and
you have the appropriate permissions set up on the host.

Using ClearCube Sentral management software, you can initiate connections from I/Ports to
hosts. See Sentral Administrator’s Guide for installation and configuration details. You can
also initiate sessions directly from a I/Port by using the local RDP client connection tool.

To connect to a host from an I/Port, the host must first allow incoming RDP connections. To
set up the host for this, you need a C/Port to connect directly to the host.

1. From the host Start Me nu, click Start > Settings > Control Panel > System.

2. Click the Remote tab to open the Remote Desktop (RDP) configuration.

3. Select the Allow users to remotely connect to this computer option.

4. Click OK to save the configuration.

Note: Remote desktop access is not required for I8330 connections, but may be desirable

for administrative purposes.

Configuring the XPe I/Port

Access BIOS configuration options by pressing F2 during start-up.

Whenever you want to make any persistent changes to the I/Port, such as changing user
settings or installing new software, you need to disable the I/Port’s Write Filter before making
the change, and re-enable it after you have committed the change. The Write Filter is a
software feature that prevents any inadvertent or undesired writes to the Flash Drive where the
I/Port’s operating system and other software is stored.

The Write Filter displays an icon in the system tray. When the icon has a red dot, the Write
Filter is enabled, stopping you from writing to the Flash. When the icon has a green dot, the
Write Filter is disabled and you can go ahead and write to the Flash.

When you push software updates using ezRemote Manager software, the Write Filter is
managed automatically. See "Updating I/Port Software

To manage the Write Filter manually, you must be logged in as administrator. Double-click on
the Write Filter icon in the system tray and select Disable write filter to disable the Write

Filter icon in the system tray and select Commit changes to disk and enable write filter.
Your changes are saved to Flash, the I/Port automatically restarts in 15 seconds, and the Write
Filter is re-enabled when the restart is complete.

The Sentral client is provided as the default client on both the XPe- and NeoLinux- based
I/Ports. When using your XPe-based I/Port as a client managed by Sentral, do the following
from the Sentral Console to begin configuring your I/Port for Sentral:

1. From the Sentral console, run a discovery to discover all thin clients (as described in

Sentral Administrator’s Guide). From the Setup > Configuration screen, ensure that the
Discovery Update Config drop-down menu is set to True. This setting pushes out

credentials for the Primary and Secondary Sentral servers to the I/Port. If Discovery
Update Config is set to False, right-click the thin client (I/Port) in the Hierarchical view,
and select Configure to manually specify the Primary and Secondary servers.

2. Add the I/Port to a Thin Client Group.

3. Allocate the I/Port or Thin Client Group to a host, a host group, or a virtual machine
(VM).

To log in directly to a host from an XPe-based I/Port, double-click the

on the I/Port to optimize the user experience. Most of the performance optimization revolves
around configuring RDP in the most appropriate fashion, given your infrastructure.

ClearCube recommends using the I/Port primarily on a corporate network (100Mbps or faster)
with Sentral. However, you may have users who will use I/Ports for remote applications, such
as office access from home, offshore development, etc.

RDP allows several configurable capabilities. Enabling each additional capability requires
more bandwidth, thus impacting performance. The ideal I/Port performance optimization
process will lead to the best possible experience within any limitations of your operating
environment.

Figure 9. Remote Desktop (RDP) Configuration Window

The following items can be configured prior to initiating an RDP connection:

• Display: Desktop Size – Though RDP allows the desktop to be sized so that the RDP

connection runs in a window smaller than the local XPe desktop, anything less than
full-screen mode is not recommended for I/Port users.

• Display: Color Depth – The color depth options range from 256 to T rue Color . Generally,

using only 256 colors negatively impacts the user experience, because most images are
grainy and low quality. 16-bit color is normally used.

also requires additional bandwidth.

If the user has limited bandwidth and does not require sound, this option can be
turned off.

Note: RDP only supports audio out (i.e., from the host to the I/Port) so speakers connected

to an I/Port can play sound generated by the host. However, audio in (i.e., from the
I/Port to the host) isn't supported by RDP so audio devices such as microphones
cannot transmit back to the host.

Figure 11. RDP Local Resources Tab

• Local Resources: Devices – RDP allows local disk drives, printers, and serial ports to be
redirected. Again, these require additional bandwidth. Large quantities of writes and reads
from local disks can adversely impact the performance of the RDP session.

to prevent any potential bandwidth loss caused by the

OS carrying out any

sort of detection or other processes for these devices.

• Experience – Selecting a connection speed causes specific items listed in the connection

speed pull-down menu to become checked or unchecked. Generally, the desktop
background, especially if it is an image, is a significant source of performance slowdowns.
The reason is that every time a window is moved within an RDP session, new parts of the
background get exposed and need to be re-transmitted. This is generally a slow and
time-consuming process. It is preferred, almost under any bandwidth conditions, to not
use a picture background.

Configuring the I9420 I/Port

ClearCube® I9420 I/Ports connect to ClearCube A1410 and R1350 PC blades to provide the
following features:

• Support for one or two independently–configurable monitors

• PC–over–IP™ (PCoIP™), delivering PC video and audio over your IP network

• Four USB 1.1 ports

• Audio in and HD audio out
ClearCube A1410 and R1350 PC blades contain V5120 Dual Host cards connected to the

blade’s PCI Express® connector. V5120 cards and I9420 I/Ports contain PCoIP processors
that manage video and audio data. When configuring and working with an I9420 I/Port
connected to a blade with a V5120 Dual Host card, remember that:

• There are two PCoIP processors:
– I9420 I/Port processor

22 •

– V5120 Dual Host card processor

• Each PCoIP processor has an IP address, for a total of two IP addresses. Note that the IP

addresses of the PCoIP processors are not the same as the host’s (that is, the computer’s)
IP address.

You must provision PCoIP processors on blades and on I942 0 I/Ports when dep loying I94 20s.
To provision an I9420, you must:

1. Determine the IP address structure for your environment and determine the IP addresses of

the blade, the V5120 Dual Host card, and the I9420 I/Port.

Best Practices for I/Ports

Follow the recommendations in this section for best I/Port performance.

RDP-Based I/Ports

As previously noted, RDP is a limited-bandwidth connection when compared to 100baseT
Ethernet. In addition, Ethernet bandwidth can be constrained by network activity anywhere
between each end of a connection.

•27

I/O-intensive applications between the host and the I/Port can significantly affect
performance. ClearCube offers these recommendations:

• Do not use I/Ports for writing to CDs or DVDs. Mass-storage devices such as CD
burners and DVD burners rely on a predictable and relatively constant data transfer rate
from the source to the burner. Although modern burners have large write buffers, the
likelihood of a buffer underrun is high, and increases both with recording speed and with
file size. If the user must write files from a host to CD or DVD, use the USB 2.0 connector
on the front of the ClearCube PC blade.

• Do not use I/Ports to transfer extremely large files. Although the I/Port provides robust
file transfer capabilities, the limited bandwidth inherent in RDP can cause these file
transfers take an exceedingly long time. If the user must write extremely large files to a
blade or to the network, use the USB 2.0 connector on the front of the ClearCube PC
blade.

• Do not write large files directly to I/Ports. The RAM disk on the XPe I/Port is limited to
16 MB, and is reserved as a temporary space for updating software on the I/Port. Attempts
to write a file larger than 16 MB to the RAM disk will fail. Attempts to write a series of
files with a sum file size greater than 16 MB will eventually fail when the 16 MB limit is
exceeded.

Individual files with a file size greater than 56 MB cannot be written through the I/Port to
an attached USB peripheral storage device. This is by design, and represents a security
feature that limits moving large files such as software. Folders containing multiple files,
with a total size greater than 56 MB can be written through, as long as the 56 MB limit is
not exceeded.

The Flash disk in the I/Port is write-protected by the Enhanced Write Filter. Writes to the C:\
drive, including temporary files, are written to an area in RAM that is separate from the RAM
disk and is shared by the operating system. When the sum of the files and the operating
system’s RAM requiremen t exceeds the total amount of av ailable RAM, the I/Port will suf fer
a system error. This can be c leared by rebo oting the I/Port. Ho wever, data in RAM cannot be
recovered.

28 •

• For normal usage, leave the Write Filter turned on. This prevents persistent writes to
the Flash disk and helps keep the device secure. Since applications are actually run on the
host in an I/Port environment, there is no need for the user to write data to the local I/Port.

• Upstream audio is not supported by RDP. Microphones can only be used as local
devices on the I/Port, and not as I/O devices to send content to the blade. This is a
limitation of RDP.

• Lengthy RDP sessions may result in slower throughput. If the connection through RDP
appears to have slowed down significantly, close the RDP session and restart the I/Port.

• Test your USB peripherals before putting them into a production environment.
I/Ports are USB 1.1 or USB 2.0 compliant, depending on model number. I/Port
peripherals, including USB devices, rely on redirection by RDP to work properly. RDP
can only redirect the following devices: mass storage, printers, serial ports and smart card
readers. ClearCube Technology maintains a list of peripherals (including USB devices)
that are fully tested and certified for use with ClearCube-supplied thin clients, including
I/Ports. This list is kept up-to-date and is available on the ClearCube Support Web site at

http://support.clearcube.com/

as Technical Bulletin TB0109, Certified Peripherals for

C/Ports and I/Ports. Because of the wide range of peripherals available, ClearCube is

unable to test all devices. If your peripheral is not on this list, contact your Account
Executive to ask about ClearCube certification services.

• Limit the number of USB peripherals connected to your I/Port. When connecting

more USB devices to an I/Port than there are available ports (three ports on the
I8020/I8820), you need a USB hub. You shou ld select a powered USB hub to reduce the
likelihood of drawing too much power from the I/Port's USB port(s). ClearCube has
observed unpredictable results when simultaneously attaching more than six USB devices
to an I/Port. USB devices with motors, such as CD-ROM or DVD drives, are the devices
most likely to exceed power ratings.

• Occasionally, USB devices fail to enumerate correctly when inserted or removed.

When inserting a device that supports RDP redirection into a peripheral port on the I/Port,
it should enumerate (display as a device on the host desktop). Allow a few seconds for this
to occur. If the device does not enumerate, try refreshing the desktop or the folder window.
This usually resolves the problem. If this does not work, check the system tray for the
device and eject it (if displayed), unplug the device, and then reattach it. Sometimes this
problem is caused by a USB device overloading the power rating for the I/Port's USB hub.
Using an externally powered USB hub will reduce this problem.

When removing a USB device, always eject it from the system tray and wait for
confirmation before physically unplugging it. If the device's icon persists on the desktop
after it has been physically removed, refresh the window or desktop. A reboot of the I/Port
may be required.

I8330 I/Ports

Because the I8330 I/Port requires a connection to be established via the I83xx Admin Utility
or I83xx Driver, certain limitations apply on the usage of I8330s as connection devices.

• Do not use an I8330 I/Port for administration duties. Use a C/Port or an

RDP-connected device (such as an I8820 I/Port or a traditional PC) for host
administration.

The I83xx driver software is supported only on Windows XP. Support on other operating
systems is not available, so the I8330 cannot be used to administrate a virtual m achine
(VM) host.

• Do not install the I83xx Driver on a system that also has the I83xx Admin Utility

installed. These two applications are incompatible, and using them on the same system
will cause unexpected results.

• Do not hot-plug PS/2 devices on an I8330 I/Port. On the I8330, PS/2 devices (keyboard

or mouse) are not hot-pluggable. You must turn off the I8330 before attaching or
detaching PS/2 devices.

• Disconnect USB devices using the “Safely Remove Hardware” icon in the system

tray. If USB devices are incorrectly disconnected, the USB chain is forced to
re-enumerate completely. This can cause a delay for the user, and will disrupt any
on-going USB communications (such as printer spooling or file transfer).

• USB devices are not available on the I8330 I/Port until a host connection is

established. Some USB keyboards and mice will function properly when connected using
a USB-to-PS/2 adapter.

•29

• The I8330 implements USB 1.1. Read and write performance are specified at 300KB/s
read and 200KB/s write.

• The I8330 does not support remote power on/off or reset functionality.

•

The I8330 is not capable of ru nning a VPN clie nt locally (on th e I833 0 device).

connection is possible only if another device (e.g., a router) to which the I8330 is
connected includes a VPN client and can, therefore, make the VPN connection.

A VPN

I94xx I/Ports

To ensure 100/full-duplex throughput between a V51xx card in a blade and an I94xx I/Port, set
any network switches connecting the blade and the I/Port to automatic negotiation. Explicitly
setting a network switch to 100/full-duplex can cause throughput issues. If there are
performance or throughput issues after setting network switches to automatic negotiation,
physically disconnect and then reconnect the network cables to the switch.

Appendix B. Troubleshooting

This appendix provides troubleshooting information for the I9420 I/Port.

The I9420 I/Port is connected to a 100/full-duplex switch but performance is
poor and throughput is not full-duplex.

To ensure 100/full-duplex throughput between a V5120 card in a blade and an I9420 I/Port, set
any network switches connecting the blade and the I/Port to automatic negotiation. Explicitly
setting a network switch to 100/full-duplex can cause throughput issues. If there are
performance or throughput issues after setting network switches to automatic negotiation,
physically disconnect and then reconnect the network cables to the switch.

The I9420 I/Port does not connect to a blade when I disable DHCP or change the
IP address of the I/Port’s V5120 Dual Hostcard.

The I9420 and the V5120 Dual Host card that it contains have DHCP connection mode
enabled by default. If a DHCP address is not granted within 20 seconds of starting the I/Port,
each device defaults to the following static IP addresses:

• I9420—192.168.1.100

• V5120—192.168.1.101

Each device has a Web page interface that you can use to:

• Enable and disable DHCP connection mode.

• Specify static IP addresses for the subnet and default gateway.

If you disable the I/Port's DHCP setting, the I/Port cannot connect to a blade if the I/Port's
static IP address and default gateway are on different subnets.

Resolution

If the devices are on a know subnet, you can discover a specific device to display the device's
IP and MAC address.

To prevent this issue:

• Avoid disabling the I/Port's DHCP setting.

• If you specify a static IP address for the V5120, ensure that you record it.

• Ensure that the I/Port's IP address and default gateway are on the same subnet.

My I9420 I/Port does not recognize my keyboard, my mouse, or both. When I
start the I/Port the Add New Hardware wizard starts and I cannot dismiss the
wizard.

The Realtek® HDAudio driver must be installed on a blade to use the I9420 or C7420. If the
driver is not installed it can cause the Add New Hardware Wizard to start before the USB
driver is installed. In this case there is no keyboard or mouse support and you cannot dismiss
the wizard.

Resolution

Include the Realtek HDAudio driver in any image that you install on your blade.

If you encounter this scenario:

• Connect a PS/2 keyboard or mouse to the USB port on the blade to dismiss the wizard.

• Install an image with the HDAudio driver on the blade.

When I connect one monitor to video port 1 of an I9420 I/Port or a C7420 C/Port
in direct connect mode, video is not displayed after I configure the I/Port.

If you connect a single monitor to video port 1 of an I9420 I/Port or a C7420 C/Port, and the
I/Port is connected to a blade with the G0530005 XP SP2 factory image, video is not displayed
through port 1 after you configure the I/Port.

Resolution

After configuring the I/Port, connect the monitor to port 2. Video is displayed through video
port 2 after a connection is established.

I cannot use the remote power button to start a blade or shut down a blade.

Remote Power Button

The remote power button is located on the right side of the rear of the blade. The I9420 remote
power button does not start or shut down the blade, or when I try to connect to a blade I
receive a System Busy! message.

Resolution

Ensure that there are not any V5120, I9420, or C7420 configuration Web pages open when
you use the remote power button to start, power cycle, or shut down a I9420 I/Port. If V5120
configuration Web pages are open when you press the remote power button, they can interfere
with the session between the blade and I9420 and produce unsupported behavior.

The A1410 blade does not support standby state. Briefly press the remote power (less than
four seconds) to perform a graceful shutdown, or soft power off.

I9420 does not support the hard reset option, or Hard-Power off (pressing and holding the
remote client power button for more than four seconds). In the V5120 configuration Web
page, click Permissions and then click Power. Ensure that Soft-Power off is selected. No
other option is supported.

The I9420 displays an

Peer MAC Address

After configuring the I9420, the I/Port displays error messages about MAC addresses.

Error: Value must be 0-FF or an Invalid

error message.

Resolution

You have changed the Connection Type to RDP, which is unsupported. From the V5120
configuration Web page, click Permissions and then click Sessions. Select PcoIP in the
Session Type drop-down menu.

The mass storage lockout (MSL) jumper in the blade does not prevent mass
storage devices from operating on the I9420.

The MSL feature is not implemented in December 2007 release.

Resolution

Use the Permissions tab on the I9420 and C7420 to enable MSL. From the V5120
configuration Web page, click Permissions and then click USB.

The default I/Port behavior is to permit all USB mass storage devices. You can add mass
storage devices to a list of prohibited devices can be added by class, vendor, or specific ID.
You can specify a password to access these screens.

If mass storage lockout (MSL) is enabled on a I9420 or C7420 I/Port in a Sentral
environment and I insert a USB device in the I/Port, an empty, gray dialog box is
displayed.

You can enable mass storage lockout through a blade's V5120 configuration Web page. When
you insert a USB device in the I/Port and the I/Port is in a direct connect mode, a gray dialog
box is displayed that says USB device is not authorized.

If the I/Port is in a Sentral environment and MSL is enabled, the dialog box displayed when
you insert a USB device does not contain any text.

Resolution

Remove the USB device to dismiss the dialog box.

I cannot connect a I/Port to a blade using RDP, or I receive an Alert:

Session timeout!

I9420 I/Ports use PCoIP technology to deliver video, USB, and audio data. These user ports do
not currently support RDP.

message.

Resolution

From the I/Port V5120 configuration Web page, click Configuration > Session and ensure
that you select PCoIP in the Session Type drop-down menu.
