Introducing the HP Jetdirect Network Projector Manager
Introduction
The HP Jetdirect network projector manager is a server that connects a
projector directly to a network, so that you can manage it from anywhere on
the network.
Throughout this manual, this product is called a projector server.
Security Protocols
SNMP
SNMP (Simple Network Management Protocol) is used by network
management applications for device management. HP Jetdirect projector
servers support SNMP and standard MIB-II (Management Information Base)
objects on IP networks.
HP Jetdirect projector servers support an SNMP v1/v2c agent, and an
SNMP v3 agent for enhanced security.
HTTPS
HP Jetdirect projector servers support HTTPS (Secure Hyper Text Transfer
Protocol) for secure, encrypted management communications between their
embedded Web servers and your Web browser.
ENWW 5
Authentication
EAP/802.1X Server-Based Authentication
As a network client, the HP Jetdirect projector server support network access
using the Extensible Authentication Protocol (EAP) on an IEEE 802.1X
network. The IEEE 802.1X standard provides a port-based authentication
protocol where a port can allow or block access depending on client
authentication results.
When using an 802.1X connection, the projector server supports Extensible
Authentication Protocol (EAP) with an authentication server, such as a
RADIUS (Remote Authentication Dial In User Service, RFC 2138) server.
Projector servers support the following EAP/802.1X method:
● PEAP (Protected Extensible Authentication Protocol). PEAP is a mutual
authentication protocol that uses digital certificates for network server
authentication and passwords for client authentication. For additional
security, the authentication exchanges are encapsulated within TLS
(Transport Layer Security). Dynamic encryption keys are used for secure
communications.
The network infrastructure device that connects the projector server to the
network (such as an HP Procurve switch) must also support the EAP/802.1X
method used. In conjunction with the authentication server, the infrastructure
device can control the degree of network access and services available to the
server client.
To configure the server for EAP/802.1X authentication, you must access the
embedded Web server through your Web browser. For more information, see

TCP/IP Configuration
Introduction
To operate properly on a TCP/IP network, the HP Jetdirect projector server
must be configured with valid TCP/IP network configuration parameters, such
as an IP address that is valid for your network. For general information on
TCP/IP networks, see Appendix A
Server-Based and Manual TCP/IP Configuration
When in a factory-default state and powered on, the HP Jetdirect projector
server will try to obtain its TCP/IP configuration using a server-based method,
such as BOOTP/TFTP, DHCP/TFTP, or RARP. These server-based methods
are described later in this chapter. Depending on the server model, up to two
minutes may be used for these methods. If configuration is not successful, a
default IP address will be assigned.
The server may also be configured manually. Manual-based tools include a
Web browser, arp and ping commands (when the default IP address is
192.0.0.192), or SNMP-based management software. TCP/IP configuration
values assigned manually will be retained when powered off/on.
.
The server can be reconfigured to use either server-based or manual
configuration of TCP/IP settings at any time.
To identify the IP address that is configured on the projector server at any
time, see the IP address displayed in the projector’s on-screen Help menu.
ENWW 12
Default IP Address
When in a factory-default state (for example, when shipped from the factory
or after a cold-reset), the HP Jetdirect projector server has no IP address. A
default IP address may or may not be assigned depending on the network
environment.
Default IP Address Will Not Be Assigned
A default IP address will not be assigned if a server-based method (such as
BOOTP or DHCP) is successful. And if the server is powered off/on, the same
method will again be used to retrieve IP configuration settings. If this method
now fails to retrieve the IP configuration settings (for example, the BOOTP
or DHCP server is no longer available), a default IP address will not be
assigned. Instead, the server will continue to send IP configuration requests
indefinitely. You must cold-reset the server to change this behavior.
In addition, a default IP address will not be assigned if a network cable is not
attached.
Default IP Address Will Be Assigned
A default IP address will be assigned if the factory-default methods fail, or if
the server has just been reconfigured by an administrator to use a server-based
method (such as BOOTP or DHCP) that fails.
If a default IP address is assigned, the address will depend on the network to
which the server is connected. The server senses broadcast packets on the
network to determine the appropriate default IP settings:
● On small private networks that adhere to automated, standards-based IP
address assignments, the server uses a link-local addressing technique to
assign a unique IP address. Link-local addressing is limited to a local IP
subnet (not routed) and may be referenced as Au to IP. The IP address
assigned will be in the range of 169.254.1.0 to 169.254.254.255
(commonly referenced as 169.254/16). However, it can be further
modified for your network using supported TCP/IP configuration tools if
necessary.
With link-local addresses, subnetting is not used. The subnet mask will
be 255.255.0.0, and cannot be changed.
ENWW TCP/IP Configuration 13
Link-local addresses will not route off the local link, and access to or from
the Internet will not be available. The default gateway address will be the
same as the link-local address.
If a duplicate address is sensed, the HP Jetdirect server will automatically
reassign its address, if necessary, in accordance with standard link-local
addressing methods.
● On large or enterprise IP networks, a temporary address of 192.0.0.192
will be assigned until it is reconfigured with a valid address through
supported TCP/IP configuration tools. We refer to this address as Legacy
Default IP.
● On mixed-environment networks, the self-assigned default IP address
may be either 169.254/16 or 192.0.0.192. In this case, you should verify
through the projector’s on-screen Help menu that the assigned default IP
address is as expected.
The IP address configured on your projector server can be found on the
projector’s on-screen Help menu.
Default IP Address Configuration Options
Default IP Parameter
A Default IP configuration parameter on the projector server controls how the
default IP address is assigned. Whenever the server is unable to obtain an IP
address during a forced TCP/IP reconfiguration (for example, when manually
configured to use BOOTP or DHCP), this parameter will determine the default
IP address to use.
When the server is in a factory-default state, this parameter is undefined.
If the server is initially configured with a default IP address (either a link-local
IP address or the legacy default 192.0.0.192 IP address), the Default IP
parameter will be set to either Auto IP or Legacy Default IP to match.
The Default IP parameter can be changed through a supported configuration
tool, such as a Web browser and SNMP management applications.
ENWW TCP/IP Configuration 14
DHCP Requests Enable/Disable
When a default IP address is assigned, you can configure the projector server
to send, or not send, periodic DHCP requests. DHCP requests are used to
retrieve IP configuration settings from a DHCP server on the network. By
default, this parameter is enabled, allowing DHCP requests to be transmitted.
However, this parameter may be disabled through supported configuration
tools such as a Web browser, and SNMP management applications.
TCP/IP Configuration Tools
When a network connection has been established, an HP Jetdirect projector
server can be configured with valid TCP/IP parameters for your network in
the following ways:
● Using Software. You can use installation, setup, and management
software running on supported systems. For more information see
Chapter 2
● BOOTP/TFTP. You can download the data from a network-based server
using BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer
Protocol) each time the projector is turned on. For more information, see
“U

is accessible by the projector.
, “HP Web Jetadmin”.
sing BOOTP/TFTP”.
● DHCP/TFTP. You can use Dynamic Host Configuration Protocol
(DHCP) and TFTP (Trivial File Transfer Protocol) each time the projector
is turned on. These protocols are supported on HP-UX, Solaris, Linux,
Windows NT/2000/Server 2003, NetWare and Mac OS systems. (Refer
to your network operating system manuals to verify that your server
operating system supports DHCP.) For more information, see “Using
DHCP”.
ENWW TCP/IP Configuration 15
Note Linux and UNIX systems: For more information, see the
bootpd “man” page.
On HP-UX systems, a sample DHCP configuration file
(dhcptab) may be located in the /etc directory.
Since HP-UX presently does not provide Dynamic Domain
Name Services (DDNS) for its DHCP implementations,
HP recommends that you set all projector server lease
durations to infinite. This ensures that server IP addresses
remain static until such time as Dynamic Domain Name
Services are provided.
● RARP. A network-based server can use RARP (Reverse Address
Resolution Protocol) to answer the projector server’s RARP request and
supplying the server with the IP address. The RARP method only allows
you to configure the IP address. For more information, see “U

default IP address 192.0.0.192 only) You can use the arp and ping
commands from your system. For more information, see “Using the arp
and ping Commands.”
● Embedded Web server. You can browse to the embedded Web server
on the HP Jetdirect projector server to set configuration parameters. For
more information, see Chapter 4
.
ENWW TCP/IP Configuration 16
Using BOOTP/TFTP
BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol)
provide a convenient way to automatically configure the HP Jetdirect
projector server for TCP/IP network operation. When powered on, the
Jetdirect server sends a BOOTP request message onto the network. A properly
configured BOOTP server on the network will respond with a message that
contains basic network configuration data for the Jetdirect server. The BOOTP
server’s response may also identify a file that contains extended configuration
data for the server. The Jetdirect server downloads this file using TFTP. This
TFTP configuration file may be located on the BOOTP server, or a separate
TFTP server.
BOOTP/TFTP servers are typically UNIX or Linux systems. Windows
NT/2000/Server 2003 and NetWare servers can respond to BOOTP requests.
Windows NT/2000/Server 2003 servers are configured through Microsoft
DHCP services (see “Using DHC
2003 systems may require third-party software for TFTP support. For setup
of NetWare BOOTP servers, refer to your NetWare documentation.
Note If the Jetdirect projector server and BOOTP/DHCP server
are located on different subnets, IP configuration may fail
unless the routing device supports “BOOTP Relay” (allows
the transfer of BOOTP requests between subnets).
P”). However, Windows NT/2000/Server
Why Use BOOTP/TFTP?
Using BOOTP/TFTP to download configuration data has the following
benefits:
● Enhanced configuration control of the HP Jetdirect projector server.
Configuration by other methods are limited to select parameters.
● Ease of configuration management. Network configuration parameters for
the entire network can be in one location.
● Ease of HP Jetdirect projector server configuration. Complete network
configuration can be automatically downloaded each time the server is
powered on.
ENWW TCP/IP Configuration 17
Note BOOTP operation is similar to DHCP, but the resulting IP
parameters will be the same when powered off/on. In
DHCP, IP configuration parameters are leased and may
change over time.
When in its factory-default state and powered on, the HP Jetdirect projector
server will attempt to automatically configure itself using several dynamic
methods, one of which is BOOTP.
BOOTP/TFTP on UNIX
This section describes how to configure the projector server using BOOTP
(Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) services on
UNIX servers. BOOTP and TFTP are used to download network
configuration data from a server to the HP Jetdirect projector server over the
network.
Systems That Use Network Information Service (NIS)
If your system uses NIS, you may need to rebuild the NIS map with the
BOOTP service before performing the BOOTP configuration steps. Refer to
your system documentation.
Configuring the BOOTP Server
For the HP Jetdirect projector server to obtain its configuration data over the
network, the BOOTP/TFTP servers must be set up with the appropriate
configuration files. BOOTP is used by the projector server to obtain entries
in the /etc/bootptab file on a BOOTP server, while TFTP is used to
obtain additional configuration information from a configuration file on a
TFTP server.
When the HP Jetdirect projector server is powered on, it broadcasts a BOOTP
request that contains its MAC (hardware) address. A BOOTP server daemon
searches the /etc/bootptab file for a matching MAC address, and if
successful, sends the corresponding configuration data to the Jetdirect
projector server as a BOOTP reply. The configuration data in the
/etc/bootptab file must be properly entered. For a description of entries,
see “Bootptab File Entries
ENWW TCP/IP Configuration 18
.”
The BOOTP reply may contain the name of a configuration file containing
enhanced configuration parameters. If the HP Jetdirect projector server finds
such a file, it will use TFTP to download the file and configure itself with
these parameters. For a description of entries, see “TFTP Configuration File
Entries.” Configuration parameters retrieved through TFTP are optional.
Note HP recommends that the BOOTP server be located on the
same subnet as the projectors it serves. BOOTP broadcast
packets may not be forwarded by routers unless the
routers are properly configured.

traps. Authentication traps indicate that an SNMP request was received, but the
community name check failed. The default is “on.”
trap-dest:
(trap-destination:)
Enters a host’s IP address into the HP Jetdirect projector server’s SNMP trap
destination list. The command format is:
trap-dest: ip-address [community name] [port number]
The default community name is “public”; the default SNMP port number is “162”.
The port number cannot be specified without a community name.
If a “trap-community-name” command is followed by “trap-dest” commands, the
trap community name will be assigned to those entries unless a different
community name is specified in each “trap-dest” command.
To delete the table, use “trap-dest: 0”.
If the list is empty, the server does not send SNMP traps. The list may contain up
to three entries. The default SNMP Trap Destination List is empty. To receive
SNMP traps, the systems listed on the SNMP trap destination list must have a trap
daemon to listen to those traps.

ENWW TCP/IP Configuration 31
Using DHCP
Dynamic Host Configuration Protocol (DHCP, RFC 2131/2132) is one of
several auto configuration mechanisms that the HP Jetdirect projector server
uses. If you have a DHCP server on your network, the HP Jetdirect projector
server automatically obtains its IP address from that server and registers its
name with any RFC 1001 and 1002-compliant dynamic name services as long
as a WINS (Windows Internet Naming Service) server IP address has been
specified.
A TFTP (Trivial File Transfer Protocol) configu r ation file may also be used
with DHCP to configure extended parameters. For more information on TFTP
parameters, see “U
Note DHCP services must be available on the server. Refer to
Note If the Jetdirect projector server and BOOTP/DHCP server
sing BOOTP/TFTP.”

enable DHCP services.
are located on different subnets, IP configuration may fail
unless the routing device allows the transfer of DHCP
requests between subnets.
ENWW TCP/IP Configuration 32
UNIX Systems
For more information on setting up DHCP on UNIX systems, see the bootpd
man page.
On HP-UX systems, a sample DHCP configuration file (dhcptab) may be
located in the /etc directory.
Since HP-UX presently does not provide Dynamic Domain Name Services
(DDNS) for its DHCP implementations, HP recommends that you set all
projector server lease durations to “infinite”. This ensures that server IP
addresses remain static until dynamic domain name services are provided.
Windows Systems
HP Jetdirect projector servers support IP configuration from a supported
Windows DHCP server. This section describes how to set up a pool, or
“scope,” of IP addresses that the Windows server can assign or lease to any
requester. When configured for BOOTP or DHCP operation and powered on,
the HP Jetdirect projector server automatically sends a BOOTP or DHCP
request for its IP configuration. If properly set up, a Windows DHCP server
will respond with the projector server’s IP configuration data.
Note This information is provided as an overview. For specific
information or for additional support, see the information
supplied with your DHCP server software.
Note To avoid problems resulting from IP addresses that change,
HP recommends that all projectors be assigned IP addresses
with infinite leases or reserved IP addresses.
ENWW TCP/IP Configuration 33
Windows NT 4.0 Server
To set up a DHCP scope on a Windows NT 4.0 server, perform the following
steps:
1. At the Windows NT server, open the Program Manager window and
double-click the Network Administrator icon.
2. Double-click the DHCP Manager icon to open this window.
3. Select Server and select Server Add.
4. Type the server IP address, then click OK to return to the DHCP Manager
window.
5. In the list of DHCP servers, click on the server you have just added, then
select Scope and select Create.
6. Select Set up the IP Address Pool. In the IP Address Pool section, set
up the IP address range by typing the beginning IP address in the Start
Address box and the ending IP address in the End Address box. Also type
the subnet mask for the subnet to which the IP address pool applies.
The starting and ending IP addresses define the end points of the address
pool assigned to this scope.
Note If desired, you can exclude ranges of IP addresses within a
scope.
7. In the Lease Duration section, select Unlimited, then select OK.
HP recommends that all projectors be assigned infinite leases to avoid
problems resulting from IP addresses that change. Be aware, however,
that selecting an unlimited lease duration for the scope causes all clients
in that scope to have infinite leases.
If you want clients on your network to have finite leases, you can set the
duration to a finite time, but you should configure all projectors as
reserved clients for the scope.
ENWW TCP/IP Configuration 34
8. Skip this step if you have assigned unlimited leases in the previous step.
Otherwise, select Scope and select Add Reservations to set up your
projectors as reserved clients. For each projector, perform the following
steps in the Add Reserved Clients window to set up a reservation for that
projector:
a. Type the selected IP address.
b. Obtain the MAC address or hardware address from the label on the
server, embedded web server, or on-screen Help menu, and type this
address in the Unique Identifier box.
c. Type the client name (any name is acceptable).
d. Select Add to add the reserved client. To delete a reservation, in the
DHCP Manager window, select Scope and select Active Leases.
In the Active Leases window, click on the reservation you want to
delete and select Delete.
9. Select Close to return to the DHCP Manager window.
10. Skip this step if you are not planning to use WINS (Windows Internet

a. From the DHCP Manager window, select DHCP Options and
select one of the following:
Scope — if you want Name Services only for the selected scope.
Global — if you want Name Services for all scopes.
b. Add the server to the Active Options list. From the DHCP Options
window, select WINS/NBNS Servers (044) from the Unused
Options list. Select Add, then select OK.
A warning may appear requesting that you set the node type. You
do this in step 10d.
ENWW TCP/IP Configuration 35
c. You must now provide the IP address of the WINS server by doing
the following:
● Select Value, then Edit Array.
● From the IP Address Array Editor, select Remove to delete any
undesired addresses previously set. Then type in the IP address
of the WINS server and select Add.
● Once the address appears in the list of IP addresses, select OK.
This returns you to the DHCP Options window. If the address
you have just added appears in the list of IP addresses (near the
bottom of the window) return to step 10d. Otherwise, repeat step
10c.
d. In the DHCP Options window, select WINS/NBT Node Type
(046) from the Unused Options list. Select Add to add the node
type to the Active Options list. In the Byte box, type 0x4 to indicate
a mixed node, and select OK.
11. Click Close to exit to Program Manager.

c. Enter the appropriate information in each field, including the
reserved IP address for your projector. (Note: the MAC address for
your HP Jetdirect-connected projector is available on the label on
the server, embedded web server, or on-screen Help menu.)
d. Under “Supported types”, select DHCP only, then click Add.
(Note: Selecting Both or BOOTP only will result in a configuration
through BOOTP due to the sequence in which HP Jetdirect projector
servers initiate configuration protocol requests.)
e. Specify another reserved client, or click Close. The reserved clients
added will be displayed in the Reservations folder for this scope.
12. Close the DHCP manager utility.
To Discontinue DHCP Configuration
CAUTION Changes to an IP address on your HP Jetdirect projector
server may require updates to device or system
configurations for clients or servers.
If you do not want your HP Jetdirect projector server configured through
DHCP, you must reconfigure the server to use a different configuration
method.
● You can manually modify the TCP/IP parameters through a supported
Web browser using the Jetdirect embedded Web server or HP Web
Jetadmin.
If you change to BOOTP configuration, the DHCP-configured parameters are
released and the TCP/IP protocol is initialized.
ENWW TCP/IP Configuration 38
If you change to Manual configuration, the DHCP-configured IP address is
released and the user-specified IP parameters are used. Therefore, if you
manually provide the IP address, you should also manually set all of the
configuration parameters, such as subnet mask, default gateway, and
idle timeout.
Note If you choose to re-enable a DHCP configuration, the
projector server will acquire its configuration information
from a DHCP server. This means that when you choose
DHCP and complete your configuration session, the TCP/IP
protocol for the projector server is re-initialized and all
current configuration information is deleted. The projector
server then attempts to acquire new configuration
information by sending DHCP requests on the network to a
DHCP server.
ENWW TCP/IP Configuration 39
Using RARP
This section describes how to configure the projector server using the Reverse
Address Resolution Protocol (RARP) on UNIX and Linux systems.
This setup procedure enables the RARP daemon running on your system to
respond to a RARP request from the HP Jetdirect projector server and to
supply the IP address to the server.
1. Turn the projector off.
2. Log onto your UNIX or Linux system as a superuser.
3. Make sure the RA RP daem on is running on your system by typing the
following command at the system prompt:
ps -ef | grep rarpd (Unix)
ps ax | grep rarpd (BSD or Linux)
4. The system response should be simil ar to the following:
861 0.00.2 24 72 5 14:03 0:00 rarpd -a
860 0.00.5 36 140 5 14:03 0:00 rarpd -a
5. If the system does not display a process number for the RARP daemon,
see the rarpd man page for instructions on starting the RARP daemon.
6. Edit the /etc/hosts file to add your designated IP address and node
name for the HP Jetdirect projector server. For example:
192.168.45.39 projector1
7. Edit the /etc/ethers file (/etc/rarpd.conf file in
HP-UX 10.20) to add the LAN hardware address/station address (from
the label on the server, embedded web server, or on-screen Help menu)
and the node name for the HP Jetdirect projector server. For example:
00:01:E6:a8:b0:00 projector1
ENWW TCP/IP Configuration 40
Note If your system uses Network Information Service (NIS),
you need to incorporate changes to the NIS host and ethers
databases.
8. Turn the projector on.
9. To verify that the card is configured with the correct IP address, use the
ping utility. At the prompt, type:
ping <IP address>
where <IP address> is the assigned address from RARP.
10. If ping does not respond, see Chapter 6
.
ENWW TCP/IP Configuration 41
Using the arp and ping Commands
You can configure an HP Jetdirect projector server with an IP address using
an ARP (Address Resolution Protocol) command from a supported system.
The protocol is not routable, that is, the workstation from which the
configuration is made must be located on the same network segment as the
HP Jetdirect projector server.
Using the arp and ping commands with HP Jetdirect projector servers requires
the following:
● Windows NT/2000/XP/Server 2003 or UNIX system configured for
TCP/IP operation
● A legacy default IP address 192.0.0.192 has been set on the projector
server
● The LAN hardware (MAC) address of the HP Jetdirect projector server
(specified on the label on the server, embedded web server, or on-screen
Help menu)
Note On some systems, superuser rights may be required for the
arp command.
After an IP address is assigned through arp and ping commands, use other
tools (such as embedded Web server or HP Web Jetadmin software) to
configure other IP parameters.
To configure a Jetdirect projector server, use the following commands:
arp -s <IP address> <LAN hardware address>
ping <IP address>
where <IP address> is the desired IP address to be assigned to the
projector server. The arp command writes the entries to the arp cache on the
workstation, and the ping command configures the IP address on the server.
ENWW TCP/IP Configuration 42
Depending on the system, the LAN hardware address may require a specific
format.
For example:
● For Windows NT 4.0, 2000, XP, Server 2003
arp -s 192.168.45.39 00-01-E6-a2-31-98
ping 192.168.45.39
● For UNIX
arp -s 192.168.45.39 00:01:E6:a2:31:98
ping 192.168.45.39
Note Once the IP address has been set on the projector server,
additional arp and ping commands will be ignored. Once
the IP address is configured, arp and ping cannot be used
unless the server is reset to factory values (see Chapter6
On UNIX systems, the arp -s command may vary
between different systems.
Some BSD-based systems expect the IP address (or host
name) in reverse order. Other systems may require
additional parameters. See your system documentation for
specific command formats.
).
ENWW TCP/IP Configuration 43
Using the Embedded Web Server
You can set IP parameters on HP Jetdirect projector servers that support the
embedded Web server. For more information, refer to Chapter 4
.
Moving to Another Network
When moving an HP Jetdirect projector server that is configured with an IP
address to a new network, make sure that the IP address does not conflict with
addresses on the new network. You may change the IP address of the server
to one that can be used on the new network, or erase the current IP address
and configure another address after it is installed on the new network. See
Chapter 6
instructions to reset the server to factory default settings.
If the current BOOTP server is not reachable, you may need to locate a
different BOOTP server and configure the projector to this server.
If the server was configured using BOOTP, DHCP or RARP, edit the
appropriate system files with updated settings. If the IP address was manually
set, reconfigure IP parameters as described in this chapter.

Viewing the Embedded Web Server
Before you can use the embedded Web server, the HP Jetdirect projector
server must be configured with an IP address. For a description of an IP address
and an overview of TCP/IP networking, see Appendix A
There are many ways to configure an IP address on the server. For example,
you can automatically configure IP parameters over the network using
BOOTP (Bootstrap Protocol) or DHCP (Dynamic Host Configuration
Protocol) each time the server is turned on. Or, you can manually configure
IP parameters using the “arp” and “ping” commands, HP Web Jetadmin, or
other management software. For more information on TCP/IP configuration
options, see Chapter 3
When powered on, an HP Jetdirect server that is unable to retrieve a valid IP
address from the network will automatically assign itself either a legacy
default IP address 192.0.0.192 or a link-local address in the range 169.254.1.0
to 169.254.254.255. The IP address configured on your server can be
determined by inspecting the IP address shown in the projector’s on-screen
menus. See Chapter 3
If the legacy default IP address 192.0.0.192 has been assigned, you must
temporarily set up your computer with the same IP network number or
establish a route to the server before you can gain access to the embedded Web
server.
To access the embedded Web server, perform the following steps:

3. If prompted with security alerts, click Yes to proceed.
For initial access, the embedded Web server uses standard HTTP.
However, it can be configured to appear as a secure site, using an
X.509-compliant certificate installed on the projector server for
identification. When properly configured, encrypted browser
communications through HTTPS (secure HTTP) may be used for secure
access.
Although not recommended, you can use your Internet Options menu to
configure your browser to ignore security warnings if the projector server
is configured to operate through HTTPS. See “Mgmt. Protocols

Certificates
This tab provides access to installation, configuration and management
services for X.509 digital certificates. A digital certificate is an electronic
message typically containing, among other things, a key (a short string used
for encryption and decryption) and a digital signature. Certificates may be
issued and signed by a trusted third party (commonly called a Certificate
Authority, or CA), which may exist internal or external to the organization.
Or certificates may be “self-signed”, which is similar to validating your own
identity.
Note While self-signed certificates are permitted and allow data
encryption, they do not ensure valid authentication.
The Certificates page provides the status of the certificates installed on the
HP Jetdirect projector server:
● Jetdirect certificate. The Jetdirect certificate is used to validate the
identity of the Jetdirect device to clients and to network authentication
servers.
By factory default, a self-signed Jetdirect certificate is preinstalled. This
allows the embedded Web server to use HTTPS and appear as a secure site
when accessed by a Web browser.
Click View to view the contents of an installed Jetdirect certificate, or click
Configure to update or install a new one. See “Configuring Certificates
.”
When installed, a Jetdirect certificate will be saved across a cold-reset,
which is used to restore the projector server to factory-default values.
● CA Certificate. A certificate from a trusted third party, or Certificate
Authority (CA), is used to validate the identity of a network authentication
server during 802.1X authentication methods that use EAP (Extensible
Authentication Protocol). The authentication server’s identity is validated
when information on the CA certificate matches the information on a
certificate received from the authentication server.
A CA certificate for the projector server is a certificate that was used to
sign the authentication server’s certificate. Therefore, the Certificate
Authority for the authentication server’s certificate must also be used for
the CA certificate.
ENWW Using the Embedded Web Server 65
Click View to view the contents of an installed Jetdirect certificate, or click
Configure to update or install a new one. See “Configuring Certificates

The maximum certificate size that can be installed on the HP Jetdirect
projector server is 3072 bytes.
Configuring Certificates
When you click Configure, a certificate management wizard will help you
update or install a certificate. The screens displayed will depend on the type
of certificate (Jetdirect or CA) and your selections. Table 4.7
provides a
description of the screens and configuration parameters that may appear.
Note If you improperly exit Certificates configuration (for
example, by failing to use the Cancel button), an Operation
Failed screen may appear. If so, wait approximately two
minutes before entering the wizard again.

Certificate Options
Choose from the options listed.
Update Pre-Installed Certificate. Use this option to update the preinstalled,
self-signed certificate. When updated, the preinstalled certificate is
overwritten.You may update the following item:
● Certificate Validity Period
With self-signed certificates, the browser will identify the certificate as self-signed
for each new Web session and may cause a security alert message. This
message can be bypassed if the user adds it to their browser’s certificate store
or disables browser alerts (not recommended).
Self-signed certificates are not necessarily secure because the certificate owner
is merely confirming his own identity instead of verification by a trusted third party.
Certificates from a trusted third party are considered more secure.

Access Control
Use this tab to display the Access Control List (ACL) on the HP Jetdirect
projector server. An access control list (or host access list) specifies individual
host systems, or networks of host systems, that will be allowed to access the
server and the attached network device. Up to 10 entries can be included on
the list. If the list is empty (no hosts are listed), any supported system can
access the server.
CAUTION Use caution when using this feature. You may lose your
ability to communicate with the HP Jetdirect projector
server if your system is not properly specified in the list, or
access through HTTP is disabled.
For use of the host access list as a security feature, see
Chapter 5
.
Note By default, hosts with HTTP connections (for example,
through the embedded Web server) are allowed access to
the projector server regardless of access control list entries.
To disable access by HTTP hosts, clear the Allow Web
Server (HTTP) access checkbox at the bottom of the list.
Host systems are specified by their IP addresses or network number. If the
network contains subnets, an address mask may be used to identify whether
the IP address designates an individual host system or a group of host systems.
Examples. See the table of sample entries below:
IP Address Mask Description
192.0.0.0 255.0.0.0 Allow all hosts with network number 192.
192.1.0.0 255.1.0.0 Allow all hosts on network 192, subnet 1.
192.168.1.2 Allow the host with IP address 192.168.1.2.
The mask 255.255.255.255 is assumed and is
not required.
ENWW Using the Embedded Web Server 70
To add an entry into the access control list, use the IP Address and Mask
fields to specify a host, and click (check) the Save checkbox for that entry.
Then click Apply.
To delete an entry from the list, clear the Save checkbox for that entry. Then
click Apply.
To clear the entire access control list, clear all Save checkboxes, and click
Apply.
Mgmt. Protocols
This link provides access to management communications and other protocols
that affect security.
Web Mgmt.
Use this tab to manage communications with the embedded Web server from
Web browsers.
Secure, encrypted Web-based communication is provided through the Secure
HTTP (HTTPS) protocol. If configured to require HTTPS, the embedded Web
server routes HTTPS communications through port 443, the well-known port
for HTTPS traffic. Other non-secure communications (HTTP) are redirected
to HTTPS. Redirection of your browser to use HTTPS may be transparent
depending on your browser’s capabilities.
By factory default, the projector server is configured to allow HTTPS or
HTTP.
Although not recommended, you may choose to accept both HTTPS and
HTTP communications that are not secure by disabling (clearing) the Encrypt
All Web Communication checkbox.
To support the use of HTTPS communications, a Jetdirect certificate must be
installed. A factory-default, self-signed certificate is preinstalled for initial
use. Click the Configure button to update the preinstalled certificate, or to
install a new one. For more information, see “Configuring Certificates
.”
The minimum encryption strength that will be allowed must be specified when
using a Jetdirect certificate. You may select Low (default), Medium, or High
encryption strength. For example, selecting Low will allow medium or high
encryption levels to be used whereas selecting High will onl y allow high
encryption levels.
For each encryption strength, ciphers are specified to identify the weakest
cipher allowed. Early browsers may only support 40-bit (Low) encryption
levels.
ENWW Using the Embedded Web Server 71
Note Cipher suites support different levels of encryption strength.
The cipher suites currently supported for encryption and
decryption are DES (Data Encryption Standard, 56-bit),
RC4 (40-bit or 128-bit), and 3DES (168-bit).
SNMP
Use this tab to enable or disable SNMP v1, v2c and v3 agents on the server.
For a description of SNMP selections, see Table 4.4
.
SNMP v3. HP Jetdirect projector servers include an SNMP v3 (Simple
Network Management Protocol, version 3) agent, for enhanced SNMP
security. The SNMP v3 agent employs a User-based Security Model for
SNMP v3 (RFC 2574), which features user-authentication and data privacy
through encryption.
The SNMP v3 agent is enabled when an initial SNMP v3 account on the server
is created. Once the account is created, any SNMP management application,
if properly configured, can access or disable the account.
CAUTION If you use HP Web Jetadmin to manage your devices, you
should use HP Web Jetadmin to seamlessly configure
SNMP v3 and other security settings on the projector server.
Using the embedded Web server to create the SNMP v3
account will erase any existing SNMP v3 accounts. In
addition, the SNMP v3 account information will need to be
implemented on the SNMP management application.
You may create the initial account by specifying the HMAC-MD5
authentication and CBC-DES data privacy encryption keys used by your
SNMP v3 management application.
ENWW Using the Embedded Web Server 72
CAUTION You should ensure secure embedded Web communications
through HTTPS is enabled before creating the initial SNMP
v3 account. This will help to prevent access or interception
of account information over a connection that is not secure.
SNMP v1 and v2c agents can coexist with the SNMP v3
agent. However, to fully secure SNMP access, you should
disable SNMP v1 and v2c.

802.1x Authentication
This page allows you to configure 802.1X authentication settings on the
Jetdirect projector server as required for client authentication on your network.
In addition, you can reset the 802.1X authentication settings to factory-default
values.
CAUTION Use caution when changing the 802.1X authentication
settings; you may lose your connection. If communication
with the projector is lost, you may need to reset the projector
server to a factory-default state and then reinstall the device.
For most 802.1X networks, the infrastructure components (such as LAN
switches) must use 802.1X protocols to control a port’s access to the network.
If these ports do not allow partial or guest access, the projector server may
need to be configured with your 802.1X parameters prior to connection.
To configure initial 802.1X settings before connecting to your network, you
can use an isolated LAN, or a direct computer connection using a cross-over
cable.
The supported 802.1X authentication protocols and associated configuration
depend on the server model and firmware version. Available configuration
settings are listed in Table 4.9
.

Resolving Problems with the Indicator Lights
Check the following items to see whether the projector server is operating
properly.
1. Power/status light:
◆ If the light is flickering green, network activity is normal. No problem
indicated.
◆ If the light is off, power is not connected. Check the power module
and power source.
◆ If the light is on steady, there is no network activity. Go to “Resolving
Communication Problems with the Network,” below.
◆ If the light slowly blinks green more than 15 seconds after startup,
no network is detected. Go to “R
with the Network,” below.
◆ If the light blinks orange, disconnect and reconnect power at the
Jetdirect server. If the condition persists, the server is faulty.
2. USB/projector light :
◆ If the light is on steady, the USB connection is good. No problem
indicated.
◆ If the light is off more than 15 seconds after startup, no USB
connection is detected. This is normal if no projector is connected.
Disconnect and reconnect power at the Jetdirect server. Make sure a
USB cable connects to a projector and the projector is connected to
power. Try a different USB cable. If the condition persists, the server
or projector is faulty. If possible, repeat with a different server or
projector.
◆ If the light blinks green, the projector is not compatible with the
Jetdirect server. Check for Jetdirect compatibility in the
specifications for the projector model and firmware version — or go
to www.hp.com/support
and look up the model number of your
Jetdirect server.
◆ If the light blinks orange, a hardware problem exists. Disconnect and
reconnect power at the Jetdirect server. If the condition persists,
disconnect and reconnect power in each of the following conditions:
❑ No USB cable (blinking orange indicates the server is faulty),
then —
❑ USB cable plugged into onl y the server (blinki ng orange
indicates the cable is faulty), then —
❑ USB cable plugged into the server and projector (blinking orange
indicates the projector is faulty).

3. LAN 10/100 lights:
◆ If one light is on, a network connection is established at 10 Mbps or
100 Mbps. No problem indicated.
◆ If both lights are off, no network is detected. See “Resolving
Communication Problems with the Network,” below.
Resolving Communication Problems with the Network
Check the following items to verify that the projector server is communicating
with the network.
1. Are there any physical connection problems between the workstation or
file server and the HP Jetdirect projector server?
◆ Verify network cabling, connections, and router configurations.
◆ Verify that network cable lengths meet network specifications.
◆ Verify that network settings have been properly configured.
2. Are your network cables connect ed properly?
Make sure that the projector is attached to the network using the
appropriate HP Jetdirect projector server port and cable. Check each cable
connection to make sure it is secure and in the right place. If the problem
continues, try a different cable or network port on the hub or switch.
3. Is autonegotiati on properly configured?
The speed and communication mode on the projector server must match
the network for proper operation.
The server’s RJ-45 network connector
has indicator lights to identify the
10 Mbps
100 Mbps
connection speed. Verify that either the
10 Mbps or 100 Mbps light is on.
4. Is the projector server connected to an
802.1X network and properly configured
for EAP/802.1X operation?
The network must support the Extensible Authentication Protocol (EAP)
method configured for use on the server.
Verify the configuration of the network’s 802.1X port. If it does not allow
guest or temporary access, you may need to preconfigure the Jetdirect
projector server for 802.1X operation before connection to your network.
This is done using an isolated LAN, or through a direct computer-to-Jetdirect
server connection using a cross-over cable.

TCP/IP Overview
Introduction
This appendix is intended to provide information to help you gain a basic
understanding of TCP/IP.
Similar to a common language that people use to communicate with each
other, TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of
protocols designed to define the way computers and other devices
communicate with each other over a network.
TCP/IP is rapidly becoming the most used set of protocols. The main reason
this is happening is the fact that the Internet is based on TCP/IP. If you have
a network that you wish to connect to the internet, you must be using TCP/IP
to communicate.

When information is sent across the network, the data is broken down into
small packets. Each packet is sent independently of one another. Each packet
is encoded with IP information, such as the IP address of the sender and
receiver. IP packets can be routed over routers and gateways, devices that
connect a network with other networks.
IP communications is connectionless. When IP packets are sent, there is no
guarantee that they arrive at their destination in the proper sequence. That task
can be performed by higher level protocols and applications thereby allowing
IP communications to be efficient.
Each node or device that will communicate directly onto the network requires
an IP address, including HP Jetdirect-connected devices.
ENWW 90
Transmission Control Protocol (TCP)
TCP handles breaking the data into packets and recombining the packets on
the receiving end by providing a connection-oriented, reliable, and guaranteed
delivery service to another node on the network. When data packets are
received at their destination, TCP calculates a checksum for each packet to
verify the data is not corrupt. If the data in the packet has been corrupted during
transmission, TCP discards the packet and requests that the packet be resent.
User Datagram Protocol (UDP)
UDP provides similar services to TCP. However, UDP does not acknowledge
data receipt and supports request/reply transactions with no added reliability
or guarantee of delivery. UDP is used when acknowledgment and reliability
are not required, such as during a “discovery broadcast.”
IP Address
Every host (workstation or node) on an IP network requires a unique IP address
for each network interface. This address is a software address that is used to
identify both the network and specific hosts located on that network. Each IP
address can be divided into two separate parts: the network portion and the
host portion. It is possible for a host to query a server for a dynamic IP address
each time the device boots-up (for example, using DHCP and BootP).
Note When assigning IP addresses, always consult the IP address
administrator. Setting the wrong address can disable other
equipment operating on the network or interfere with
communications.
IP Address: (Network Portion)
Network addresses are managed by an organization in Norfolk, Virginia
recognized as InterNIC. InterNIC has been contracted by the National Science
Foundation to manage the Internet addresses and domains. Network addresses
are distributed to organizations that are in turn responsible for making sure all
attached devices or hosts on the network are properly numbered. For more
information on the network portion of an IP address, see “IP Address Structure
and Class” and “Subnets” later in this appendix.
NWW TCP/IP Overview 91
IP Address: (Host Portion)
Host addresses numerically identify specific network interfaces on an IP
network. Usually a host has only one network interface; thus, only one IP
address. Because no two devices can share the same number at the same time,
administrators typically maintain address tables to assure correct assignment
of addresses in the host network.
IP Address Structure and Class
An IP address is comprised of 32 bits of information and divided into 4 sections
containing 1 byte each section or 4 bytes total: xxx.xxx.xxx.xxx
For efficiency in routing, networks were broken down into three classes, so
routing can begin simply by identifying the leading byte of information in the
IP address. The three IP addresses that InterNIC assigns are class A, B, and
C. The network class determines what each of the four IP address sections
identify as shown in Table A.1
Table A.1 IP Address Class Format
:
Class First Address
Byte xxx.
A Network. Host. Host. Host
B Network. Network. Host. Host
C Network. Network. Network. Host
As illustrated in Table A.2

, each network class differs by the leading bit
identifier, the address range, the number of each type available, and the
maximum number of hosts each class allows.

Configuring IP Parameters
TCP/IP configuration parameters (such as IP address, subnet mask, default
gateway) can be configured on the HP Jetdirect projector server in a variety
of ways. These values can be configured manually (for example, through the
embedded Web server, the arp and ping commands, and HP management
software), or they can be automatically downloaded using DHCP or BOOTP
each time the server is turned on. For configuration methods, see Chapter 3
When powered on, a new HP Jetdirect projector server that is unable to retrieve
a valid IP address from the network will automatically assign itself a default
IP address. The default IP address will depend on the type of network to which
the server is connected. On a small private network, a technique called
link-local addressing is used to assign a unique IP address in the range of
169.254.1.0 to 169.254.254.255, which should be valid. On a large or
enterprise network, a temporary address of 192.0.0.192 will be assigned until
it is properly configured for your network. The IP address configured on your
projector server may be determined by inspecting the projector’s on-screen
Help menu.
Dynamic Host Configuration Protocol (DHCP)
DHCP allows a group of devices to use a set of IP addresses that are
maintained by a DHCP server. The device or host sends a request to the server,
and if an IP address is available, the server assigns it to that device.
.
BOOTP
BOOTP is a bootstrap protocol used to download configuration parameters
and host information from a network server. BOOTP uses UDP for its
transport. In order for devices to boot and load configuration information into
RAM, they must communicate through the bootstrap protocol BOOTP as a
client with their server.
To configure the device, the client broadcasts a boot request packet containing
at least the hardware address of the device (HP Jetdirect projector server
hardware address). The server answers with a boot reply packet containing
the information the device needs to configure.
NWW TCP/IP Overview 93
Subnets
When an IP network address for a particular network class is assigned to an
organization, no provision is made for more than one network being present
at that location. Local network administrators use subnets to partition a
network into several different subnetworks. Splitting a network into subnets
can result in better performance and improved use of limited network
address space.
Subnet Mask
The subnet mask is a mechanism used to divide a single IP network into several
different subnetworks. For a given network class, a portion of an IP address
that would normally be used to identify a node is used, instead, to identify a
subnetwork. A subnet mask is applied to each IP address to specify the portion
used for subnetworks, and the portion used to identify the node. For example,
see Table A.3
Table A.3 Example: Subnet Mask 255.255.0.0 Applied to Class A
Class A Network Address 15 xxx xxx xxx
Subnet Mask 255 255 0 0

As illustrated in Table A.3
, the Class A IP network address “15” has been
assigned to company ABC. To allow additional networks at company ABC’s
site, the subnet mask of 255.255.0.0 is used. This subnet mask specifies that
the second byte of the IP address will be used to identify up to 254 subnets.
Using this designation, each device is uniquely identified on its own subnet,
but company ABC can incorporate up to 254 subnetworks without violating
their assigned address space.
ENWW TCP/IP Overview 94
Gateways
Gateways (routers) are used to connect networks together. Gateways are
devices that act as translators between systems that do not use the same
communication protocols, data formatting, structures, languages, or
architectures. Gateways repackage the data packets and change the syntax to
match that of the destination system. When networks are divided into subnets,
gateways are required to connect one subnet to another.
Default Gateway
The Default Gateway is the gateway or router that, if not specified, will be
used to move packets between networks. It is specified by an IP address.
If multiple gateways or routers exist, then the default gateway is typically the
address of the first, or nearest, gateway or router. If no gateways or routers
exist, then the default gateway will typically assume the IP address of the
network node (such as the workstation or HP Jetdirect projector server).
Syslog Server
A syslog server is a system on the network (typically a UNIX system) that can
receive and log syslog messages from other devices on the network. Syslog
messages allow administrators to monitor status or troubleshoot network
devices.
A syslog server requires software that provides syslog capabilities running on
the server. UNIX systems provide a daemon, syslogd, that monitors User
Datagram Protocol (UDP) port 514 for incoming messages. The messages are
processed depending on their priority and on how syslogd is set up to operate.
You can configure the HP Jetdirect projector server with the syslog server’s
IP address. When a syslog server is configured, both the HP Jetdirect projector
server and attached device can send syslog messages using UDP.
NWW TCP/IP Overview 95
The syslog server may not receive all syslog events from the HP Jetdirect
projector server:
● UDP does not guarantee delivery of messages.
● The HP Jetdirect projector server attempts to eliminate duplicate messages
(to minimize unnecessary network traffic).
● The volume of messages sent by the HP Jetdirect projector server is
configurable.
Methods to configure HP Jetdirect syslog parameters include BOOTP, DHCP,
the embedded Web server, and management software. The syslog
configuration command or parameter entries may vary depending on the
method used. For more information, see the applicable sections in this guide.
Selected syslog parameters on the HP Jetdirect projector server are listed in

uses local user values of local0 through local7 to isolate
individual or groups of projector servers.
