Installation Summary
This guide will show you how to physically install the router and make it accessible
from both the WAN and your LAN. Advanced features, which are explained in the
User’s Guide, can then be configured by you or a network administrator using a
computer on your LAN, or from a remote office over the WAN.
For a first-time installation, allow about 20 minutes for each of the following:
❏
Looking through this manual and understanding the steps
❏
Installing the router and cables
❏
Setting up a computer to access the router through your Internet browser
❏
Performing the basic LAN and WAN configurations
Add or subtract time depending on your experience and installation site readiness.
Subsequent router installations can go much faster.
NOTE
Your router may have already been pre-configured by your network administrator,
which would further simplify your installation tasks.
Gather the necessary information
Ask your network administrator or IT department for the information listed in the
configuration worksheet on page 9. After physically installing the router, you will
enter this information using the router’s graphical user interface (GUI) to set up
basic network connectivity.
NOTE
The configuration worksheet contains the minimum information necessary to make
the LAN and WAN interfaces functional in most remote-office installations. Not all
parameters visible in the graphical interface are represented in the worksheet. The
goal of this Setup Guide is to make the router accessible over the WAN to a network
administrator who can later configure the advanced features.

Before you begin
Perform a power-on test
To verify that the router is fully functional before installation, plug in just the power
adapter (no other cables) and observe the LEDs on the front panel. When power is
applied, the SYS (System Status) LED will initially be red, then blink green as it
runs internal tests. When the system tests complete after about a minute, the SYS
LED turns to a steady green to indicate operational status.
If a problem is detected, the SYS LED will remain red after the power-on test
completes. Should this happen, restart the router by unplugging the power adapter
momentarily. If this does not clear the problem, note whether any other LEDs are
red and contact your network administrator or place of purchase.

WARNING!
The AC–DC power adapter cable functions as the power
disconnect device and ground connection. Always connect the
power adapter cable first (before other cables) and disconnect it
last, so that the unit is grounded through the power supply.

Installing the router
Installation shortcut for IT professionals
If you are an IT professional or have previously installed a Kentrox QoS router, the
abbreviated steps on this page may be all you need. If you are new to installing this
type of equipment, the pages that follow offer a detailed explanation of each step.
Step 1: Install the router on a wall, in a rack, or place it on a desk top.
Step 2: Apply power to the router, then connect a computer to one of the Ethernet
LAN ports using the included Ethernet cable (or equivalent). Since the
router is by default a DHCP server on the LAN side, be sure to set the
computer to obtain its IP address automatically. If you are modifying the
LAN IP configuration, do not connect devices other than your console to the
LAN until the configuration changes have been made. See “Changing the
LAN interface configuration” on page 21 for more information.
Step 3: Reboot the computer you will use to configure the router. Open your
Internet browser and enter 192.168.1.1 in the address field. This is the
default LAN-side IP address of the router. Enter the user name “admin” at
the login prompt, but no password. The router’s home page opens, as shown
in Figure 5 on page 19.
Step 4: To prevent unauthorized access to the router, navigate to the Configure >
System > Users page, and set a password for the default user, Admin.
Step 5: If a network administrator will manage the router from a remote location, go
to the Configure > System > Management Access page and select http,
telnet, and/or any other check boxes in the untrusted zone, as specified by
the administrator.
Step 6: Enter the information from the worksheet above into the appropriate
configuration pages.
Step 7: Attach the WAN and LAN cables.2
Step 8: Go to the Configure > System > Restart page to save your configuration
changes to non-volatile memory. If changes were made to the LAN IP
address or DHCP options, you may have to restart each PC on the LAN side
of the router.
Step 9: Go to the Monitor > Traffic > Ping page to validate your WAN connectivity
by pinging a device on the WAN, such as the default gateway.
2
If you purchased the modem option, you can also connect the modem cable at this time.
Both the modem and T1 cables must be made with a minimum of 26 AWG cable.
Contact your local T1 service provider for T1 cable requirements.
15
For conceptual information on router features, see the User’s Guide. You can also
click Help in the router’s interface for information on the page you are viewing.
Step 1: Mount the router on a wall or in a rack
While the Kentrox router can be used on a desk top or table top, it may also be
mounted on a wall or in a rack for space efficiency and cable management. For ease
of handling, disconnect the power cable before wall- or rack-mounting the router.
Two 1-inch, #8 screws and anchors are included with the router. The anchors can be
used when attaching to drywall. Use the screws alone if attaching to a plywood
mounting panel. You will need longer screws—at least 1.25”—if attaching to a stud
through drywall.

a
b
c
d
Drill two starter holes for the screws (or anchors) 7” apart.3 Align the
screw holes vertically on the wall if you want to position the front panel
LEDs to the side, as shown in Figure 2.
If mounting on drywall, screw the anchors into the holes, then the screws
into the anchors. Leave 1/4” between the screw heads and the wall.
Position the router over the screw heads, and slide the router downwards
and diagonally approximately 1/4” so that the screw heads are firmly positioned in the narrow part of the mounting slots.
Power on the router, and proceed to Step 2 on page 18.

Mounting the router on a wall
Use the drilling guides on the left side of this page to mark the screw hole locations.
Installing the router
Rack mounting instructions
The router can also be mounted in a 19” rack, as shown in Figure 3, using the
optional rack mounting kit (Kentrox catalog #77912). Install the rack with enough
space around it for adequate ventilation: at least 1/8” above and 1” on each side.
a
Hold the brackets up to the rack to line up the screw holes. Depending on
the type of rack you have, you may need to rotate the brackets to find screw
holes that align—the spacing between the holes on the ends of the brackets
are 1” and 1¼” to accommodate different rack types.
b
With the orientation of the brackets in mind, attach them to the sides of the
router using three self-tapping, 6-32 x 5/16” machine screws on each side.
The screws are included in the rack mounting kit.
c
Hold the router and bracket assembly in position in the rack with one hand,
and insert screws through the holes in the brackets and rack with the other.
Tighten the screws with a screw driver.
d
Power on the router, and proceed to Step 2 on page 18, “Set up a computer
to access the router.”
Figure 3:
Rack mounting the router
17
Step 2: Set up a computer to access the router
Unless your network administrator or reseller has already configured the router—in
which case you can skip ahead to Step 7 on page 23—you will need to change a few
settings that are specific to your network.
The easiest way to do this is to connect a computer to the router and use an Internet
browser to access the routers’s configuration pages, as described below.
CAUTION!
To avoid disrupting network traffic, do not connect the router to an existing
LAN until after you have completed steps 2 through 6.
a
Make sure your computer is set to be a DHCP client. The router is by
default a DHCP server on the LAN side, so any computer initially connecting to it must be set up as a DHCP client. In other words, the computer you
are attaching must be configured to obtain an IP address automatically
from the router.
The procedure for setting up a computer to obtain an IP address automatically varies according to the computer’s operating system. Typically it is a
TCP/IP configuration option. Consult your operating system’s online help
or user manual for details.
b
Connect the computer to one of the router’s 10/100 Ethernet LAN ports as
shown in Figure 4. Make sure the router is still powered on before connecting any cables. The router’s Ethernet LAN ports auto-detect and autonegotiate, so either a straight- or crossover-Ethernet cable can be used.
Check for a green LAN STAT LED on the front panel to verify a good
cable connection before proceeding.
c
If you changed any settings in the computer, restart it to release and renew
the IP address.

Connecting a computer to the router
Alternative connection method (advanced)
You also have the option of attaching a computer to the RS-232 port and setting up
the router using the command line interface (CLI). This is typically done only if it
would be problematic to set up a Dynamic Host Control Protocol (DHCP) client
computer, or for large-scale deployments in which scripts are used to configure
many routers quickly. Refer to the User’s Guide and CLI Reference Guide for more
information about the CLI.
18
Installing the router
Step 3: Access the router’s graphical interface
Start the computer’s Internet browser. Ignore any messages that may appear about
the browser being unable to display your default web page, and enter 192.168.1.1
in the browser’s Address field. This is the default LAN-side address of the router.
When prompted for User Name and Password, enter the user name “admin” at the
login prompt, but no password. Your browser will display the router’s home page,4
Monitor > System, similar to Figure 5.
Figure 5:
The home page displays the router’s status
If this page does not appear in your browser, the most likely causes are:
• A bad cable connection—check to see that you have appropriate cables
(see the User’s Guide) and that they are securely attached.
• The client computer is not properly configured as a DHCP client (i.e., it
must be set to obtain an IP address automatically)—restart the computer
after checking its configuration and/or LAN connection.
Step 4: Set a password for the default user
The default user name, “admin,” has full system access, but is not passwordprotected. You should assign a password immediately for security reasons.
Navigate to the Configure > System > Users page, which initially contains only the
“admin” user. Click Password in the table to open the User Configuration page, and
assign a password for the admin user. Click the OK button to make your changes
take effect.
4
The graphs on the Monitor > System page require Macromedia Flash Player
(www.macromedia.com) be installed on your computer.
Access the router’s graphical interface
19
Exploring the interface
This may be a good opportunity to take a few minutes to explore the interface before
proceeding. Keep these points in mind as you view the graphical interface:
• The graphical user interface (GUI) is browser-based, so its behavior is
similar to Internet Web pages. For example, you can click the Back button
in your browser or press the backspace key to return to the previous page.
• Navigation buttons are on the left side of the page, and are divided into two
general categories—Monitor and Configure. The Configure pages are used
for setting up the router.
• Click Help for more information about any page you are viewing.
• Some of the charts, graphics, or data in the interface are linked to other
pages with additional information. In Figure 5, for example, the event logs
(such as System, Alarm, and Intrusion) can be reviewed just by clicking on
the underlined words. If you are unsure whether something is a link, move
your cursor over it. The cursor shape—and sometimes the color of the
object itself—changes whenever it is positioned over a link.
Step 5: Allow remote access (optional)
If the network administrator will manage the router from a remote location, go to the
Configure > System > Management Access page and in the Enable column of the
untrusted inbound zone, select the http, telnet, and/or any other check boxes
specified by the administrator. Do not allow remote access unless instructed to do
so, as it removes a layer of network defense.
If the router is equipped with the optional modem, specify “cliDialIn” in the modem
Operation list to allow dial-in access to the command line interface (CLI) by the
network administrator. Only model Q2401 routers are equipped with a modem. The
model number is listed on the label underneath the router and on the shipping box.
NOTE
The router’s graphical user interface is not available through the Modem port. Refer
to the CLI Reference Guide for further information about CLI commands available
via modem.
Step 6: Enter the worksheet information
Next, configure the router using the information you gathered in the configuration
worksheet on page 9.
Default LAN interface configuration
The router’s default LAN IP address is 192.168.1.1, and the subnet mask is
255.255.255.0. If you plan to set up a new LAN with the router or replace an
existing router, there is usually no need to change these addresses. The router can
remain a DHCP server with the default IP address and subnet mask.likely you’ll
need to change these addresses. The information is available in the Changing the
LAN interface configuration section.
20
Installing the router
Changing the LAN interface configuration
In some cases it is necessary to disable DHCP or to change the default LAN IP
address and subnet mask. For example, you may want to add the Q2400 router to an
existing LAN via one of its Ethernet LAN ports, or you may need to use static
(fixed) IP addresses in the LAN.
a
Go to the Configure > Interfaces > Ethernet Ports 1-4 page. From the iplan
Controls list, select Edit IP.
„
„
If you already have a DHCP server or you want to use static LAN IP
addresses on the LAN, clear the DHCP Server Enable check box.
–– or –
If you want the Q2400 router to be the DHCP server in the LAN but are
modifying the router’s LAN IP address, change the default IP address
and subnet mask to match the new subnet and click OK. The IP address
ranges will automatically update to reflect the new LAN subnet.
b
At this point, the computer you connected to the router will no longer be
able to communicate with the router, but do not reboot or power down the
router or you will lose all of your changes.
c
Configure the computer to communicate with the router under one of the
following scenarios.
„
„
„
d
If you disabled DHCP in the router because the LAN has an existing
DHCP server, you can now connect another LAN port on the router to
the existing LAN. Restart the computer to make it obtain a new IP
address on the new subnet.
– or –
If you do not have a DHCP server for the new subnet, configure the
computer with a static address on the new LAN subnet. Restart the
computer to make the changes take effect.
– or –
If the router is the DHCP server, restart the computer to make it obtain a
new IP address on the new subnet.
The computer should now be able to communicate with the router. Log in
using the new password, and continue the setup process.
T1 WAN interface configuration
Several settings are required to make the T1 connections to the WAN operational.
a
Go to the Configure > Interfaces > T1 Ports 1-2 page. Configure each of the
T1 WAN ports you are setting up, using the information identified in the
configuration worksheet on page 9. Be sure to enter the IP address and subnet mask in either the PPP or the Frame Relay/DLCI setup.
b
Check the settings in the other sections of the page to ensure they match
the information supplied by your service provider. If you are unsure about
anything on the page, click Help for further information or contact your
system administrator.
Enter the worksheet information
21
Ethernet WAN interface configuration
If you are connecting to a DSL or to a Cable Internet service:
a
Go to the Configure > Interfaces > Ethernet Port 5 page. From the ipwan
Controls list, select Edit IP. Click Static IP Address and enter the router’s
Ethernet WAN IP address and subnet mask.
b
Check all other settings on the page while you are there to ensure they
match the information supplied by your service provider. For example,
your Internet Service Provider may require you to enable PPPoE (Point-toPoint over Ethernet) for the necessary modem handshake sequence. If you
are unsure about anything on the page, click Help for further information
or contact your system administrator.
Default gateway configuration
Next specify the default gateway, which is typically the IP address of your WAN
service provider’s gateway router. Only one default gateway needs to be identified
for the router, even if you set up multiple WAN connections.
a
On the Configure > Router > Routes page, click add in the Default Route
section. This opens a page where you can enter the default Gateway IP
address.
b
On the same page, you must also select the IP interface for the gateway.
DNS Configuration
Now specify the IP addresses of the primary and secondary Domain Name Servers
(DNS) on the Configure > Router > DNS Client page. Obtain at least one DNS
address from your service provider. DNS enables users on your LAN to use humanreadable domain names for network access, such as server1.company.com, instead
of numerical IP addresses such as 123.45.67.8.
NOTE
Only one DNS server can be entered at a time. Always enter the name of the primary DNS server first, the secondary DNS server second, and so forth.
Next, go to the Configure > Router > DHCP page. From the Configure list for the IP
Interface, select Edit DHCP Server Interface. Enter the same DNS addresses and the
domain name and click OK. This enables the router to provide the DNS addresses to
computers on the LAN.
System clock configuration
To ensure that system logs and charts display the correct time of alarms and other
events, go to the Configure > System > Time page. To manually set the current date
and time, proceed to the Set Date and Time page. If the router will derive the current
date and time from an SNTP time server, go to the SNTP Server page and input the
IP addresses of the SNTP servers.
22
Installing the router
Step 7: Connect the cables
To prevent accidental ESD damage, attach cables to the router only when it is
powered on. Refer to Figure 6 for port locations on the back of the router.
a
Attach up to four LAN devices to the 10/100 auto-negotiating Ethernet
ports on the rear of the router using straight or crossover Ethernet cables.
b
Attach T1 cables to the router’s T1 WAN ports and your T1 circuit jack or
termination device.
c
If you are also setting up a WAN connection using DSL or cable, attach
one end of an Ethernet cable to the 10/100 WAN port and the other end to
the DSL/cable modem. If the DSL/cable modem port does not auto-negotiate, you may need a cross-over Ethernet cable. Ethernet 10/100 WAN port
pin assignments are provided in the Q-Series User’s Guide.
d
If your router has the optional built-in modem, attach one end of the phone
cable to the router’s modem port and the other end to a phone jack.
NOTE
Both the T1 and modem cables use a minimum of 26 AWG cable. Consult your local
T1 service provider for minimum requirements if you are making your own T1 cable.
Cable pinouts are provided in the Q-Series User’s Guide.

You have made the proper WAN and LAN connections if the corresponding frontpanel STAT LEDs and the rear-panel ACT LEDs are green. The front panel Modem
LED is green if the router is equipped with the optional modem and it is configured
for use. If these LEDs are not green, the problem is most likely one of the following:
•
The cable is plugged into the wrong connector or wall jack
•
The cable is not completely plugged in—reconnect both ends of the cable
•
The cable is damaged or defective, or the wrong type of cable was used—
try another cable appropriate for the connection
•
The interface was configured incorrectly—compare your setup with the
configuration worksheet; contact your network administrator or service
provider to verify the worksheet information if no mistakes are found
•
The service is not available—contact your service provider for resolution
Connect the cables
23
Step 8: Save your configuration and restart
When you make changes to the default configuration, the router stores those
changes in RAM. Your changes will be lost if you lose power or restart the system
without first saving those changes to non-volatile memory.
a
Take a few minutes now to save the changes you have made so far and
restart the router to refresh IP connections. Go to the Configure > System >
Restart page to save your changes and restart the router.
b
Once you have restarted the router, restart each attached PC on the LAN to
release and renew the DHCP configurations.
Note that if you plan to explore advanced features of the router, you may decide to
test more complicated configuration changes without saving them, so that you can
test those changes and undo any mistakes with a system restart.
Step 9: Test access to the WAN
Verify that the WAN interface is functional by running a ping test from the router to
a known host on the WAN, such as the default gateway.
To do this, go to the Monitor > Traffic > Ping page, and enter the name or IP address
of the remote host. If successful, you will see detailed information about the ping
that includes the line “1 transmitted, 1 received, 0 lost.” An unsuccessful ping test
will result in a “Request timed out” message.
If you are able to access the WAN, your initial router setup is complete. Refer to the
User’s Guide for information on setting up advanced features.
Should the ping test fail, check to make sure you entered the correct IP address and
interface for the default gateway on the Configure > Router > Routes page. If they
appear to be correct, compare the settings on the Configure > Interfaces > T1 Ports 12 page with your configuration worksheet, and—if necessary—with the original
connection specifications from your WAN service provider or network
administrator. You should also verify the cable connection by checking to see that
the WAN STAT LED on the front panel is green.
If all else fails...reset
Should you encounter unexpected behavior after configuring the Kentrox router,
and you are unable to determine the cause, you can reset the router to its factory
default configuration.
To do this, either hold in the reset button on the router’s back panel for 12 seconds,
or go to the Configure > System > System Restart page in the interface and click the
“reset to factory defaults” check box. The reset button is recessed to prevent
accidental resets, so you will need a small pointed object, such as a pen or paper clip
end.
Additional troubleshooting information and documentation can be found on these
Kentrox web pages: www.kentrox.com/support and www.kentrox.com/Q-Series. A
list of factory default values is provided in the Q-Series User’s Guide.
