Externally powered units: If not using PoE+, connect the P0 port
to the network using an Ethernet cable, or connect the P1 port to
the network with the appropriate cable (fiber transceiver or direct­attach cable is required).

Daisy-chain configuration: Once network connection is
established to one unit, you can daisy chain additional units by
connecting Ethernet cables between devices using their P0 and/or
P1 ports. Keep in mind that the number of units supported in this
configuration is limited by bandwidth (total aggregate streams
must be less than 1 Gb/s).

NOTE: PoE+ power is only supplied to the unit connected
the network. All other units in the daisy-chain must have an
external power supply.

Establishing Connection

N24X2 devices are shipped with DHCP as their default IP mode. The IP address is
assigned automatically based on the network DHCP server. If no DHCP server is found,
the unit will use Auto IP mode instead (with a default IP address of 169.254.xxx.xxx).

Before using your N24X2 unit, it must be configured using the free N-Able device
management software. However, you will not be able to configure units until they are in
the same subnet as the host computer. The sample steps below show how the required
changes (to the host computer’s IP settings) are made in a Windows environment.

Steps for IP address configuration (for Windows 8):

1. From the Control Panel > Network and Internet dialog box, select Network and
Sharing Center.

2. Select Change adapter settings.

3. Select the wired interface connected to your AV network.

4. Click the Properties button.

5. Scroll down in the list to the Internet Protocol Version 4 (TCP/IPv4) option.
Highlight it and click the Properties button.

6. Enable the Use the following IP address option, and enter the static IP address

provided to you by your network administrator.

NOTE: If the computer does not need Internet access, you can simply enter a unique

169.254.xxx.xxx IP address with a 255.255.0.0 Subnet mask. Please contact your

network administrator if you are unsure of how to configure the existing interface. If the
computer has a statically-assigned IP address, click on the Advanced button. Then click
Add to enter a unique 169.254.xxx.xxx address with a subnet of 255.255.0.0.

Steps for auto discovering devices on the network:

1. Use the host computer to download and install the latest version of N-Able:

PC version ­Mac version -

2. Attach your N24X2 unit(s) to the layer-3 network switch.

3. Disable the wireless adapter on your computer (it must be hard-wired to the
switch).

4. Connect the host computer to the layer-3 network switch.

5. Open the N-Able application.

If all devices do not appear automatically, click the Auto Discover button on the
Unit Management tab. This issues a broadcast command that will discover all units
even if they are not in the same IP subnet.

Logging in Using N-Able Software

Once the host IP address is configured properly, you can view all discovered units using
the N-Able software. Access the N24X2 units from the following tabs:

• Unit Management tab - N2400 Encoder/Decoder is listed in the Type field.

• Video Matrix tab - N24X2 units are found on the N2400 sub-tab of this screen.

Double-click the unit’s name (in one of the lists mentioned above) to view its control
page. If prompted, enter admin and password for the default username and password.
Once logged in, you can change the username and password (using the options on the
unit’s Settings page).

NOTE: If you would like for N-Able to support auto-login to your units, make sure N-Able’s
Device Auto-login settings match the unit’s username and password (by selecting N-Able
> Settings from the N-Able tool bar).

NOTE: N24X2 units force HTTPS connections, so your web browser may give you a
security warning. N-Able on Windows will ask you to download OpenSSL for Windows to
connect HTTPS.

Video/USB Switching Options

USB Follows Video: By default, units can be switched using N-Able without modifying

the configuration. When you switch video streams (using the matrix as shown above)
the USB functionality will follow the video.

Independent USB Switching: Use N-Able’s USB Matrix tab to switch USB control
(without affecting video).

Independent Video Switching: To switch video streams without affecting USB control,
first select N-Able > Settings from N-Able’s main menu. When the N-Able Settings
dialog box is displayed, disable the USB follows Video switching for KVM units. Now you
can use the Video Matrix to switch video streams only.
