Step 3: Mount KDS-SW2-EN7
Install KDS-SW2-EN7 using one of the following methods:
- Attach the rubber feet and place the unit on a flat surface.
- Fasten a bracket (included) on each side of the unit and attach it to a flat surface (see www.kramerav.com/downloads/KDS-SW2-EN7).
- Mount the unit in a rack using the recommended rack adapter (see www.kramerav.com/product/KDS-SW2-EN7).
- Ensure that the environment (e.g., maximum ambient temperature & air flow) is compatible for the device.
- Avoid uneven mechanical loading.
- Appropriate consideration of equipment nameplate ratings should be used for avoiding overloading of the circuits.
- Reliable earthing of rack-mounted equipment should be maintained.
Step 4: Connect inputs and outputs
Always switch OFF the power on each device before connecting it to your KDS-
SW2-EN7 and KDS-DEC7 
** KDS-SW2-EN7 and KDS-DEC7 can stream 4K video, requiring a gigabit
Ethernet switch for high quality performance, since the maximum momentary
transfer rate can reach 850Mbps. We recommend using AVoIP Ethernet switches
that support: Multicast forwarding or filtering, IGMP Snooping, IGMP Querier,
IGMP snooping fast leave and Jumbo frame (8000 bytes or larger).
Connecting the audio input/output 
** To achieve specified
extension distances, use the recommended Kramer cables available at
www.kramerav.com/product/KDS-SW2-EN7.
Using third-party cables may cause damage!
Step 5: Connect power
By-default, the device uses PoE for powering the device.
Optionally, you can separately purchase a power adapter to connect to the
product and plug into the mains electricity.
Safety Instructions (See www.kramerav.com for
updated safety information)
Caution:
-
For products with relay terminals and GPIO ports, please refer to the permitted rating for an external connection, located next to the terminal or in the User Manual.
-
There are no operator serviceable parts inside the unit.
Warning: -
Use only the power cord that is supplied with the unit.
-
Disconnect the power and unplug the unit from the wall before installing.
Step 6: Operate KDS-SW2-EN7
Allocating the IP Address via LCD screen menu
KDS-SW2-EN7 IP default address is 192.168.1.39. By default, DHCP is enabled,
and assigns an IP address to the device. If DHCP Server is not available, for
example, in case a device is connected directly to the laptop, that device
gets the default IP address. If this IP addresses is already in use, the
system searches for a random unique IP in the range of 192.168.X.Y. the
allocated IP address can be identified using the LCD screen menu.
To allocate the IP address via LCD screen Menu:
- Connect the device to the 24V DC power adapter and connect the adapter to the mains electricity. The ON LED lights green, and the LINK LED flashes (indicating that no streaming activity is detected).
- Use the Navigation button to view the assigned IP address on the LCD screen:
▪ DEV STATUS > LAN1 Status
▪ DEV STATUS > LAN2 Status (if the Service port connected as well).
Setting Channel Number
Each encoder requires a unique channel number, and the connected decoders
should be tuned to that encoder channel. You can set the channel number via
the LCD screen menu or the embedded web pages.
To set the channel number for KDS-SW2-EN7 via LCD screen menu:
- Connect the device to the 24V DC power adapter and connect the adapter to the mains electricity. The ON LED lights green, and the LINK LED flashes (indicating that no streaming activity is detected).
- In the LCD screen menu, go to DEV SETTINGS > CH DEFINE.
- Change channel number using arrow buttons and set a unique channel number.
- Press Enter to save your selection.
