8. Connection (Cascading Multiple KVM Switches)
To cascade two or more NetCommander KVM switches off the
NetCommander IP, follow the instructions below. Connect up to 256
computers* using any combination of B072-008-1 and B072-016-1 KVM
switches. You can only cascade 1 extra level of KVM switches onto the
NetCommander IP KVM.
* When all 16 ports have a B072-016-1 cascaded from them.
Note: Access and Target Settings will be limited when cascading off of
the NetCommander IP KVM Switch.
Security for the computers/servers attached to a cascaded KVM cannot
be set up using the Web Confi guration Interface. The only security
available is via the cascaded KVM’s OSD. If a user has access to the
cascaded port, they will have access to all computers/servers attached to
the cascaded KVM switch.
Once the cascaded KVM Switch is accessed from the NetCommander IP
KVM Switch, the only way to access the attached computers/servers is via the Keyboard Hotkeys or the OSD. If OSD security is set to on, the only
way to access the attached computers/servers is by using your password to access the OSD. See changing the lower-level OSD Hotkeys on page 18.
The NetCommander IP will not store the Video and Mouse settings for computers/servers attached to a cascaded KVM Switch. The user will need
to adjust the Video and Mouse settings each time they access a computer/server attached to a cascaded KVM switch.

9. Initial Settings (Default IP Address)
9.1 Networks with a DHCP Server
By default, the NetCommander IP automatically assigns an IP address from a DHCP (Dynamic Host Confi guration Protocol) server on the connected
network. The DHCP server provides a valid IP address, gateway address and subnet mask. Have your Network Administrator identify the newly assigned
IP Address from the DHCP server. To help locate the IP Address in the DHCP server, reference the MAC Address located on the underside of the
NetCommander IP. The device number (D.N.) can be found in the same location.
9.2 Networks without a DHCP Server
If no DHCP server is found on the network, the NetCommander IP boots with the static IP address:192.168.0.155.
Note! If a DHCP server later becomes available, the unit picks up the IP settings from DHCP server. To keep the static IP address, disable
DHCP – explained on page 7.
10. Static IP Addresses for Multiple KVM Switches
When you want to connect more than one B072-016-1-IP KVM Switch to the same network, and there is no DHCP server; or, you want to use static IP
addresses, do the following:
Connect the NetCommander IPs, one at a time, and change the static IP address of each unit before connecting the next unit.
