Caution

- This device is designed only for an operating voltage range from 19,2 to 28,8 V

DC. Do not use a higher voltage; this could destroy the Router and other devices.

- The Security Router does not have an on/off switch. The operating voltage must

be switched on by the facility in which the device is integrated.

Caution

You should activate and synchronize the time server or set the system time manu-

ally if you are using certificates in virtual private networks (VPNs) or simple network

management protocol (SNMP). An inaccuracy in the system time can cause the vir-

tual private network (VPN) to malfunction.

You should synchronize the system time with a time server after each Router re-

boot and after you load the default settings. Or you can set the system time manu-

ally.

Caution

- The default system access information for the Security Router is included in this

document. Unauthorized individuals can use this access data to gain access to the

Router's web browser and cause damage. Be sure to change these system default

access settings.

- Some services may be blocked by a firewall. You may need to deactivate the fire-

wall. By deactivating the firewall, the PC is no longer protected against viruses or

other attacks. Only deactivate the firewall when your PC is sufficiently protected by

other measures.

- A single port can only properly execute one service. If multiple services are as-

signed to a port, the port can no longer execute any service. Be sure to assign only

one service to any port.

Note

- The IP protocol reserves certain IP address ranges for special purposes (such as

multicasting). Do not assign IP addresses in the range from 127.0.0.0 –

- This device is intended for use in applications as described in the operating in-

structions only. Using this device in non-approved applications will lead immedi-

ately to the expiration of all guarantee and warranty claims on the part of the oper-

ator against the manufacturer.
