However, there is no real time clock inside RX3141; RX3141 relies on external time servers to maintain correct time. RX3141 allows you to configure up to three external time servers. Make sure that the “Enable” check box is checked to activate the SNTP (Simple Network Time Protocol) service for time keeping.

RX3141 User’s Manual 12 Chapter 12. IP Addresses, Network Masks, and Subnets IP Addresses, Network Masks, and Subnets 12.1 IP Addresses This section pertains only to IP addresses for IPv4 (version 4 of the Internet Protocol). IPv6 addresses are not covered. Note This section assumes basic knowledge of binary numbers, bits, and bytes. For details on this subject, see Appendix 12.
Chapter 12. IP Addresses, Network Masks, and Subnets RX3141 User’s Manual 12.2 Network classes The three commonly used network classes are A, B, and C. (There is also a class D but it has a special use beyond the scope of this discussion.) These classes have different uses and characteristics. Class A networks are the Internet's largest networks, each with room for over 16 million hosts. Up to 126 of these huge networks can exist, for a total of over 2 billion hosts.
RX3141 User’s Manual Chapter 12. IP Addresses, Network Masks, and Subnets 12.3 Subnet masks Definition mask A mask looks like a regular IP address, but contains a pattern of bits that tells what parts of an IP address are the network ID and what parts are the host ID: bits set to 1 mean "this bit is part of the network ID" and bits set to 0 mean "this bit is part of the host ID." Subnet masks are used to define subnets (what you get after dividing a network into smaller pieces).
RX3141 User’s Manual 13 Appendix Troubleshooting This appendix suggests solutions for problems you may encounter in installing or using the RX3141, and provides instructions for using several IP utilities to diagnose problems. Contact Customer Support if these suggestions do not resolve the problem. Problem Power LED does not illuminate after product is turned on.
Appendix RX3141 User’s Manual Problem PCs cannot display web pages on the Internet. Troubleshooting Suggestion Verify that the DNS server specified on the PCs is correct for your ISP, as discussed in the item above. You can use the ping utility, discussed in the following section, to test connectivity with your ISP’s DNS server. Configuration Manager Program If you have not changed the password from the default, try using You forgot/lost your “admin” as the user ID and “admin” for the password.
RX3141 User’s Manual Appendix Figure 13.1. Using the ping Utility If the target computer cannot be located, you will receive the message “Request timed out.” Using the ping command, you can test whether the path to the RX3141 is working (using the preconfigured default LAN IP address 192.168.1.1) or another address you assigned. You can also test whether access to the Internet is working by typing an external address, such as that for www.yahoo.com (216.115.108.243).
Appendix RX3141 User’s Manual Figure 13.2. Using the nslookup Utility There may be several addresses associated with an Internet name. This is common for web sites that receive heavy traffic; they use multiple, redundant servers to carry the same information. To exit from the nslookup utility, type exit and press at the command prompt.
