Instructions for Using a Dial-Up Networks

Using a dial-up network in each mode
When there is a primary server at dial-up destination
When there is a primary server in the local network

This chapter contains explanations about and instructions for using a dial-up network.

Note:

The primary server described in this manual indicates a primary time server which offers time to the workstations on the network.

Using a dial-up network in each mode

Print Server mode:
Because the Internal Print Server polls the primary server for jobs in Print Server mode, it is not recommended that the primary server be located on a dial-up connection. A permanent connection should be used instead.

Remote Printer mode:
In Remote Printer mode, it is possible for the Internal Print Server to operate in this configuration if the router has a proxy reply function. However, unnecessary dial-ups are made when the primary server is down, so it is recommended that a dial-up exclusive connection line is used.

When there is a primary server at dial-up destination

Possible problems below are examined for cases where the Internal Print Server has to operate in this environment.

Note:

A precondition is to use a router which has a NetWare proxy reply function.

For local networks with file servers:

At power-up

Since the local file server is accessed before the primary server, a dial-up is generated. There is no problem since this dial-up is generated only once when the power supply is turned on.

When the Internal Print Server is not correctly configured

Since the local file server is accessed before the primary server, a dial-up is generated. This dial-up is repeated at intervals of approximately 5 minutes. Configure the Internal Print Server correctly to avoid this phenomenon.

During normal operation (standby)

A SPX Watchdog packet is sent according to the NetWare protocol rules. Use a router with a proxy response function to avoid dial-up.

During normal operation (printing)

A dial-up is generated while the printing data is being transferred. This is not a problem because it is a dial-up specific to the dial-up network.

When the primary server is down during operation

A dial-up is generated because connection to the primary server is periodically attempted. Since this is attributable to the automatic re-connection function, turn the printer off and on once.

When the local network file server is down

If the local network file server is unavailable, NetWare may not be able to be used on the local network. In this case, the Internal Print Server will stop print server or remote printer operation and no further dial-ups are generated.

For local networks with no file server:

Depending on the router setting, the NetWare protocol can be used without a file server on the local network. This case also follows the first five described above.

When there is a primary server in the local network

Even if a primary server is installed on the local network, an unnecessary dial-up may be generated depending on the configuration. The following phenomena are common in both the Print Server mode and the Remote Printer mode.

At power-up

Since access is made only to the primary server, no dial-up is generated.

When the Internal Print Server is not correctly configured

Since access is made only to the primary server, no dial-up is generated. However, if an incorrect remote network file server or print server is set as the primary server, an unintended dial-up might be generated. Configure the Internal Print Server correctly to avoid this problem.

During normal operation (standby)

Since access is made only to the primary server, no dial-up is generated.

During normal operation (printing)

Since access is made only to the primary server, no dial-up is generated.

When the primary server is down during operation

Connection to the primary server is periodically attempted, but no dial-up is generated. However, if the router is set to pass SAP packets (Find Nearest Server), an unintended dial-up might be generated. To avoid this, turn the printer off and on once, or do not allow the router to pass SAP packets (Find Nearest Server).
