Relay apparatus
First Claim
1. A relay apparatus connected to a plurality of communication lines to perform data relay between the plurality of communication lines,the relay apparatus comprising:
- a control circuit and an EEPROM in which a setting in the relay apparatus is stored,a receiver unit that receives rewrite information, which includes information for changing the setting in the EEPROM of the relay apparatus, from a source apparatus via any of the plurality of communication lines;
a setting changer unit that changes the setting of the relay apparatus in accordance with the rewrite information;
a change information sending unit that sends the rewrite information to another relay apparatus existing in a local network; and
a test mode transition unit that changes an operation mode of the relay apparatus into a test mode upon receipt of a test mode transition instruction, which instructs transition to the test mode, from any of the communication lines, when the setting in the EEPROM is changed based on the rewrite information.

6. A relay apparatus connected to a plurality of communication lines to perform data relay between the plurality of communication lines,
the relay apparatus comprising: -
a control circuit and an EEPROM in which a setting in the relay apparatus is stored, a receiver unit that receives rewrite information, which includes information for changing the setting in the EEPROM of the relay apparatus, from a source apparatus via any of the plurality of communication lines; a setting changer unit that changes the setting of the relay apparatus in accordance with the rewrite information; a change information sending unit that sends the rewrite information to another relay apparatus existing in a local network; a completion notifier unit that notifies the source apparatus of a completion notification indicating completion of the change of the setting when the setting changer unit completes the change of the setting; and a trouble information sending unit that sends trouble information indicating presence and absence of a trouble of the relay apparatus in response to a request from the source apparatus;
whereinwhen the completion of the change of the setting is notified, the completion notification of the change of the setting contains the trouble information.
