Abstract

An apparatus and method tests simple network management protocol (SNMP) cards. Each of the SNMP cards includes an I2C port and a GIPO port. The method predefines an I2C address for each of the slots of a circuit board, sets an interval time for sending communication data by each of the SNMP cards, and determines one of the SNMP cards as a slave device and the other SNMP cards as master devices by detecting an I2C address of each of the GPIO ports. The method controls one of the master devices to send the communication data to the slave device at the interval time, controls the slave device to send a response message to the master device when the communication data is received, and generates information that indicates that an SNMP card corresponding to the master device has malfunctioned when the response message is not received.
