For more information, seeH3C S9500E Switch SeriesNetwork Management and Monitoring Command Reference.Connecting the switch to the network through an AUX cableYou need an AUX cable when configuring a switch with the remote modem dial-up approach.An AUX cable is an 8-core shielded cable. At one end of the cable is an RJ-45 connector and at the otherend is a DB-9 (male) connector. Plug the RJ-45 connector into the AUX port of the switch and the DB-9(male) connector into the DB-9 (female) port of the modem. An AUX cable is the same as a console cable.For more information, see Figure 1 and Table 1.To connect the AUX port:1. Plug the RJ-45 connector of the AUX cable into the AUX port of the switch.2. Plug the DB-9 (male) connector at the other end into the serial port of the modem.Connecting the switch to the network through an Ethernettwisted pair cableThe 10/100/1000Base-T copper ports of the switch support MDI/MDI-X auto-sensing. They areconnected to the network through category-5 or above twisted pairs that are equipped with RJ-45connectors.To connect a 10/100/1000Base-T port:1. Plug one end of an Ethernet twisted pair cable into the copper Ethernet port (RJ-45 port) to beconnected on the switch.2. Plug the other end of the cable into the RJ-45 port of the peer device.NOTE:No Ethernet twisted pair cables are shipped with the switch. Prepare them yourself.
