Connecting the switch to the network
Before you connect the switch to the network, verify that all its basic settings are correct.
Connecting your switch to the network through twisted pair
cables
The 10/100Base-TX and 1000Base-T ports of the H3C S7500E switches use RJ-45 connectors and
support MDI/MDI-X auto-sensing. Use category-5 twisted pair cables or above to connect the Ethernet
ports of your switch to the network. For more information about twisted pair cables, see " Appendix D
Cables ."
To connect your switch to the network through twisted pair cables:
1. Plug one end of the twisted pair cable into the RJ-45 Ethernet port of your switch.
2. Plug the other end of the twisted pair cable into the RJ-45 Ethernet port of the access device in the
network.
3. Examine the port LEDs for incorrect connection.
For more information about the LED status, see "
Appendix C LEDs ."
Connecting your switch to the network through optical fibers
WARNING!
To avoid injury to your eyes, do not stare at the optical interfaces when connecting optical fibers.
You can install a transceiver module (see " Installing FRUs ") in a fiber port and use optical fibers to
connect the port to the network. For more information about the optical fibers, see " Appendix D Cables ."
The installation of different optical fiber connectors is similar.
To connect your switch to the network through optical fibers:
1. Install a transceiver module into the port.
2. Remove the dust cover of the optical fiber connector, and clean the end of the optical fiber.
3. Remove the dust plug of the transceiver module, plug one end of the optical fiber into the
transceiver module in the switch, and plug the other end into the transceiver module in the peer
device.
