5 Connecting cables

Connecting a twisted pair cable

The router provides 1000BASE-T ports. These ports use RJ-45 connectors and support auto-MDI/MDI-X. Use twisted pair cables of category-5 or above to connect the Ethernet ports of your router to the network. For more information about twisted pair cables, see "Ethernet twisted pair cable." in H3C CR16000-M Routers Hardware Information and Specifications.

To connect your router to the network through a twisted pair cable:

1.     Connect one end of the twisted pair cable to the RJ-45 Ethernet port of your router.

2.     Connect the other end of the twisted pair cable to the RJ-45 Ethernet port of the access device in the network.

Connecting your router to the network through optical fibers

About transceiver modules and optical fibers

To connect a fiber port, install an SFP, SFP+, or QSFP28 transceiver module in the fiber port and connect optical fibers with LC-type or MPO-type connectors to the transceiver module.

Fiber connectors are indispensable passive components in an optical fiber communication system. They allow the removable connection between optical channels, which makes the optical system debugging and maintenance more convenient and the transit dispatching of the system more flexible. For more information, see H3C CR16000-M Routers Hardware Information and Specifications.

Installing a transceiver module and connecting optical fibers

To connect your router to the network through an optical fiber:

1.     Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. For more information, see "Attaching an ESD wrist strap" in "Installing removable components."

2.     Remove the dust plug from the target fiber port.

3.     Unpack the transceiver module.

4.     Pivot the clasp of the transceiver module up. Holding two sides of the transceiver module, gently push the module into the slot until you feel that the bottom spring tab catch in the slot.

Transceiver modules and fiber ports have disorientation rejection designs. If you cannot insert a transceiver module easily into a port, the orientation might be wrong. Remove and reorient the transceiver module.

In case of limited space, you can gently push against the front face of the transceiver module instead of the two sides.

5.     Remove the dust covers of the optical fiber connectors, and clean both ends of the optical fiber.

6.     Connect the optical fiber to the transceiver module.

¡     LC connector—Align the connector with the transceiver module and push it into the transceiver module slightly until it clicks into the place. See Figure5-1.

¡     MPO connector—Orient the connector with the white spot on it facing right. Insert the MPO fiber connector horizontally into the transceiver module. Push the MPO fiber connector into the transceiver module slightly until it clicks into the place. See Figure5-2.

7.     Use cable ties to bind optical fibers every 150 mm (5.91 in).

8.     Affix cable labels to the optical fiber to each end of the optical fiber.

Connecting an E1 cable

1.     Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

For more information, see "Attaching an ESD wrist strap" in "Installing removable components."

2.     Connect the HM96 connector of the E1 cable to the interface on the subcard and use a screwdriver to fasten the screws on the connector.

3.     Connect the other end of the E1 cable to the peer device.
