Juniper QFX10016, Hardware Manual

Page: 116 / 439

Overview
The line cards in QFX10000 modular switches combine a Packet Forwarding Engine and Ethernet
interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that can be installed in the
line card slots on the front of the switch chassis. The line cards are hot-insertable and hot-removable;
you can remove and replace them without powering off the switch or disrupting switch functions. See
Figure 52 on page 105 .

Network ports
Each QSFP28 socket can be configured to support:
• 100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver is inserted into
the ports marked with a fine black line underneath the socket and the port is configured for 100-
Gigabit Ethernet, the two adjacent ports are disabled and the QSFP28 socket is enabled for 100-
Gigabit Ethernet.
• 40-Gigabit Ethernet using QSFP+ optical transceivers.
• 10-Gigabit Ethernet using breakout cabling and attached optical transceivers. When configured for
channelization, the system converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit
Ethernet ports.
Any of the 36 ports 0 through 35 can be configured as either uplink or access ports.
Switch Ports
Each of the 12 QSFP28 ports supports:
• 100-Gigabit Ethernet QSFP28 transceivers
• 40-Gigabit Ethernet QSFP+ transceivers
• QSFP28 direct attach copper (DAC) cables
• QSFP+ DAC cables
