RackSwitch G8264T: Installation Guide
QSFP+ ports enable you to make one 40GbE connection, or four 10 GbE
connections, using a breakout cable, as follows:
• QSFP+ optical transceiver with MTP-to 4 LC (SFP+) fiber breakout cables.
This option supports only BLADE 10GBASE-SR SFP+ transceivers. The
40GBASE-SR4 specification (802.3ba-2010) indicates a higher optical power
level than standard 10GBASE-SR. BLADE SFP+ SR transceivers can handle the
higher optical power levels.
• QSFP+ to four GbE SFP+ breakout DAC. The SFP+ connectors on supported
breakout DACs are labelled A, B, C, and D, which correspond to the first, second,
third, and fourth ports in the port range.
RJ-45 management port
The 10/100/1000BaseT management port (RJ-45) is located on the front panel.
These management ports support in-line management and Control Plane Stacking.
The following table describes the RJ-45 connector pin assignments.
USB port
The USB port enables you to connect a USB drive to the switch. You can copy files
from the switch to the USB drive, or from the USB drive to the switch. You also can
start the switch using files on the USB drive.
For more information about using the USB drive, see the RackSwitch G8264T
