The switch includes a variety of external port options. Fixed ports, such as the
RJ-45 management port, can be connected directly by attaching the appropriate
cable. Modular ports, such as Small Form-factor Pluggable Plus (SFP+) and Quad
Small Form-factor Pluggable Plus (QSFP+) ports, require the installation of a
transceiver module before the cable can be attached. This section covers each
supported port type separately:
 "The Serial Console Port" on page 21
 "The RJ-45 Management Port" on page 22
 "SFP+ Ports" on page 24
Notes:
 The illustrations in this document might differ slightly from your hardware.
 While the information in this section describes the 10 Gigabit Ethernet (GbE)
SFP+ transceiver module, it also applies to the 1 GbE SFP transceiver module.
 The switch supports MSA-compliant copper DACs, up to 5 m (16.5 ft.) in length.
To use the serial console, connect a serial cable to the RS-232 serial console port of
the switch and the other end of the cable to the console device.
Note: You must use one of the two cables in the Serial Access Cable option.
If your console device uses a standard RS-232 DB9 connector, attach the included
mini-USB-to-DB9 serial cable. Otherwise, if your console device uses an RJ-45
connector, attach the included mini-USB-to-RJ-45 serial cable and a user-supplied
RJ-45 adapter cable. Your adapter cable depends on the pin out required by your
console device. Pin out of the mini-USB-to-RJ-45 cable is as follows:
