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 23
 "The RJ‐45 Management Port" on page 24
 "SFP+ Ports" on page 26
 "QSFP+ Ports" on page 29
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:
