174 Hardware Overview
Console Port
The console port provides serial communication capabilities, which allows
communication using RS-232 protocol. The serial port provides a direct
connection to the switch and allows access to the CLI from a console
terminal connected to the port through the provided serial cable (with RJ-45
YOST to female DB-9 connectors).
The console port is separately configurable and can be run as an asynchronous
link from 1200 baud to 115,200 baud. The Dell EMC CLI only supports
changing the speed. The defaults are 115,200 baud, 8 data bits, no parity, 1
stop bit, and no flow control.
USB Port
The Type-A female USB port supports a USB 2.0-compliant flash memory
drive. The Dell EMC Networking N-Series switch can read or write to a flash
drive with a single partition formatted as FAT-32. Use a USB flash drive to
copy switch configuration files and images between the USB flash drive and
the switch. The USB flash drive may be used to move and copy configuration
files and images from one switch to other switches in the network. The
system does not support the deletion of files on USB flash drives.
The USB port does not support any other type of USB device.
Reset Button
The reset button is accessed through the pinhole and enables performing a
hard reset on the switch. To use the reset button, insert an unbent paper clip
or similar tool into the pinhole. When the switch completes the boot process
after the reset, it resumes operation with the most recently saved
configuration. Any changes made to the running configuration that were not
saved to the startup configuration prior to the reset are lost.
Port and System LEDs
The front panel contains light emitting diodes (LEDs) that indicate the
status of port links, power supplies, fans, stacking, and the overall system
status. See "N3100-ON Series LED Definitions" on page 175 for more
information.
