Dell Networking N4000 Series Configuration Manual page 105

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 RJ45
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 CLI only supports changing the speed.
The defaults are 9600 baud rate, 8 data bits, No Parity, 1 Stop Bit, No Flow
Control.
Out-of-Band Management Port
The Out-of-Band (OOB) management port is a 10/100/1000BASE-T
Ethernet port dedicated to remote switch management. Traffic on this port is
segregated from operational network traffic on the switch ports and cannot be
switched or routed to or from the operational network.
USB Port
The Type-A, female USB port supports a USB 2.0-compliant flash memory
drive. The Dell Networking switch can read or write to a flash drive with a
single partition formatted as FAT-32. You can use a USB flash drive to copy
switch configuration files and images between the USB flash drive and the
switch. You can also use the USB flash drive 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 attached 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 allows you to perform 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.
