Console Port
The console port provides serial communication capabilities, which allows communication using the RS-232 protocol. The serial port
provides a direct connection to the switch and allows access to the command line interface (CLI) from a console terminal connected to
the port through the provided serial cable.
The console port is separately configurable and can run as an asynchronous link from 1,200 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.
USB Port
The Type-A, female USB port supports a universal serial bus (USB) 2.0-compliant flash memory drive. The Dell Networking switch can
read or write to a flash drive 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 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.
Port and System LEDs
The I/O-side contains LED that indicate the status of port links, power supplies, fans, stacking, and the overall system status.
Stack Master LED and Stack Number Display
When a switch within a stack is the master unit, the stack master LED, which is labeled M, is solid green. If the M LED is off, the stack
member is not the master unit. The Stack No. panel displays the unit number for the stack member. If a switch is not part of a stack (in
other words, it is a stack of one switch), the M LED is lit, and the unit number displays.
