112 Hardware Overview
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 "LED Definitions" on page 114 for more information.
Stack Master LED and Stack Number Display
When a switch within a stack is the master unit, the Stack Master LED is
solid green. If the Stack Master 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 Stack Master LED is illuminated, and the unit number is
displayed.
Back Panel
