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 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 front panel contains light emitting diodes (LEDs) that indicate the
status of port links, power supplies, fans, stacking, and the overall system
status.
For information about the status that the LEDs indicate, see the User’s
Configuration Guide.
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 illuminated, and the unit number is displayed.
