USB Port
The Type-A, female USB port supports a USB 2.0-compliant flash memory
drive. The N4000 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. Deletion of files on
the USB drive is not supported.
The USB port does not support any other type of USB device.
Port and System LEDs
The front panel contains light emitting diodes (LEDs) to indicate port status.
For information about the status that the LEDs indicate, see "LED
Definitions" on page 121.
SFP+ and QSFP+ Ports
SFP+ and QSFP+ ports support Dell-qualified transceivers. The default
behavior is to log a message and generate an SNMP trap on insertion or
removal of an optic that is not qualified by Dell. This message and trap can be
suppressed by using the service unsupported-transceiver command.
N4000 Back Panel
The N4000 series back panel has the following features:
•Console port
• Out-of-band management port
