Universal Serial Bus (USB) ports
The Nortel Ethernet Routing Switch 4500 Series switches feature a USB
port on the left side of the front panel. Switch administrators can use the
USB port to perform tasks, previously performed through TFTP, with a USB
Mass Storage Device (for example, a flash drive or thumb drive):
•
download software
•
back up the syslog
•
generate and download the ASCII configuration file
File and system operations are limited by the storage capacity of the USB
device in use.
Support is available only for USB drives that comply with the Mass Storage
subsection of the USB 1.1 and USB 2.0 specification. Support does not
extend to third-party devices that do not comply with these standards.
Off-the-shelf drives that do not comply with these standards may not operate
with the switch. Consult the documentation provided with the USB drive to
ensure compliance with these standards.
