Universal Serial Bus Ports; Connector Pin Assignments; Rj-45 Connector Pin Assignments For Poe Switches - Avaya 4900 Series Installing

Universal Serial Bus ports

The switches feature a Universal Serial Bus (USB) port on the front panel. Switch administrators can
use the USB port to perform tasks, previously performed through Trivial File Transfer Protocol
(TFTP), with a USB Mass Storage Device (for example, a flash drive or thumb drive):
• download software
• generate and download the ASCII configuration file
• generate and download the binary configuration file
The storage capacity of the USB device in use limits file and system operations.
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 cannot operate
with the switch. Only FAT or FAT32 file systems are currently supported; USB drives with NTFS file
systems are not supported. Consult the documentation provided with the USB drive to ensure
compliance with these standards.
