USB port
The USB 2.0 port can be used with a USB memory stick to upgrade firmware, back up the
configuration files or transfer Syslog Files. Live access to the switch configuration and diag-
nostics is only provided through the console port or an Ethernet connection using one of the
28 ports. The USB port does not provide PC access to switch configuration and diagnostic
information.
The reset button in the power supply LED area restarts the switch if pressed for less than
2 s. If pressed for more than 2 s in conjunction with secure console commands restores the
switch to the factory default configuration and IP address.

tions. These slots also support IEE1588-based Precision Time Protocol (PTP) timing sig-
nals
Port/Line module 4
1 Gigabit/10 Gigabit slot accepts a four-port module, typically used for network trunk up-
links, but can also be used for added device connections This slot does NOT support IEEE

ronmental contamination and unauthorized access to slot connectors. It may be in-
stalled over slots 1-4.
