or remotely using Telnet or Secure Shell.
Remote access with SNMPv1, v2c, or v3.

Chapter 1: Overview
18
Management
Panel
The management panel has the following features:
Console RS-232 port for local management (no IP address
required).
USB 2.0 port for storing backup copies of system configuration
files, updating management software, and other management
functions.
An eco-friendly button for turning off the port and system LEDs to
reduce power consumption.
Note
The x950-52XSQ and x950-52XTQm switches do not have the
eco-friendly button; however, the eco-friendly mode can be turned
on or off with the ECOFRIENDLY LED or NO ECOFRIENDLY LED
command in the Command Line Interface.
Network management port for initial configuration and
maintenance access to the chassis.
Power Supplies The switch has slots for two power supplies on the back panel. The switch
