Finding and helping you fix the most common network error conditions (for example, faulty network cabling,
and nonstandard network topologies).
•
Informing you of the problem with clear, easy-to-understand messages.
•
Recommending network configuration changes to enhance the performance of your network.
The following interfaces provide tests, indicators, and an event log that can be used to monitor the switch and its
network connections and to help you take advantage of these proactive networking features:
•
Aruba AirWave: A powerful and easy-to-use network operations system that manages wired and wireless
infrastructures.
•
IMC (Intelligent Management Center): an SNMP-based network management tool that is included with your
switch. Free trials of IMC can be downloaded at http://www.hpe.com/networking/imc
•
A graphical web browser interface that you can use to manage your switch from a PC running a supported
web browser, for example Microsoft Internet Explorer and Firefox.
•
A full-featured easy-to-use console interface that you can access by connecting a standard terminal or PC
running a terminal emulator to the switch's console port using an Aruba X2C2 RJ45 to DB9 Console Cable
(JL448A) (sold separately). The console command line interface is also accessible through a Telnet or SSH
connection.
Hardware diagnostic tests
Testing the switch by resetting it
If you believe the switch is not operating correctly, you can reset the switch to test its circuitry and operating code.
To reset a switch, try any of the following:
•
Unplug and plug in the power cord (power cycling).
•
Press the Reset button on the front of the switch.
•
Reboot the switch via the management console's boot system command.
Power cycling the switch and pressing the Reset button both cause the switch to perform its power-on self test,
which almost always will resolve any temporary operational problems. These reset processes also cause any
network traffic counters to be reset to zero, and cause the System Up Time timer to reset to zero.
Checking the switch LEDs
See Diagnosing with the LEDs on page 50 for information on interpreting the LED patterns and LED behaviors.
Checking console messages
Useful diagnostic messages may be displayed on the console screen when you reset a switch. Connect a PC
running a VT-100 terminal emulator program or a standard VT-100 terminal to the switch's console port and
configure it to run at 9600 baud, and with the other terminal communication settings shown in Terminal
configuration on page 38.
When you reset the switch, note the messages that are displayed. Additionally, you can check the switch event
log, which can be accessed from the console using the show log command, or from the console main menu.
