Diagnostic Tests
The HP Stack Manager software provides tests and indicators that can
be used to monitor the hub and its network connections. See chapter 2,
“Installing and Using HP Stack Manager”, and the software’s online Help
system for more details about these tests and indicators.
Testing the Hub Only
If you believe that the hub is not operating correctly, you can test the
hub’s circuitry by resetting the hub through one of these procedures:
Press the Reset button.
Select the “Power-on Reset” option from HP Stack Manager’s Reset
function or select type the REset command using the ASCII console.
Select the “Power-on Reset” option from the HP Interconnect
Manager interface.
Each of these procedures will cause the hub to complete its power-on
self-test. If any error conditions exist in the hub, the LEDs should
display the condition. See “Diagnosing with the LEDs” earlier in this
chapter to interpret the LED display.
Testing the Hub’s Ports and the Links
These tests are available only on hubs that have an HP Ethernet SNMP
Module installed.
To test the hub’s ports and the attached network links, choose one of the
following ways to run a test between the hub and an addressable device
connected at the remote end of each of the cables you wish to test:
Select Link Test from HP Stack Manager’s Network Test function.
This causes the hub to send IEEE 802.2 Test command packets to a
specified network device. The device must be able to send an IEEE
802.2 Test response packet upon receipt of a Test command packet.
You specify the remote device by its 12-digit hexadecimal station
address.
