9. By default the probe’s name is a random mix of letters and numbers. Change the name of the probe to

something meaningful to you. The name might be the physical location of the probe. Click

Apply

to save

your changes and close the window.

By default the GigaStor runs the Expert Probe as a Windows service and starts automatically at system
startup. This prevents you from using the Observer analyzer on the GigaStor. You must connect to the
GigaStor using Observer on a different system.

After completing this task:

Now that the probe’s name is configured, there are several other settings you will need to configure before you
connect the probe to an Observer analyzer. All probes share some common settings. There are also settings
unique to the type of probe you are using. All common and unique settings are described in

Configuring the

probe’s adapter speed, ToS/QoS precedence, and statistics sampling

Configuring the Lights out Management port for your GigaStor

Your probe comes with an on-board LOM port that provides you a dedicated management channel for device
maintenance. It allows you to monitor and manage your probe by remote control regardless of whether the
probe is powered on.

If you want to use the Lights out Management features, you must set the IP address for the LOM port in the
probe’s BIOS.

1. Ensure the Lights out Management port is connected to your network using a straight-through Ethernet

cable. A crossover cable will not work.

2. When starting your probe, press Delete during POST to enter the BIOS setup. If you are using a GigaStor, wait

for the RAID to initialize, which may take a moment.

3. In the BIOS, choose Server > IPMI Configuration. Change the IP address for LAN 3 to a static address that is a

valid and usable address on your network.

4. Press F10 to save your changes and to exit the BIOS setup. Restart your probe. The LOM port is now available

on the IP address you chose. The LOM card comes with its own processor that is separate from the probe.
Because of this, if the LOM card’s web interface does not come up after restarting the system, shut down the
probe and remove the power, then wait at least 10 seconds before starting the system. This resets the LOM
card and makes it visible on your network. Only the head unit needs to be shut down, any attached drive
units may stay running.

The default user name and password for the LOM card's web interface is either ADMIN/ADMIN. To change
the default password, open a web browser to http://
