Connecting to the HP D2D from the backup application

Make sure you have the latest version or software patches for the backup application. Please see
http://www.hp.com/go/connect
Stop and restart the backup application services after the backup device has been discovered. If you
still cannot see the device, check Device Manager to make sure it is accessible from the host.
• Make sure that the iSCSI initiator is connected to the devices and log on to them, if they are not,
see "Targets
• If it is not accessible, rerun Discovery.

Connecting to the network

If you cannot see your device on the network, please check the following:
1. Regardless of the network configuration mode and interface type, please ensure that there is a
CAT-5E (or above) Ethernet cable connected to network port 1. This is the primary port for com-
munication to the Web Management Interface and on SCSI models, the primary port for data
communications.
2. Check that the LEDs are flashing on the LAN Port 1 connector and on the LAN Port 1 LED on the
front panel. (See also
