HP Integrated Lights-Out 2 User Guide

• The use of the diagnostic port is automatically sensed when an active network cable is plugged in toit. When switching between the diagnostic and back ports, allow one minute for the networkswitchover to be complete before attempting to connect through the web browser.• If a critical activity is in progress, the diagnostic port cannot be used until the critical activity iscomplete. Critical activities include the following:• Firmware upgrade• Remote Console session• SSL initialization• If you are using a client workstation that contains more than one enabled NIC, such as a wirelesscard and a network card, a routing issue might prevent you from accessing the diagnostic port. Toresolve this issue:1. Have only one active NIC on the client workstation. For example, disable the wireless network card.2. Configure the IP address of the client workstation network to match the iLO 2 Diagnostic Portnetwork so that the following conditions are met:• The IP address setting is 192.168.1.X, where X is any number other than 1, because the IPaddress of the diagnostic port is set at 192.168.1.1.• The subnet mask setting is 255.255.255.0.Inability to connect to the iLO 2 processor through the NICIf you cannot connect to the iLO 2 processor through the NIC, try any or all of the followingtroubleshooting methods:• Confirm that the green LED indicator (link status) on the iLO 2 RJ-45 connector is on. This conditionindicates a good connection between the PCI NIC and the network hub.• Look for intermittent flashes of the green LED indicator, which indicates normal network traffic.• Run the iLO 2 RBSU to confirm that the NIC is enabled and verify the assigned IP address andsubnet mask.• Run the iLO 2 RBSU and use the F1-Advanced tab inside of the DNS/DHCP page to see the status ofDHCP requests.• Ping the IP address of the NIC from a separate network workstation.• Attempt to connect with browser software by entering the IP address of the NIC as the URL. You cansee the iLO 2 Home page from this address.• Reset iLO 2.NOTE: If a network connection is established, you may have to wait up to 90 seconds for the DHCP serverrequest.ProLiant BL p-Class servers have a Diagnostic Port available. Connecting a live network cable to thediagnostic port causes iLO 2 to automatically switch from the iLO 2 port to the diagnostic port. Whenswitching between the diagnostic and back ports, allow one minute for the network switchover to becomplete before attempting connection through the browser.Inability to log in to iLO 2 after installing the iLO 2 certificateIf the iLO 2 self-signed certificate is installed permanently into some browsers and the iLO 2 is reset, youmight not be able to log back in to iLO 2 because iLO 2 generates a new self-signed certificate every timeit is reset. When a certificate is installed in the browser, it is indexed by the name contained in thecertificate. This name is unique to each iLO 2. Every time iLO 2 resets, it generates a new certificate withthe same name.Troubleshooting iLO 2 159
