Communication troubleshooting Communications check NOTE: Communication problems are normally the customer's responsibility. Time spent attempting to resolve these problems might not be covered by the Hewlett-Packard warranty. Refer the customer to the network administrator for assistance in troubleshooting network problems. EIO troubleshooting The Jetdirect configuration page shown in figure 125 on page 230 contains valuable information about the current status of the EIO accessories. Before attempting to troubleshoot a network problem or notifying your network consultant of a problem, always print a configuration page. If an EIO accessory is installed, the Jetdirect configuration page also prints. See the HP Jetdirect Network Interface Configuration Guide for detailed explanations of network issues. Jetdirect configuration ● If the EIO Jetdirect print server has successfully turned on and completed its internal diagnostics, the I/O card ready message will display. If communication is lost, an I/O not ready message displays followed by a two digit error code. Consult the HP Jetdirect Network Interface Configuration Guide for further details and recommended action. ● The "Network Statistics" column indicates the status of network activity. Bad packets, framing errors, un-sendable packets, and collisions should be minimal. If a high percentage (greater than 1%) of these occur, contact the network administrator. All of the statistics are set to zero when the product is powered off. ● A "Novell Status" block should state the Novell printer server name to which the product is connected. If the Node Name reads "NPIxxxxxx" (xxxxxx = last six digits of the EIO LAN address), the EIO card has not been configured for a Novell server. This could indicate that the card is operating under an IPX protocol other than Novell. Consult with the network administrator if the Node Name is not present. ● In the TCP/IP protocol block, the default IP address is "192.0.0.192." It is acceptable to operate the product with this default address. The error message ARP DUPLICATE IP ADDRESS might appear in this block. This is also an acceptable error code if the TCP/IP protocol is not being used. Please check with the network administrator to determine the correct IP address for the product. Embedded LAN troubleshooting Although networking is integrated, the embedded LAN has additional features to assist in troubleshooting. These include the following features: ● The ability to turn on and turn off the embedded networking. ● An internal diagnostic to check the networking hardware. ● The ability to initiate communication from the product to other network devices to check communication paths. ● The ability to upgrade the embedded LAN separately from the product firmware. 394 Chapter 7 Solve problems ENWW
