Table 2 (Page 3 of 3). Ethernet controller messages Error Code Description M96 Cannot ARP MTFTP address. M98 Cannot open MTFTP connection. M99 Cannot read from MTFTP connection. Txx If you are running a TFTP session to another computer, an error message generated by the TFTP session will contain a message prefix of Txx. Light path diagnostics The light path diagnostics built into the server allow you to quickly identify the type of system error that occurred. The server is designed so that any LEDs that are illuminated remain illuminated when the server shuts down as long as the ac power source is good and the power supplies can supply +5V dc current to the server. This feature helps you isolate the problem if an error causes the server to shut down. The light path diagnostics begin with the System Error LED on the information LED panel. (See the illustration in "Information LED panel" on page 205.) When this light is illuminated, use the following information to isolate the problem. If the System Error LED on the information LED panel on the front of the server is on, a system error was detected. Check to see which of the LEDs on the diagnostics panel inside the server are on. - Diagnostics panel LEDs off Error log is 75% full or more. Action: PFA alert logged. Check System Error Log for additional information. - SMI LED on A systems management event occurred. Action: Restart the server. If the problem persists, go to "General checkout" on page 8. Check System Error Log for additional information. - NMI LED on A non-maskable interrupt occurred. The PCI 1 or PCI 2 LED will probably also be on. Actions: 48 Netfinity Server HMM
