Troubleshooting Troubleshooting with the Maintenance Bus (I C Bus) The I C bus (referred to as the “I squared C bus”) is a small internal maintenance bus used to monitor system conditions scanned by the power control module, write the fault display, store error state, and track configuration information in the system.
Page 84: Monitoring System Conditions
Troubleshooting Monitoring System Conditions The I C bus monitors the state of system conditions scanned by the PCM. There are two registers on the PCM: One records the state of the fans and power supplies and is latched when there is a fault. The other causes an interrupt on the I C bus when a CPU or system fan fails, an over- temperature condition exists, or power supplied to the system is out of tolerance.

Page 113: Error Registers
Error Detection with Error Registers Error Registers The DIGITAL Server 7300/7300R include registers that hold error information that you can use for troubleshooting. These registers include: • External Interface Status Register – EI_STAT • External Interface Address Register - EI_ADDR •...
Page 114 Error Detection with Error Registers External Interface Status Register – EI_STAT The EI_STAT register is a read-only register that is unlocked and cleared by any PALcode read. Subject to some restrictions, a read of EI_STAT also unlocks the EL_ADDR, BC_TAG_ADDR, and FILL_SYN registers. EI_STAT is not unlocked or cleared by reset.
Page 115 Error Detection with Error Registers Fill data from B-cache or main memory can have correctable or non-correctable errors in ECC mode. In parity mode, fill data parity errors are treated as non-correctable hard errors. System address/command parity errors are always treated as non-correctable hard errors, irrespective of the mode.

However, if the software is known to be good and the hardware is suspected, swap the IOD. PCI Master Abort Step 7 Master aborts normally occur when the operating system is sizing the PCI bus.
Page 134: Broken Memory
Error Detection with Error Registers Broken Memory Step 10 Refer to the following sections. For a Read Data Substitute Error (Non-Correctable ECC Error) When a read data substitute (RDS) error occurs, determine which memory module pair caused the error as follows: 1.
Page 135: Table 5-13 Ecc Syndrome Bits Table
Error Detection with Error Registers 3. When you have isolated the failing memory pair, determine which of the two modules is bad. (You cannot do this if the operating system is Windows NT.) Read the CPU FIL SYNDROME Register. If this register is non-zero, use the ECC syndrome bits in Table 5-13 to determine which module had the single-bit error.

Page 238 Operating the System Remotely Command Conventions • The commands are not case sensitive. • A command must be entered in full. • If a command is entered that is not valid, the command fails with the message: *** ERROR - unknown command *** Enter a valid command.
Page 239 Operating the System Remotely alert_clr The alert_clr command clears an alert condition within the RCM. The alert enable condition remains active, and the RCM will again enter the alert condition when it detects a system power failure. RCM>alert_clr alert_dis The alert_dis command disables RCM dial-out capability. It also clears any outstanding alerts.
Page 240 Operating the System Remotely disable The disable command disables remote access to the RCM modem port. RCM>disable The module’s remote access default state is DISABLED. The modem enable state is nonvolatile. When the modem is disabled, it remains disabled until the enable command is issued.
Page 241 Operating the System Remotely halt The halt command attempts to halt the managed system. It is functionally equivalent to pressing the Halt button on the system operator control panel to the “in” position and then releasing it to the “out” position. The RCM console firmware exits command mode and reconnects the user’s terminal to the server’s COM1 serial port.

Page 245: Dial-Out Alerts
Operating the System Remotely Dial-Out Alerts The RCM can be configured to automatically dial out through the modem (usually to a paging service) when it detects a power failure within the system. When a dial-out alert is triggered, the RCM initializes the modem for dial-out, sends the dial-out string, hangs up the modem, and reconfigures the modem for dial-in.
Page 246 Operating the System Remotely Enabling the Dial-Out Alert Function: 1. Enter the set rcm_dialout command, followed by a dial-out alert string, from the SRM console (see in Error! Reference source not found.). 2. The string is a modem dial-out character string, not to exceed 47 characters, that is used by the RCM when dialing out through the modem.
Page 247 Operating the System Remotely Composing a Modem Dial-Out String The modem dial-out string emulates a user dialing an automatic paging service. Typically, the user dials the pager phone number, waits for a tone, and then enters a series of numbers. The RCM dial-out string (Example 9-5) has the following requirements: •...
