Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 25)

E13F8 HOST TO PCI BUS
E13F8 MEM CONTROLLER Faulty or improperly installed
memory module; faulty system
board.
Ensure that the memory modules are
properly installed. If the problem
persists, replace the faulty memory
module(s) (see " Memory Modules ").
If the problem persists, replace the
system board (see " System Board ").
E1580 POWER CONTROL Faulty system board. Replace the system board (see
" System Board ").
E20F1 OS HANG Operating system watchdog timer
timed out.
Restart your system. If the problem
persists, see your operating system
documentation.
EFFF0 RAC ERROR Remote access controller firmware
failure; faulty system board.
Replace the expansion-card riser
board (see " Expansion-Card Riser
Board ").
EFFF1 POST ERROR BIOS error. Update the BIOS firmware. Download
the latest firmware from the
Dell | Support website at
support.dell.com.
EFFF2 BP ERROR Faulty or improperly installed
backplane board.
Ensure that the interface cables are
securely connected to the SCSI
backplane board. If the problem
persists, replace the backplane board
(see " SCSI Backplane Board ").
Solving Problems Described by LCD Status Messages
When a single message appears on the status LCD, locate the code in Table 3-9 and perform the suggested corrective action.
The code on the LCD can often specify a very precise fault condition that is easily corrected. For example, if the code
E0280 MISSING VRM 2
appears, you know that a microprocessor is installed in socket 2, but the VRM for that microprocessor
is either improperly installed or missing.
In contrast, you might be able to determine the problem if multiple related errors occur. For example, if you receive a series
of messages indicating multiple voltage faults, you might determine that the problem is a failing power supply.
Removing LCD Status Messages
For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is automatically removed
when that sensor returns to a normal state. For example, if temperature for a component goes out of range, the LCD displays
the fault; when the temperature returns to the acceptable range, the message is removed from the LCD. For other faults, you
must take action to remove the message from the display:
Clear the SEL — You can perform this task remotely, but you will lose the event history for the system.
Chassis intrusion — When you remove the cover, the system assumes that you are servicing the bad component; the
LCD clears when you replace the cover.
Power cycle — Turn off the system and disconnect it from the electrical outlet; wait approximately ten seconds,
reconnect the power cable, and restart the system.
Any of these actions will remove fault messages, and return the status indicators and LCD colors to the normal state.
Messages will reappear under the following conditions:
The sensor returns to a normal state but fails again, resulting in a new SEL entry.
The system is reset and new error events are detected.
A failure is recorded from another source that maps to the same display entry.
