							Expanded Operating TemperatureNOTE: When operating in the expanded temperature range, system performance may be impacted.
NOTE: When operating in the expanded temperature range, ambient temperature warnings may be reported on 
the LCD and in the System Event Log.
< 10% of annual operating hours5 °C to 40 °C at 5% to 85% RH with 26 °C dew point.
NOTE: Outside the standard operating temperature 
(10 °C to 35 °C), the system can operate down to 5 °C 
or up to 40 °C for a maximum of 10% of its annual 
operating hours.
For temperatures between 35 °C and 40 °C, de-rate 
maximum allowable dry bulb temperature by 1 °C per 175 
m above 950 m (1 °F per 319 ft).
< 1% of annual operating hours–5 °C to 45 °C at 5% to 90% RH with 26 °C dew point.
NOTE: Outside the standard operating temperature 
(10 °C to 35 °C), the system can operate down to –5 
°C or up to 45 °C for a maximum of 1% of its annual  operating hours.
For temperatures between 40 °C and 45 °C, de-rate 
maximum allowable dry bulb temperature by 1 °C per 125 
m above 950 m (1 °F per 228 ft).
Expanded Operating Temperature Restrictions•Do not perform a cold startup below 5 °C.
•Allow processor performance degrade.

°F/228 ft) above 950 m (3,117 ft).Particulate Contamination
NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from particulates and 
gaseous contamination. If it is determined that levels of particulates or gaseous pollution are beyond the limits 
specified below and are the reason for the damage and/or failures to your equipment, it may be necessary for you 
to re-mediate the environmental conditions that are causing the damage and/or failures. Re-mediation of  environmental conditions will be the responsibility of the customer.
Air Filtration
NOTE: Applies to data center environments only. Air 
filtration requirements do not apply to IT equipment 
designed to be used outside a data center, in 
environments such as an office or factory floor.
Data center air filtration as defined by ISO Class 8 per 
ISO 14644-1 with a 95% upper confidence limit.
NOTE: Air entering the data center must have 
MERV11 or MERV13 filtration.
Conductive Dust
NOTE: Applies to data center and non-data center 
environments.
Air must be free of conductive dust, zinc whiskers, or  other conductive particles.Corrosive Dust•Air must be free of corrosive dust.124 
						

							EnvironmentalNOTE: Applies to data center and non-data center 
environments.•Residual dust present in the air must have a 
deliquescent point less than 60% relative humidity.Gaseous ContaminationNOTE: Maximum corrosive contaminant levels measured at  ≤50% relative humidity.Copper Coupon Corrosion Rate

System Messages
LCD Messages
NOTE: Applicable only if your system has an LCD display.
The LCD messages consist of brief text messages that refer to events recorded in the System Event Log (SEL). For information on the SEL and configuring system management settings, see the systems management software 
documentation.
NOTE: If your system fails to boot, press the System ID button for at least 5 seconds until an error code is displayed 
on the LCD. Record the code, then see System Error Messages.
Viewing LCD Messages
If a system error occurs, the LCD screen will turn amber. Press the Select button to view the list of errors or status  messages. Use the Left and Right buttons to highlight an error number, and press the Select button to view the error.
Removing LCD 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 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.
•Power cycle — Turn off the system and disconnect it from the electrical outlet; wait approximately 10 seconds, reconnect the power cable, and restart the system.
System Error Messages
System messages appear on the monitor to notify you of a possible problem with the system. These messages refer to 
events recorded in the System Event Log (SEL). For information on the SEL and configuring system management settings, 
see the systems management software documentation.
Some messages are also displayed in an abbreviated form on the system's LCD, if the system includes that feature.
NOTE: The LCD error messages listed here are displayed in the simple format. See Setup Menu to select the format 
in which the messages are displayed.
NOTE: If you receive a system message not listed here, check the documentation of the application that was 
running when the message was displayed or the operating system's documentation for an explanation of the 
message and recommended action.
NOTE: In some messages, a particular system component is identified by name (“”) component number 
(“”), or location (“bay”).
