Heater Solution

Heater Solution Summary

XR8000 needs to support an operating temperature range of ‐20°C to 65°C with a non‐operational range of ‐40°C to 65°C. The following major components do not support an industrial range and may need to be heated before they can be powered on:

Intel Xeon‐SP SPR CPU – minimum temperature is 0°C.
Intel Emmitsburg PCH south bridge – minimum temperature is 0°C.
iDRAC temperature range of 0°C to 70°C
CPLD temperature range of 0°C to 85°C
DIMM memory – minimum temperature is 0°C.
M.2 drives – temperature range is 85°C with selected range of 0°C to 85°C.
Adapter cards – temperature ranges vary depending on the manufacturer.

NOTE:Only XR8620t supports Heater Solution configuration.

NOTE:After pressing the power button, it takes approximately 5.5 minutes for the heater to warm the system from -20°C to 5°C before the power is applied to initiate system startup.

NOTE:Heater Manger is tested to -20°C.

NOTE:The heater Manager will monitor and maintain each heater zone's temperature while system is on.

NOTE:Jumper cables should be installed in XR8620t heater solution configuration only. Jumper cables are to be installed only when there is no heater module installed in the system, and since the heater slots on 2U PDB continue to provide power in the absence of heater module, or jumper cables, it can cause a short circuit.

NOTE:The jumper cables from heater slots 8,9 and 10 have to be transferred to the new PDB if the current PDB is being replaced and if the heater is not installed on the new PDB. The jumper cables are to be installed in heater 8, heater 9 and heater 10 slots on 2U PDB. For more details, see installing the jumper cables.

Sub-System details

In cold environments components need to be heated to an operational temperature range before they can be powered up. A small industrial range microcontroller that is called the heater manager is needed to measure the temperature by strategically placed temperature sensors and to apply current to one or more heating pads.

System heating is separated into a maximum of ten zones for different parts of the system. Each zone has one or more heating pads (connected in parallel) and one or more temperature sensors. Each zone can have a different minimum temperature but in general they are all the same and above 0C. The below table shows a potential list of heater modules in the Dell PowerEdge XR8000. Heaters in the top U connect to the 2U_PDB for easy serviceability.

Once the heater manager has power, it turns on the green heater LED (HM_SYS_PH_LED_N) and determines the temperature of each zone. Any zone below the threshold (for example, 4°C) will have its heater turned on until the zone is up to temperature. The heater manager should continue to monitor the temperature and turn on the heater pad if the temperature ever drops below a threshold (for example, 2°C). If no heating is required because the system is already above the heating thresholds, then the LED should still be flashed briefly for visible feedback that the system is in fact starting up. A jumper can be used to power the system without heating.

The image shows the iDRAC interface for heater manager — Figure 1. iDRAC interface for Heater Manager

NOTE:Be advised not to rely on the heat duration data for your assessment, as this information will be excluded in the upcoming iDRAC release.

NOTE:See Table - Zone Definition and Location in the next topic for Zone details.

Monitoring is added in each zone to ensure that the heating pad is present. A blinking amber heater LED (HM_SYSTEM_PH_FAULT_LED_N) indicates a problem with the heating sub‐system. This flashing LED is the only indication of a problem because iDRAC is not yet available for problem logging. Any failure in the heating system, flashes the amber heater status LED, and initiates a system shutdown if the temperature starts to drop below the temperature threshold. If the ambient temperature is high enough (for example, 10°C), then the iDRAC and shared NIC is powered to ensure that the problem is logged with iDRAC and is available on a remote iDRAC console.

NOTE: All heater modules for XR8620t should be at the point of sale.

NOTE:No APOS Cust kit for heater modules is available. The XR8620t heater module (ET) involves complex hardware connections, including thermal/heater pad/sensors, etc. Due to this complexity, it is not easy for customers to modify the configuration after shipment or change any M.2s connected to ROR-N1.

Troubleshooting- Heater Manager

Heater Manager Error Check Allocation

Step 1: Heater Error LED

LED lights Green when system pre‐heating is enabled and will turn off when system pre‐heating is completed. The heater manager will continue to maintain the proper temperature on the system after preheating, but the LED will stay off while the system is on.
LED flashes Amber with one blink per second frequency when any required heater or thermal sensor is absent or has failed.

Step 2: Check the iDRAC Life Cycle Log:

The Lifecycle log can be accessed via iDRAC GUI -> Maintenance -> Lifecycle Log.

Environmental Requirements for installing XR8000

A proper installation of XR8000 protects the system and its components from damage that is caused by external environmental conditions. So, to ensure normal operation and avoid any unplanned downtime and maintenance activity it is highly imperative that there is a proper planning and preparation of the site before installing the XR8000 . Also, it is to be noted that the same site sanity must be maintained during the entire life cycle of the XR8000 server to ensure smooth operations.

General guidelines for maintaining the XR8000:

It is recommended to keep the system from heat sources and obstructions blocking the airflow.
It is recommended not to allow spillage of liquid into the system and not to operate when the system is wet.
If there are any openings in the system, it is recommended not to insert any objects into those points.
It is highly advised not to tamper and modify any power cables or PSUs as it could potentially damage the systems.

Site Planning Recommendation:

The site should have proper cooling facilities to take care of the operating temperature range of the server.
The rack or cabinet where the server is going to be installed should have adequate space for cable routing.
The Rack or cabinet should have enough strength to hold the weight of the server.
For Conductive dust, the air must be free of conductive dust, zinc whiskers, or other conductive particles. This protects the system from any contamination.
For corrosive dust, the air must be free from any corrosive dust and the Residual dust present in the air must have a deliquescent point less than 60% relative humidity. Note this condition applies for both data center and non-data center environments.
The system is best found to operate at -5C to 55C and for some conditions from -20C to 65C , so the site conditions could maintain the optimum operating condition.
For protection of the system from humidity it is expected to have an environment with a humidity percent range of 8% RH with -12°C minimum dew point to 80% RH with 21°C (69.8°F) maximum dew point.
For seismic zones , the maximum operating vibration is 0.21 G _rms at 5 Hz to 500 Hz (all operation orientations).

Particulate and gaseous contamination specifications

The following table defines the limitations that help avoid any equipment damage or failure from particulates and gaseous contamination. If the levels of particulates or gaseous pollution exceed the specified limitations and result in equipment damage or failure, you must rectify the environmental conditions. Remediation of environmental conditions is the responsibility of the customer.

Table 1. Particulate contamination specificationsAir filtration specification: Data center air filtration as defined by ISO Class 8 per ISO 14644-1 should have a 95% upper confidence limit. Note: This condition applies only to data center environments. 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. Note: Air entering the data center must have MERV11 or MERV13 filtration. Conductive dust specification: Air must be free of conductive dust, zinc whiskers, or other conductive particles. Note: This condition applies to data center and non-data center environments. Corrosive dust specification: Air must be free of corrosive dust. Residual dust present in the air must have a deliquescent point less than 60% relative humidity. Note: This condition applies to data center and non-data center environments.
