Operations

Power up the server

About this task

HPE Cray XD2000 series chassis firmware will not initiate an automatic power-up sequence when the servers are installed. Use one of the following methods to power up each server:

Use a virtual power button selection through BMC.
Press and release the Power On/Standby button.

When the server goes from standby mode to full power mode, the server power LED changes from amber to green.

Power down the server

Before powering down the server for any upgrade or maintenance procedures, perform a backup of critical server data and programs.

IMPORTANT: When the server is in standby mode, auxiliary power is still being provided to the system.

To power down the server, use one of the following methods:

Press and release the Power On/Standby button.

This method initiates a controlled shutdown of applications and the OS before the server enters standby mode.
Press and hold the Power On/Standby button for more than 4 seconds to force the server to enter standby mode.

This method forces the server to enter standby mode without properly exiting applications and the OS. If an application stops responding, you can use this method to force a shutdown.
Use a virtual power button selection through BMC.

This method initiates a controlled remote shutdown of applications and the OS before the server enters standby mode.

Before proceeding, verify that the server is in standby mode by observing that the system power LED is amber.

Power capping

Server power capping is useful when you want to hold the actual used system power to a specific amount. This amount might be lower than what the system configuration might maximally use. The power capping feature in the HPE Cray XD2000 series chassis operates at the server enclosure (chassis) level.

Operational requirements

Site requirements

The server must be located in a computer room or server room. The room must:

Be only accessible to authorized technicians trained the room restriction reasons and precautions.
Be within an area that is ideally locked or at minimum not accessible to unauthorized personnel.

Space and airflow requirements

To allow for servicing and adequate airflow, observe the following space and airflow requirements when deciding where to install a rack:

Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or row of racks.

Hewlett Packard Enterprise servers draw in cool air through the front door and expel warm air through the rear door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the cabinet.

CAUTION: To prevent improper cooling and damage to the equipment, do not block the ventilation openings.

When vertical space in the rack is not filled by a server or rack component, the gaps between the components cause changes in airflow through the rack and across the servers. Cover all gaps with blanking panels to maintain proper airflow.

CAUTION: Always use blanking panels to fill empty vertical spaces in the rack. This arrangement ensures proper airflow. Using a rack without blanking panels results in improper cooling that can lead to thermal damage.

CAUTION: If a third-party rack is used, observe the following additional requirements to ensure adequate airflow and to prevent damage to the equipment:

Front and rear doors — If the 42U rack includes closing front and rear doors, you must allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64 percent open area for ventilation).
Side — The clearance between the installed rack component and the side panels of the rack must be a minimum of 7 cm (2.75 in).

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position the system in a well-ventilated, climate-controlled environment.

The maximum recommended ambient operating temperature (TMRA) for most server products is 35°C (95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F).

CAUTION: To reduce the risk of damage to the equipment when installing third-party options:

Do not permit optional equipment to impede airflow around the server or to increase the internal rack temperature beyond the maximum allowable limits.
Do not exceed the manufacturer’s TMRA.

Power requirements

Installation of this equipment must comply with local and regional electrical regulations governing the installation of IT equipment by licensed electricians. This equipment is designed to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, refer to the product rating label or the user documentation supplied with that option.

WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply branch circuit that provides power to the rack. Consult the electrical authority having jurisdiction over wiring and installation requirements of your facility.

CAUTION: Protect the server from power fluctuations and temporary interruptions with a regulating UPS. This device protects the hardware from damage caused by power surges and voltage spikes and keeps the server in operation during a power failure.

Grounding requirements

The building installation must provide a means of connection to protective earth.
The equipment must be connected to that means of connection.
A service person must check whether the socket-outlet from which the equipment is to be powered provides a connection to the building protective earth. If the outlet does not provide a connection, the service person must arrange for the installation of a protective earthing conductor from the separate protective earthing terminal to the protective earth wire in the building.

Device bay thermal requirements

Operate the chassis only when a device or blank is installed in all device bays. Before powering up the chassis, be sure to do the following:

Install a drive or drive blank into all drive bays.
Install a server or a blank into all server bays.
Install a power supply or power supply blank into all power supply bays.

Rack warnings and cautions

WARNING: To reduce the risk of personal injury or equipment damage when unloading a rack:

At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and might become unstable when being moved on its casters.

Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle the rack from both sides.

WARNING: When all components are removed, the system weighs 12.46 kg (27.47 lbs). When all components are installed, the system can weigh up to 48.3 kg (106.50 lb). Before configuring your rack solution, be sure to check the rack manufacturer weight limits and specifications. Failure to do so can result in physical injury or damage to the equipment and the facility.

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:

The rack has anti-tip measures in place. Such measures include floor-bolting, anti-tip feet, ballast, or a combination as specified by the rack manufacturer and applicable codes.

The leveling jacks (feet) are extended to the floor.

The full weight of the rack rests on the leveling jacks (feet).

The stabilizing feet are attached to the rack if it is a single-rack installation.

The racks are coupled together in multiple rack installations.

WARNING: The chassis is heavy. To reduce the risk of personal injury or damage to the equipment, do the following:

Observe local occupational health and safety requirements and guidelines for manual material handling.

Get help to lift and stabilize the product during installation or removal, especially when the product is not fastened to the rails. Recommends that a minimum of two people are required for all rack server installations. A third person may be required to help align the server if the server is installed higher than chest level.

Use caution when installing the server in or removing the server from the rack; it is unstable when not fastened to the rails.

Adequately stabilized the chassis before extending a component outside the rack. Extend only one component at a time. The rack might become unstable if more than one component is extended.

Do not stack anything on top of rail-mounted component or use it as a work surface when extended from the rack.

WARNING: The rack rails form only a shelf for the chassis to rest on. The chassis is not attached to the rails by any other means. Slipping and falling chassis will cause bodily injury or damage the chassis, so use extreme care when pulling the chassis out from the rack. Hewlett Packard Enterprise is not responsible for any injury or damage caused by the mishandling of the chassis.
