14 Setup

Prerequisites for the initial server setup

Procedure

Verify that the optimum environmental requirements are satisfied.

Review and observe the server warnings and cautions.

Prepare the following items:

◦ Keyboard, mouse, and monitor

Ethernet cables of an appropriate length for each of the LAN and/or WAN connections.

◦ ◦ Verify the network settings needed to integrate the server into the site network, in particular from an IP

addressing perspective and from a domain perspective.

◦ Verify that there are sufficient ports available on the devices to which the server will be connected (for

example, router, LAN switch).

Optimum environment

When installing the server, select a location that meets the environmental requirements described in this section.

Site requirements

The server may be located in an office space or a purpose-made equipment room. The location must:

• Comply with local health and safety regulations.

• Be clean, tidy, and free of excessive dust and vibration.

• Be in an area in which the server cannot easily be disconnected from its power source.

• Not be adjacent to or underneath any area or piece of equipment where liquid is stored.

• Not be in a place where the server might be bumped, scratched, or disturbed.

• Be within an area that is ideally locked or at minimum not accessible to unauthorized personnel.

• Be within patching distance, directly or via cable management cross-patches, of the location of the WAN connection and the switch that supplies the office/room floor network ports.

Space and airflow requirements

Leave at least a 10 cm (4 in) clearance space at the front and back of the server for proper ventilation.

CAUTION:

The server draws in cool air through the ventilation openings on the front side, and expels warm air through the ventilation openings on the rear side. Do not block these openings. Failure to observe this caution will result in improper airflow and insufficient cooling that can lead to thermal damage.

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

Prerequisites for the initial server setup 15

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 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 information technology equipment by licensed electricians. This equipment is designed to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFP for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, see the product rating label or the user documentation supplied with that option.

CAUTION:

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

When installing more than one server, you might have to use additional power distribution devices to safely provide power to all devices. Observe the following guidelines:

• Balance the server power load between available AC supply branch circuits. Do not allow the overall system AC current load to exceed 80% of the branch circuit AC current rating.

•

• Do not use common power outlet strips for this equipment.

• Provide a separate electrical circuit for the server.

A-75, 1992 (code

Electrical grounding requirements

The server must be grounded properly for proper operation and safety. In the United States, you must install the equipment in accordance with NFP local and regional building codes. In Canada, you must install the equipment in accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries, you must install the equipment in accordance with any regional or national electrical wiring codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed or certified grounding-type devices.

Because of the high ground-leakage currents associated with multiple servers connected to the same power source, Hewlett Packard Enterprise recommends the use of a PDU that is either permanently wired to the building’s branch circuit or includes a nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this purpose. Using common power outlet strips for the server is not recommended.

Electrostatic discharge

Preventing electrostatic discharge

About this task

To prevent damaging the system, be aware of the precautions you must follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

Operations 21

Procedure

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. Place parts on a grounded surface before removing them from their containers.

•

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

•

Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.

Power up the server
