22 Chapter 2

m If there are devices in the system’s location that use large amounts of power, use surge

protectors or power conditions as part of the installation.

m Make sure that the power connections for the system and all other components are

grounded (according to local and national standards). Consult an electrician if you need

assistance with grounding.

m See Appendix A, “Speciﬁcations,” on page 83 for more information about electrical power

requirements for the system.

Operating Environment

The operating environment for the system’s rack must meet certain requirements:

m Verify that the temperature range of the rack’s location is within the limits established for

the system and all other components.

m Make certain that the rack’s location has adequate ventilation to maintain the necessary

temperature range. This is particularly important for a rack that is enclosed in a cabinet.

m If multiple components are installed in the rack, consider additional cooling to assure

efﬁcient operation of the system and other equipment.

Security

To ensure the security of the system and rack, note the following:

m Determine that the rack’s location is secure and that only authorized staff members or

technicians can gain access to this location.

m If using a cabinet that is not stored in a secure room, be sure that the cabinet can be

locked securely and that access to it is limited to authorized staff.

m Develop a plan for distributing and controlling keys to the rack’s location and access

codes that will allow others to manage the system over the network. Keep the plan

updated with names of key staff and relevant emergency information and procedures.

m Store a copy of essential system access information in a safe place away from the system’s

location.

m Store the Xserve RAID documentation and related materials in a central location and

inform key staff of that location. Also post electronic documents on network locations to

which users of the system will have access.

Important When planning for electrical power, make sure you have more power than

the total power requirements speciﬁed for all components. Also make certain that the

power load is distributed evenly among circuits to the rack’s location. Consult an

electrician or other expert if you need assistance with planning for the power needs of

your components.
