• Electrical (AC) power planning
Provide electrical power sources that meet the system’s requirements, optionally
including the purchase of a qualified uninterruptible power supply (UPS).
• Network and telephone line planning
Provide sufficient network and analog telephone lines.
Welcome to Site Planning for Express5800/320Ma 3.2 GHz, 3.6 GHz, and Dual-Core systems 1-1
Site Planning for Fault-Tolerant Systems
Use the “Site Planning Checklist” on page 1-3 to track your site preparation progress.
For a list of other documents related to your Express5800/320Ma system, see “System
Documentation” on page 1-5.
During the site planning and preparation processes, work closely with your facilities
group or contractor to determine space, power, and environmental requirements. Enlist
their help to provide a suitable location with sufficient alternating current (AC) power,
heating, ventilation and air conditioning (HVAC) capabilities, and network and
telephone connections.
If your system is covered by a service agreem ent and you need help with site planning,
contact the NEC Technical Support. If you have a contract with the NEC Technical
Support to install the system, contact them after you have pre pared the installation site
and moved the system to the site. For more information about NEC Technical Support,
visit http://support.necsam.com/servers.
See Appendix A, “System Specifications” for Express5800/320Ma 3.2 GHz, 3.6 GHz,
or Dual-Core system specifications and the Express5800/320Ma: Peripherals Site
Planning Guide for specifications of other components.
Site Planning for Fault-Tolerant Systems
Consider the following specific fault-tolerant features of Express5800/320Ma 3.2 GHz,
3.6 GHz, and Dual-Core systems for site planning:
• Lockstep technology means that the Express5800/320Ma 3.2 GHz and 3.6 GHz
systems contain redundant hardwa re. The Express5800/320Ma 3.2 GHz and 3.6
GHz systemssystems contain two enclosures, each cont aining a full computing
environment that consists of a CPU element and an I/O element.
If a component in a CPU element malf unctions, the correspon ding CPU element in
the other enclosure, which is processing the same information in lockstep,
continues processing without interruption. If a component in the I/O element
malfunctions, the system fails operation over to the corresponding element in the
other enclosure and continues to operate normally. Th e only consequences are
that the system is less fault tolerant, and any I/O throughput distributed between
the enclosures may be reduced. To restore full fault tolerance , an enclosure can
be replaced without taking the system offline.
• Express5800/320Ma 3.2 GHz and 3.6 GHz systems can connect to the
ActiveService Network (ASN).
Connecting a system to the ASN allows the NEC Technical Support to remotely
diagnose, troubleshoot, and resolve problems online.
1-2 Express5800/320Ma: Site Planning Guide
T o e nable connectivity to th e ASN, a modem can be attached directly to the system
and managed by Windows Server software or two partnered Virtual Technician
Modules (VTMs) in the system. The VTMs can also connect to the ASN through
their Ethernet ports, if the network to which they are attached has Internet access.
Systems that connect to the ASN using partnered VTMs provide the highest level
of availability. VTMs provide ASN connectivity even when the operating system is
not operational. VTMs also allow internal adminis trators to re mo te ly se rvice the
system over a t elephone line or IP netw ork, regardless of the state of the operating
system.
Without VTMs, ASN connectivity is only possible if the operating system is
operational.
Site Planning Checklist
Referring to the information in this document, answer t he following questions:
Planning for ASN Connectivity
❏ Will your system use VTMs to connect to the ASN?
❏ If your system uses VTMs, will you connect them to a network so that you can
manage the server from a remote system? Are there mainten ance network
connections to which you can connect the VTMs?
Site Planning Checklist
❏ If your VTMs are connected to a netw ork, does the network have Internet
connectivity so that the system can connect to the ASN without a modem?
❏ If your system uses an ASN modem, do you have an external analog telephone line
available for the modem?
NOTE
A dedicated phone line provides the most reliable service.
ASN calls routed through a PBX may be slo w due to load
on the PBX, or may not complete successfu lly due to
disconnections. If you must use a PBX, do not route the
telephone extension through a switchboard; instead,
provide a direct-dial analog number.
❏ Do you hav e an additional telephone line and telephon e near the operator’ s station
for voice communications when calling for support?
Planning for Optional Components
❏ The system contains four 10/100/1000 megabits-per-second (Mbps) Ethernet
ports. Will your system additionally include any of the following PCI adapters for
network communications? If so, indicate how many of each and plan network
connections for all Ethernet ports you will use.

For requirements related to supplying your own cabinet and monitor, see:
• “Cabinet Requirements” on page 2-1
• “Monitor Requirements” on page 2-4
Cabinet Requirements
If you are providing your own cabinet for an Express5800/320Ma 3.2 GHz, 3.6 GHz, or
Dual-Core systems, make sure the cabinet contains a rack that is 19-in. wide and that
meets the Electronic Industries Association (EIA) 310-D standard.
Make sure that:
• The cabinet contains two front and two rear v ertical EIA rails, one in each corner of
the cabinet, that have the EIA universal square-hole pattern as defined in the EIA
310-D specification.
• The front vertical rails extend at least 0.5 in. (1.27 cm) beyond the inside edge of
the accessory leg, if present, to allow the mounting rails to be fit ted. See Figure 2-1.
Cabinet and Monitor Requirements
2-
• The distance between the front and r ear vertical rails is between 24 .5 in. and 30 in.
(62.23 cm and 76.20 cm).
• The vertical mounting rails accept 10-32 cage nuts and mounting hardware.
• The distance between the front vertical rails and the inside of the front door is at
least 3.0 in. (7.62 cm).
• The distance between the rear of t he system chassis and the inside of the rear do or
is at least 6.0 in. (15.24 cm).
• The vertical mounting rails are plated or some other method is used to ensure
continuity for g rounding between installed equipment.
• Cable management brac kets are pro vided to support and constrain data and power
cords so that the cables do not interfere with air flow out of the rear of the
enclosures, and so that the connectors do not disconnect or break.
• The cabinet provides enough stability so that system components pass T elcordia
®
GR-63-CORE Section 5.4.2 regulations for operational vibration.
Cabinet and Monitor Requirements 2-1
Cabinet Requirements
• To prevent stray voltages, all components are grounded together through the
vertical mounting rails to the cabinet frame, and then to local building ground. To
ensure signal quality , us e a grounding cable pr ovided by NEC Solutions (America),
Inc. for local building ground.
• There is a plan for maintaining cables and wires to the cabinet by either running
them under the floor or placing them overhead in an overhead cable tray.
• Air flows through the cabinet from f ront to back.
• Filler panels cover any unused rack space to prevent air recirculation.
• V ents are evenly distributed on the front and rear doors and comprise at least 63%
of the surface area.
Figure 2-1 shows the required rail clearance between the front vertical rails and the
inside edge of an accessory leg.
NOTE
