Before unpacking, installing, wiring, or making connections to the Evolocity II cluster, the technician 

responsible for these activities should become familiar with the precautions, warnings, and procedures outlined 

in this guide. 

Antistatic Procedures 

To prevent Electrostatic Discharge (ESD), adhere to antistatic procedures at any time you are handling 

sensitive electrical components: 

• Wear an ESD antistatic smock to eliminate and prevent static buildup on clothes. 

• Place an ESD wrist strap on your wrist and attach an alligator clip to the proper Earth ground location. 

Electric Shock! 

Use only grounding straps with internal resistors to ground yourself to the equipment. Low resistance 

wires could cause electrocution or serious burns. 

Electrical Safety 

To avoid electrical shock and fire hazard, take the following precautions: 

• Verify that the Alternating Current (AC) supply voltage and circuit breaker values are correct for the 

Evolocity II hardware. 

• Ensure that the rack is placed close enough to the power source that a power extension is not necessary. 

• If a re-configuration of the power source is required, have it inspected and approved by a certified electrician 

or electrical engineer. 

• Securely fasten and route all cables in a safe and uncluttered manner. 

Certifications

Preparing for Installation 

Preparing the Site 

Use the following guidelines to prepare the site where you will install your cluster. 

Space Requirements 

Access to the front and rear of the cluster requires at least 20-inch (50.8 cm) aisles. If you place clusters in 

multiple rows, rack enclosures may share the aisle space. The following table lists the space requirements for 

common rack enclosures used with Evolocity II clusters: 

Cabinet Height Width Depth 

47U 90 in. (228.6 cm) 23.5 in. (59.7 cm) 36.5 in. (93.2 cm) 

42U 72 in. (182.8 cm) 23.5 in. (59.7 cm) 31.5 in (80 cm) 

20U 46.6 in. (118.3 cm) 23.5 in. (59.7 cm) 31.5 in. (80 cm) 

15U 27 in. (68.5 cm) 23.5 in. (59.7 cm) 36.5 in. (93.2 cm) 

Support Requirements 

Clusters are heavy pieces of equipment with the weight concentrated in a small area. A rack enclosure with 

hosts, switch, an Icebox control unit, an un-interruptible power supply (UPS), and cabling can weigh 

approximately 1,300 lbs (590 kg). To estimate the weight of your cluster, refer to the following table (items 

marked with an * are approximated).

Note 

Inspect the floor intended to support the cluster to determine that it has sufficient structural integrity 

to carry the load applied by the cluster—to ensure safety, consult a structural engineer. The most ideal 

solution is to install a raised floor specifically designed for computer centers. A flooring system of this 

type provides the maximum convenience and safety, allowing you to run cables under the floor and 

providing a means by which cold air may be forced into rack enclosures to ensure efficient cooling. 

Cooling Requirements 

Clustered computers produce potentially large amounts of heat that can drastically reduce the life span of your 

cluster components. Although Evolocity II clusters operate at approximately 22° F (11° C) cooler than 

standard 1U and 2U solutions, you should take adequate steps to prevent the cluster from overheating. 

Warning! 

Hosts require substantial cooling targeted specifically at each host. Hosts that are not cooled 

sufficiently may shut down or suffer irreparable damage. 

One of the most significant factures in ensuring adequate cooling is room size. A large room with high ceilings 

allows heat to rise away from the computing equipment, providing plenty of airflow in and around the cluster. 

If you purchased a cluster that contains more than five hosts, it may be necessary to equip your room with an 

additional, commercial air-conditioning unit. Most computer rooms maintain an average temperature between 

60–68° F (16–20° C). If your cluster produces enough heat to overwhelm your present cooling system, 

additional cooling is a must. The room should have sufficient air conditioning capacity to support the cooling 

needs of the entire cluster and use controls that prevent excessive temperature fluctuation. 

To ensure that the equipment used to cool the cluster is adequate, determine the total power consumption (in 

watts) of all devices in the room and convert that number to British Thermal Units (BTUs). This is 

accomplished using the formula watts x 3.412 = BTU. For specific altitudinal cooling requirements, refer to 

the table on page 3.

Static pressure is equally as important as temperature. Linux Networx recommends the static pressure be no 

less than 0.5 inches as measured in front of the rack enclosure. This will require a high-volume air grate such as 

the “Tate Access Floor GrateAire” (part number 8515). The recommended air volume is 350 Cubic Feet per 

Minute (CFM) per each five hosts in the subrack. The following is a comparison between a typical floor grate 

(on the right) that allows approximately 25% air flow and the Tate Access Floor GrateAire (on the left) that 

allows approximately 75% air flow.

Power Requirements 

Evolocity II clusters require a minimum 20A circuit for each five hosts in a rack—each host may use up to 3A 

of power (or more). Solid, clean power is important for clusters. Unconditioned power used over a long period 

of time can seriously shorten a cluster's life span. In addition, a power spike or surge can adversely affect the 

integrity of the operating system and cause other system damage. 

Note 

Linux Networx strongly recommends cluster power protection, such as a UPS, for each cluster. Use 

devices that provide ample power backup and excellent power conditioning. 

POWER CONSUMPTION 

In order to estimate the total power consumption, determine the power consumption (in watts) of all devices 

in the room with your cluster. This includes (but is not limited to) information on the power consumption of: 

• Each master and slave host in the equipment rack. 

• Each stand-alone disk or tape device, UPS, or other backup device. 

• Each network switch, hub, and router in the equipment rack. 

The following table contains a guide to the power consumption of typical cluster components.

Evolocity II host 400 

Switch (24 port) 85 

UPS 125 



Unpacking and Preparing the Cluster 

Unpacking and Preparing the Cluster 

Linux Networx recommends that your cluster should be unpacked only by an authorized Linux Networx 

representative. If you are unpacking and setting up the cluster yourself, follow the instructions in this guide to 

remove the rack enclosure and hosts from the container. 

Before you begin, inspect all shipping cartons for evidence of physical damage—if a carton is damaged, 

request that the carrier's agent be present when you open the carton and make all packing materials and 

contents available for the agent’s inspection. If your equipment is damaged or if you are missing a host, contact 

Linux Networx immediately. 

Warning! 

To prevent personal injury, DO NOT attempt to lift the rack enclosure—rack enclosures can weigh 

up to 500 lbs. Hosts are sensitive pieces of computer equipment. To avoid damaging hosts, do not 

drop them or place them where they can be exposed to the elements. 

Tip 

The door on the shipping crate is designed to lower into a ramp. Rack enclosures are equipped with 

wheels that allow them to roll from the shipping crate to another location. 

Shipping and Storing the Cluster 

After unpacking the rack enclosure(s) and other materials, return the original shipping crates and green boxes 

to Linux Networx using the return address labels included in the envelope marked “Return Address Labels.” 

Should you have any questions about returning shipping materials, contact Linux Networx Customer Support. 

Note 

International shipping requirements vary from continental U.S. shipments. With international 

shipping, most key components ship separately in form-molded foam boxes. There is no need to 

return these boxes to Linux Networx; however, you may want to save a few boxes in the event you 

need to return a host. 


8 Host Installation 

Host Placement 

Host Installation 


Evolocity II clusters range in size and may contain as few as five hosts or as many as several thousand. Hosts 

are numbered consecutively and, to prevent problems with your cluster, must be placed in the rack according 

the order indicated by the label on the rear of each host. 

Note 

If you purchased an Icebox with your cluster, refer to the Icebox User’s Guide for information on 

how to attach the Icebox to the rack enclosure. One Icebox is required for every ten hosts. 

Inserting a Host 

Evolocity II hosts are inserted from the front of the rack enclosure. To insert a host, grip the handhold part of 

the bezel with one hand and hold the bottom of the host with your other hand. Align the host in the rack slot 

and slide the host into the rack until it seats in place. 

Warning! 

Each host has a specific location in the rack enclosure. The cluster will not function properly if hosts 

are not installed in their correct locations. 


Host Installation 9 


Removing a Host 

Before removing a host from the rack, turn off power to the host and disconnect all cabling connected to the 

rear of the host. To remove a host from the rack enclosure, grip the bezel and lift the host until it clears the 

notch that holds it in place—then pull the host out from the cluster. As you slide the host out of the rack, use 

one hand along the bottom of the host for support. 

Warning! 

Hosts can weigh up to 25 lbs each. DO NOT drop hosts—damaged hosts may become inoperative. 


10 Cabling the Cluster 

Evolocity II and Icebox Cabling 

Cabling the Cluster 

In order for your Evolocity II cluster to work properly, hosts, Iceboxes, and other cluster components must be 

correctly cabled to each other. Before making cable connections, ensure that the cluster is in an area that allows 

access to both the front and the rear of the rack enclosure. This site should conform to the site preparation 

guidelines and specifications described in Preparing for Installation on page 1. 


This section discusses how to properly connect cabling to the Evolocity II hosts, the Icebox, and the 

Clusterworx Master Host. To assist in locating various Evolocity II and Icebox parts, bold letters in 

parentheses (e.g., “(A)”) appear throughout this section. These letters correspond with letters used in the 

following Evolocity II and Icebox illustrations. 

Note 

The I/O ports present on an Evolocity II system can vary depending on your system configuration. 

The following illustration represents one of several possible I/O implementations.
