Device placement requirements

Figure 1 Typical cabinet front and rear views

Before attaching the mounting rails or trays in any cabinet, you must

decide where to put them. Where you install the devices depends on

the kinds of devices you will install and the height of each device.

Position in the cabinet

Devices with internal cooling fans or blowers that move air from

front to back (or vice versa) and not from beneath or above have no

special cooling requirements that direct placement in the cabinet. All

of the storage systems and enclosures mentioned in this document

have fans or blowers that move air from front to back.

Device placement requirements

In most cases, you should install devices starting at the bottom of the

cabinet. Installing bottom to top offers the advantages of stability and

convenient cable access from beneath.

We recommend the device placement configuration shown (from the

rear) in Figure 2.

Figure 2 Sample device placements with an SPE3

Note: Place the disk enclosure (DAE3P) that contains specially marked "array

software" disks 0-4 as close as possible to the CX3-series storage processor

enclosure (SPE3). In most cases, install that first enclosure (sometimes called

the DAE3P-OS, or vault) directly above the standby power supply (SPS).

Stack additional DAE3Ps directly above the DAE3P-OS.

Power requirements

Review your plan to make sure all devices will fit in the cabinet. It is

also important to verify cabling lengths before installing any

enclosure.

Power requirements

Power distribution must support the number of outlets required for

the device and the device power rating.

Use the published technical specifications and device rating labels to

determine the current draw of each device in your cabinet and

calculate the total. Use the following values to calculate current draw

for CX3-series storage-system components.

Note: These are maximum ratings for a class family, to guide the

sizing of power distribution components at the rack level. Since model

configurations and drive types vary, they may not be appropriate to

estimate typical power consumption.

Note: For high availability, the left and right sides of any rack or cabinet must

receive power from separate branch feed circuits.

SPE3, DAE3P, and SPS operating limits

The ambient temperature specification is measured at the front bezel

inlet. The site must have air conditioning of the correct size and

placement to maintain the specified ambient temperature range and

offset the heat dissipation listed below.

IMPORTANT: For systems mounted in a cabinet, the operating limits listed

above must not be exceeded inside the closed cabinet. Equipment mounted

directly above or below an SPE3 storage system must not restrict the

front-to-rear airflow of the storage system. The cooling airflow through the

storage system is approximately 64 cubic feet per minute (cfm). Cabinet

doors must not impede the front-to-rear airflow. The cabinet must exhaust air

at a rate that is equal to or greater than the sum of the exhaust rates of all the

equipment mounted in the cabinet. For example, in a cabinet containing one

SPE3 (64 cfm) and six DAE3Ps (55 cfm), the cabinet must exhaust at least

64+6x55 cfm, which equals 394 cfm.

Device height requirements

Device height requirements and cabinet mounting measurements are

based on NEMA units (U’s). See Table 1.

Requirement Description

Ambient temperature 10°C to 40°C (50°F to 104°F)

Temperature gradient 10°C/hr (18°F/hr)

Relative humidity 20% to 80% noncondensing

Elevation 2438 m (8,000 ft) at 40°C

3077 m (10,000 ft) at 37°C

4U 7 inches

6EMC Rails and Enclosures (CX3-10 Class and CX3-20 Class Storage Systems) Field Installation Guide

Device height requirements

The predrilled holes in the cabinet channels are based on the U

measurement. The holes are predrilled at distances of 1/2 inch, 5/8

inch, 5/8 inch (totaling one U), then 1/2 inch, 5/8 inch, 5/8 inch

(another U), and so on. On EMC 40U and 40U-C cabinets, the 1U

increments are marked by a horizontal line or small hole in the

channel. See Figure 3 on page 7 on the next page.

Installing a 1U storage processor enclosure (SPE3) in a cabinet

Follow these steps to install the enclosure on the rails in the cabinet:

1. With help from another person, lift the enclosure and, from the front

of the cabinet, slide the enclosure onto the rails as shown in

Figure 6.

Figure 6 Sliding an enclosure onto the mounting rails

When the enclosure slides to the back of the cabinet, the two

notches in the rear of the enclosure insert into the rear tabs on the

back corner of each rail. The tabs secure and support the rear of

the enclosure.

Note: If the chassis does not slide all the way into the cabinet, you may

need to further loosen the screws that hold the rear of the rails in place,

then adjust the rails to allow the tabs to fit into the notches.

2. Once the enclosure is completely seated into the rear tabs, tighten

the two screws (the top one on each rail) that secure the rails to

the front channels.

Removing the filler panels

In most cases, the front space into which you will install your

component is covered by a filler panel, which is attached to latch

brackets.

Remove any filler panel, then use a flat-blade screwdriver or similar

tool to pry off the latch brackets.

Installing the rails in the cabinet

This section describes how to mount the rails in the cabinet.

1. After you decide where in the cabinet you want to install the SPS

tray, find the unoccupied 1U section on the rear channels. We

suggest that you install the SPS tray immediately above the SPE3,

if possible (refer to the device placement examples beginning on

page 3).

2. From the front of the cabinet, insert the alignment pin on one

mounting rail assembly into the middle hole of the selected 1U

space on a rear channel. Figure 8 shows the correct channel holes

for the alignment pins.
