EMC CX4 Series User manual

1
This document explains how to install CX4 series hardware in cabinets
that conform to the National Electrical Manufacturer’s Association
(NEMA) standards for 19-inch cabinets (in which the left and right
mounting channels are 19 inches apart). It covers mounting hardware
for 1U, 2U, 3U and 4U components, and filler panels that cover empty
cabinet spaces. In most cases, the illustrations and examples refer to
EMC®standard cabinets, which are 40U tall.

Device placement requirements
Device placement requirements
This document provides the steps required to install rails and
enclosures in both EMC and non-EMC cabinets. Unless otherwise
specified, the illustrations depict the EMC 40U and 40U-C cabinet.
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.

Device placement requirements
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.
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 that you arrange your enclosure as follows:
◆Install the standby power supply (SPS) below any other
enclosures (at the bottom of an empty cabinet).
◆Install the SPE (storage processor enclosure) directly above the
SPS.
◆Install the specially marked disk-array enclosure (DAE)-OS
directly above the SPE.
◆Install any additional disk enclosures above the DAE-OS.
Review your plan to make sure all devices will fit in the cabinet, and
review any requirements for filler panels. It is also important to verify
cabling lengths before installing any enclosure.

Power requirements
Power requirements
Power distribution must support the number of outlets required for
the device and the device power rating.
For example, each pair of power distribution panels (PDP) in the
EMC standard 40U-C cabinet can support a maximum of 24 A AC
current draw from devices connected to its power distribution units
(PDU). Most cabinet configurations draw less than 24 A AC power,
and require only two discrete 240 V AC power sources. If the total AC
current draw of all the devices in a single cabinet exceeds 24 A, the
cabinet requires two additional 240 V power sources to support a
second pair of PDPs. Use the published technical specifications and
device rating labels to determine the current draw of each device in
your cabinet and calculate the total.
Note: For high availability, the left and right sides of any rack or cabinet must
receive power from separate branch feed circuits.
Device height requirements
Device height requirements and cabinet mounting measurements are
based on NEMA units (U’s). See Table 1.
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 2 on the next page.

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 SPE, if
possible.
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 4 shows the correct channel holes
for the alignment pins.
