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.

Topics are:

Device placement requirements

Device placement requirementsThis 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.

EMC2203Front Rear

EMC Rails and Enclosures (CX4 Series Storage Systems) Field Installation Guide 3

Device placement requirements

Position in the cabinetDevices 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 requirementsPower 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 requirementsDevice 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 enclosure in the cabinet

WARNING

The enclosure is heavy and should be installed into a rack by two people. To avoid personal injury and/or damage to the equipment, do not attempt to lift and install the enclosure into a rack without a mechanical lift and/or help from another person.

L’armoire étant lourde, sa mise en place sur une rampe nécessite deux personnes. Afin de ne pas vous blesser et/ou endommager le matériel, n’essayez pas de soulever et d’installer l’armoire sur une rampe sans avoir recours à un relevage mécanique et/ou à l’aide d’une autre personne.

Das Gehäuse ist schwer und sollte nur von zwei Personen in einem Rack installiert werden. Zur Vermeidung von körperlichen Verletzungen und/oder der Beschädigung des Gerätes, bitte das Gehäuse nicht ohne die Hilfe einer zweiten Person anheben und einbauen.

Il contenitore è pesante e dev'essere installato nel rack da due persone. Per evitare danni personali e/o all’apparecchiatura, non tentare di sollevare ed installare in un rack il contenitore senza un sollevatore meccanico e/o l’aiuto di un’altra persona.

Debido a su considerable peso, la instalación del compartimento en el bastidor deben realizarla siempre dos personas. Para evitar daños personales o en el equipo, el compartimento no debe levantarse ni instalarse en el bastidor sin la ayuda de un elevador mecánico o de otra persona.



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 12.

Figure 12 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 each rail. The tabs secure and support the rear of the enclosure.

If the chassis does not slide all the way into the cabinet, you may need to 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 (one on each rail) that secure the rails to the front channels.

Installing a DAE enclosure in the cabinet

WARNING






CAUTION!Without proper equipment and procedures, you risk damaging disk drives any time you remove, store, or install them. Do not remove disks prior to installing the chassis.





Figure 43 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 approximately 14 inches from the front of each rail. The tabs secure and support the rear of the enclosure. See Figure 44 on page 55.

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 four screws (two on each rail) that secure the rails to the front channels.

3. Secure the front of the enclosure to the front vertical channels of the cabinet using four M5 12.7 mm screws (two per side), as shown in Figure 45.

Note: The front screws also help to secure the latch bracket mounted on the front of the enclosure.

If you are installing the enclosure in a NEBS-compliant environment, secure the unit to the front channels with the four shape thread rolling screws supplied with your installation hardware in part number 100-560-644.

Installing front filler panels

Installing front filler panels1U, 2U, and 4U filler panels fill gaps in the NEMA rack. The latch bracket will secure any filler panel to the cabinet. The size of the filler panel determines the orientation of the latch bracket on the front channel.

This section shows you how to install the latch brackets and filler panels in empty spaces in the front of the cabinet.

◆ To install latch brackets for a 1U or 2U space, go to the next section.

◆ To install latch brackets for a 3U space, go to page 59.

◆ After you install the latch brackets, go to page 60 for instructions on installing the filler panel.

Installing the 1U or 2U latch brackets Follow these steps to orient and install the 1U or 2U filler panel latch brackets.

Note: The latch bracket is installed in exactly the same way for both the 1U and 2U filler panels. The 2U bracket mounts on the lower of two 1U spans on the front channels. See Figure 47 for the location of the 2U latch bracket on the channels.
