The dell rack is a sturdy, practical design and solidly built, delivered with Enterprise service, support and reliability.

6 The dell PowerEdge rack enclosures are offered in three height options: 24U (2420), 42U (4220), and 48U (4820); each of these racks is available in the standard 600mm x 1070mm dimensions, to fit within a two- tile floor plan layout. dell has introduced both wide and deep versions of the PowerEdge rack enclosures to address specific market requirements for additional space for power and cable management. The 42U and 48U heights are available in the wide form factor, 750mm wide x 1070mm deep, and the deep form factor, 600mm wide x 1200mm deep. The dell racks are complemented with a range of products that include basic, metered, and managed power distribution units (PDUs), rack - mount uninterruptible power supplies (UPSs), digital keyboard/video/monitors (KVMs), and other accessories. All of these form factors adhere to the EIA- 310- E standard for rack mounting of electronics, ensuring that the mounting posts for installing components are configured for 19- inch equipment, while the exterior of the rack is set to the specified dimensions.

7 This ensures compatibility with existing equipment while providing more options for cable and power cord routing. Not only do dell PowerEdge servers fit in these 19- inch racks, but other Enterprise equipment fit as well, including dell PowerVault and dell EqualLogic storage, and dell PowerConnect networking switches, plus routers, hubs, and telephony equipment. Built with adjustable vertical mounting posts within the rack , dell racks are designed for use in almost any environment, such as an Enterprise data center, a high- performance computing center, a remote office, a wiring closet, or a factory floor. Benefits Table 1 lists the benefits of the rack enclosures . Table 1. Benefits Benefits Detailed descriptions Height options dell PowerEdge rack enclosures offer three height options: 24U, 42U, and 48U. Form factors 42U and 48U are available in standard, wide, and deep form factors Door design Excellent airflow with 80% perforated doors Cabling and PDUs Superb design facilitates more cabling and power distribution options With a static load rating of 2,500 lbs and three form factors to choose from, the PowerEdge 42U.

8 And 48U rack enclosures can provide the capacity you need to hold a full complement of data center equipment. These sizes are available in three form factors: Standard: 600mm wide x 1070mm deep Wide: 750mm wide x 1070mm deep Deep: 600mm wide x 1200mm deep 5 PowerEdge rack enclosures Technical Guide Wide (750mm) racks in both 42U and 48U heights have three inches more space on each side for cables and PDUs for networking, blade server and other installations that need to route cables along the sides. The wide design of the 4820W and 4220W also moves the PDU trays even farther away from the rack mounting posts, allowing more room for cables in the sides and back, helping reduce contention between power cords, cables and installed equipment. Deep (1200mm) racks offer more space in the back for cables and PDUs for high- density installations.

9 The 4820D and 4220D racks have extended PDU trays in the back of the rack , which can hold up to four vertical- mount full- height PDUs on each side. This extra space can be used for additional power management or for routing cables. PDUs can also be mounted with a 90- degree rotation so that the power cords point toward the back of the rack rather than toward the middle. 6 PowerEdge rack enclosures Technical Guide 2 rack enclosure features Table 2 contains the basic specifications for the rack dimensions and weights, while Table 3 provides more details on features and specifications for the rack enclosures . enclosure specifications Table 2.
