Before you begin

CAUTION:

The weight of this part or unit is more than 55 kg (121.2 lb). It takes specially trained persons, a lifting device, or both to safely lift this part or unit. (C011)

CAUTION:

To avoid personal injury, before lifting this unit, remove all appropriate subassemblies per instructions to reduce the system weight. (C012)

Important: Before you unpack, move, install, or service the 2145-92F expansion enclosure and its parts, always complete the following tasks:

• Read and follow the safety notices and instructions, as described in Safety notices and considerations: 2145-92F.
• Read and follow the guidelines that are described in Weight considerations: 5U SAS expansion enclosure.
• Ensure that a suitably rated mechanical lift is available to support the weight of the expansion enclosure as it inserted into the rack for installation.

About this task

The 2145-92F expansion enclosure and most parts are shipped together in one large box. A tray on the top of the enclosure contains the front fascia (1U and 4U pieces), the cable management arm (CMA), and the slide rail kit; you must install these parts. Figure 1 shows how the enclosure is packaged for shipment.

•  1  Slide rail kit
•  2  Cable management arm
•  3  Fascia

Other parts, such as the cover, secondary expander modules, and fans, are installed in the enclosure. However, due to weight considerations, you must remove some parts and then reinstall them as part of the initial installation process.

Note: Drives are not included in installation package for the enclosure; they are provided in a separate package.

1. Remove the cardboard tray that contains the slide rails, cable management arm, and fascia from cardboard box in which the expansion enclosure was shipped.
2. Remove the foam end pieces from the top of the 2145-92F expansion enclosure.
3. Cut the corners of the shipping box and fold them down to uncover the sides and faces of the expansion enclosure, as shown in Figure 2.

8. Attach the remaining sections of the support rails to the rack, as described in step 6 in Installing or replacing the support rails: 2145-92F.
9. Move the mechanical lift to the front of the rack. Align the inner section of the rails with the mid section of the rails that are extending from the rack.
10. On each side, push the inner section and middle section of the rails together until they click and will no longer separate, as described in step 1 in Installing or replacing an expansion enclosure in a rack: 2145-92F.
11. Remove the 4U and 1U fascia from the boxes in which they were shipped, as shown in Figure 3.

    

    •  1  4U fascia (front)
