Conversely, the overall weight of the expansion enclosure is reduced as you remove parts. However, even
with parts removed, the 5U expansion enclosure is heavy. Depending on the number of parts that remain,
you might need four persons or a mechanical lift to support the weight of the expansion enclosure.
Checklist: Unpacking and installing the 5U expansion enclosure
Before you unpack and install the 5U expansion enclosure, ensure that you review and follow the
installation checklist and safety notices.
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 5U 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”
on page 27.
• Read and follow the guidelines that are described in “Weight considerations: 5U expansion enclosure”
on page 31.
• 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 5U 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 12 on page 36 shows how the enclosure is packaged for
shipment.
