Identify the hardware components

You should become familiar with the external components of the 5U expansion enclosure.

Components on the front of the enclosure

Figure 1 shows the front of the 5U expansion enclosure. In the figure, all parts are installed in the enclosure.

Figure 1. Features on the front of the 5U expansion enclosure

1 Display panel indicators
2 Rack retention thumb screws
3 Power® supply unit indicators
4 Power supply units (PSUs)
5 PSU fascia (1U)
6 Front fascia (4U)

However, as Figure 2 shows, the 4U and 1U fascias are packaged separately. You must attach them to the front of the 5U expansion enclosure as part of the initial installation process.

Support rails

Figure 4 shows the support rails for the expansion enclosure. The support rails are packaged separately from the expansion enclosure.
