48-drive enclosure front panel components
2U48 enclosures support dual-IOM configuration, and are equipped with two redundant AC power supply
modules. Each AC PSU is equipped with a power switch (see Figure 104
on page 126 ). When the enclosure
bezel is installed, the 2U48 front panel looks the same as the 2U12 front panel (see the bezel, callouts,
and table entries shown in Figure 2 on page 15 for reference).
TIP: See Enclosure bezel attachment and removal on page 104 and Figure 85 on page 105 (2U48).
2U48 enclosure bezel removed
To access the drawers, you must remove the enclosure bezel (shown removed in Figure 3).
