perforated tiles immediately in front of the racks.
v Where racks are in rows front-to-front or back-to-back, there should be a gap of
at least 1220 mm (48 in) separating the rows.
v To ensure correct air flow within each rack, the rack filler plates must be installed
in unused positions. Also, all the gaps in the front of the racks must be sealed,

Disk Drive Acclimation
If you bring a disk drive module into the operating environment from an environment
where the temperature is outside the specified operating range (see Environment),
allow the disk drive module time to acclimate to the operating environment
(approximately 2 hours). Remove the disk drive module from any shipping packaging,
but leave it in its sealed plastic bag (if present) to prevent condensation forming.
Power Sequencing
You can configure the power sequencing of the 2104 Models DU3 and TU3. For more
information, see “Drive Autostart switch” on page 10.
