4. Reinstall the trim cover plate with the M4 flat head screws you removed
in step 1.
Installing blanking panels
Blanking panels should be installed to cover any empty space at the front
of the rack. This will ensure adequate airflow to the equipment in the rack
if the rack is not completely filled.
When installing blanking panels, follow these steps:
1. Place the blanking panel on the rack as a template to determine which
holes will require cage nuts.
2. Insert the cage nuts.
3. Secure the panels to the rack by screwing them onto the rack at the cage
nut locations.
Post-installation considerations
The following sections provide guidelines to consider after you install
equipment in the Hitachi rack.
Casters
The casters facilitate movement of the rack across short distances in order
to position it for final installation. As soon as the rack is in its final position
for installation, make sure that the full weight of the rack is supported by
the leveling feet.
The casters can only support the weight of the rack with installed
components for short periods of time and not designed to support the full
weight of the rack on a long-term basis. If this occurs, the casters may be
damaged.
Inspection and cleaning
Observe the following precautions when inspecting and cleaning the rack.
• If the equipment must be powered off, perform the power-off sequence
described in Power On/Off procedures on page 5-1, before proceeding
with maintenance.
• Do not work on the equipment or rack in a damp or flooded
environment.
• Do not obstruct access to the rack with parts or tools.
• If the rack has a door, before performing the work with the door open,
take off metal watches or jewelry to prevent electric shock. If you wear
metal-frame glasses, do not touch the equipment.
• Ensure that loose clothing, jewelry, or hair does not become tangled in
moving components.
