Preparing The Rack Cabinet; Installing The Support Rails - IBM System Storage DS5020 Installation, User's, And Maintenance Manual

v Sufficient space to install the storage subsystem
v Enough stability to support the weight of the fully configured storage subsystem
Make sure that all requirements, such as floor space, air conditioning, and electrical
service, have been met. Other site preparation activities include the following tasks:
v To make sure that there is enough room to move around the cabinet and install
v Install uninterruptible power supply (UPS) devices.
v If applicable, install host servers with Fibre Channel host bus adapters (HBAs),
v Route interface cables from the Fibre Channel HBA ports in the hosts or Fibre
v Route main power cords to the installation area.

Preparing the rack cabinet

Important: Before you install the storage subsystem in a rack cabinet, keep in mind
the following considerations:
v Review the documentation that comes with your rack enclosure for safety and
v Install the storage subsystem in an environment with a temperature of 22° C (72°
v For proper airflow, do not block the air vents; allow for at least 15 cm (6 in.) of air
v For optimal rack stability, load the rack starting at the bottom.
v If you install multiple components in the rack, do not overload the power outlets.
v Always connect the storage subsystem to a properly grounded outlet.
v Always connect the IBM-certified rack power distribution units (PDUs) to at least
Complete the following steps to prepare the rack cabinet before you install the
storage subsystem:
1. Move, unpack, and level the rack at the installation site (if needed).
2. Remove the external rack panels.
3. If necessary, stop all I/O activity to the devices in the rack.
4. If necessary, turn off all drive enclosure and rack power. Disconnect existing
5. Install any additional interface cables and power cables.
After you have completed these steps, continue with "Installing the support rails."
