Before you set up your system environment, you must verify that the
prerequisite conditions for the system are met.
About this task
Before you start the installation process, review the following questions. The questions
and related topics can help you to determine whether your environment supports all of the hardware
components in your system. For example, components can include several control enclosures of the
same model, different models of expansion enclosures, redundant power supplies (if supported by your
system), and required cables for power and connectivity.
- Does your physical site meet the environment requirements for your system?
- Do you have adequate rack space for all of your system hardware?
For example, some
expansion enclosures require two Electronic Industries Alliance (EIA) units (2U) of space and can be
placed in any rack location. Other expansion enclosures require 5Us of space and must be installed
near the bottom of the rack.
- Do the power circuits that you are planning to use have sufficient capacity and the correct
sockets for your
installation?
- A clearly visible and accessible emergency power off switch is
required.
- For redundancy, two independent
power circuits are required. One circuit connects to each power supply in each enclosure.
- Have you provided appropriate connectivity by preparing your environment?
- Do you have a notebook computer available in the unusual event that a service action
requires them?
