Preparing the rack
Important: Before you install the storage expansion enclosure in a rack, keep in
mind the following considerations:
v
Review the documentation that comes with your rack enclosure for safety and
cabling considerations.
v
If you are using a non-IBM rack or cabinet, review the information in
Appendix C, “Specifications for non-IBM rack installation,” on page 113.
v
Do not extend more than one device out of the rack cabinet at the same time.
v Install the storage expansion enclosure in a maximum 35° C (95° F) environment.
v
To ensure proper airflow, do not block the air vents; 15 cm (6 in.) of air space is
sufficient.
v
To ensure 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 expansion enclosure to a properly grounded outlet.
Complete the following steps to prepare the rack before you install the storage
expansion enclosure:
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
power, network, and other external cables.
5.
Install any additional interface cables and power cables.
After you have completed these steps, continue with “Installing the support rails.”
Installing the support rails
Attention: Duplicate copies of the rack mounting templates are provided in
Appendix B, “Rack mounting template,” on page 109. If you want to tear out the
templates from this document for easier use, use the copies in Appendix B, “Rack
mounting template,” on page 109 rather than the copies provided in this section.
Use the following templates (Figure 9 on page 25 and Figure 10 on page 26) to
identify the proper locations for inserting M5 screws when mounting the support
rails and EXP395 to a rack. The locations for the M5 screws are highlighted in the
templates.
The EXP395 is 3 U high. Align the template with the rack at a U boundary. U
boundaries are shown as horizontal dashed lines in the rack mounting templates.
Note: The mounting holes that are shown in the following templates are square.
The holes in your rack might be round, square, or threaded.
