• Grounding cable (6 AWG recommended), sized according to local and national installation
requirements; the required length depends on the proximity of the IBM c-type SAN Device to proper
grounding facilities.
• Wire-stripping tool
• For the IBM c-type SAN Device, you need a mechanical lift to handle the weight of the fully-loaded
chassis.
Installation Guidelines
Follow these guidelines when installing the IBM c-type SAN Device.
• Plan your site configuration and prepare the site before installing the chassis. We recommend that you
use the site planning tasks listed in Appendix C, "Site Planning and Maintenance Records," on page
159.
• Ensure that there is adequate space around the switch to allow for servicing the switch and for
adequate airflow. Airflow requirements are listed in Appendix A, "Product Specifications," on page
135.
• Ensure that the air-conditioning meets the heat dissipation requirements listed in Appendix A, "Product
Specifications," on page 135.
• Ensure that the rack meets the requirements listed in "Rack Requirements" on page 45.
• Ensure that the site power meets the power requirements listed in Appendix A, "Product
Specifications," on page 135. You can use an uninterruptible power supply (UPS) to protect against
power failures.
CAUTION : Avoid UPS types that use ferroresonant technology. These UPS types can become
unstable with systems such as the IBM c-type SAN Director series, which can have substantial
current draw fluctuations because of fluctuating data traffic patterns.
• Ensure that circuits are sized according to local and national codes. For North America:
• The 3000-W AC power supplies require a 20-A circuit.
• If you are using 200/240 VAC power sources in North America, the circuits must be protected by two-
pole circuit breakers.
CAUTION : To prevent loss of input power, ensure that the total maximum loads on the circuits
supplying power are within the current ratings of the wiring and breakers.
• Record your installation and configuration information as you work. See Appendix C, "Site Planning and
Maintenance Records," on page 159.
Use the following screw torques when installing the switch:
• Captive screws: 4 in-lb
• M3 screws: 4 in-lb
• M4 screws: 12 in-lb
• M6 screws: 20 in-lb
• 12-24 screws: 30 in-lb
• 10-20 screws: 22 in-lb
Attaching Bottom-Support Rails to a Two-Post Rack for the
SAN192C-6 Director
Use this procedure to attach the bottom support rails to a two-post rack for the SAN192C-6 Director.
Before you begin
Before you can install the bottom support rails for the chassis, you must do the following:
