v Plan your site configuration and prepare the site before installing the switch. The
recommended site planning tasks are listed in the Site Planning and
Maintenance Records section.
v Ensure that there is adequate space around the switch to allow for servicing the
switch and for adequate airflow. The airflow requirements are listed the
Appendix A, “Product specifications,” on page 43 section.
v Ensure that you are positioning the switch in a rack so that it takes in cold air
from the cold aisle and sends out air to the hot aisle. For more information, see
the Airflow Considerations section.
v Ensure that the air-conditioning meets the heat-dissipation requirements listed in
the Appendix A, “Product specifications,” on page 43 section.
v Ensure that the cabinet or rack meets the requirements listed in the Cabinet and
Rack Installation section.
v Ensure that the chassis is adequately grounded. If the switch is not mounted on
a grounded rack, we recommend that you connect both the system ground on
the chassis and the site power ground to an earth ground.
v Ensure that the site power meets the power requirements listed in the
Appendix A, “Product specifications,” on page 43 section. If available, you can
use an uninterruptible power supply (UPS) to protect against power failures.
CAUTION:
Avoid UPS types that use ferro-resonant technology. These UPS types can
become unstable with systems such as the IBM Storage Networking SAN
c-type Family, which can in turn have substantial current draw fluctuations
because of fluctuating data traffic patterns.
v As you install and configure the switch, record the information listed in the Site
Planning and Maintenance Records section.
v Use the following screw torques when installing the switch.
Captive screws: 4 in-lb
M3 screws: 4 in-lb
M4 screws: 12 in-lb
10- 32 screws 20 in-lb
10- 32 screws 20 in-lb
12-24 screws: 30 in-lb
Installing the Switch
This section describes how to use the rack-mount kit to install the IBM SAN50C-R
switch into a cabinet or rack that meets the requirements described in the “Rack
Requirements” on page 29 section.
CAUTION:
If the rack is on wheels, ensure that the brakes are engaged or
that the rack is otherwise stabilized.
CAUTION:
If connecting a IBM SAN50C-R switch to a 110-VAC power
system, ensure that sufficient power is provided to meet the
chassis power requirements for the number of modules installed.
If the rack is on wheels, ensure that the brakes are engaged or
that the rack is otherwise stabilized.
