2.2 Service Access
The bottom of lowest of the five system chassis must be mounted no lower than
2.95 in. (75 mm) above the bottom of the rack or cabinet to enable removal and fitting
of the orange sacrificial lifting handle.
Ensure that units or cables above a Sun Fire B1600 blade system chassis do not
protrude beyond the front face of the system chassis to enable proper airflow.
Access to the front and back of the Sun Fire B1600 blade system chassis is required
for installation and system maintenance.
Note – If you are installing the system chassis into a cabinet that has a door, you
might need to swing the door back 180 degrees, or remove the door altogether.
