IBM SAN768B-2, Installation, Service And User Manual

Page: 42 / 186

v Read “Power specifications” on page 127 to plan for meeting power supply
standards before installing the chassis.
v
To ensure adequate cooling, plan to install the chassis with the port side facing
the aisle where exhaust air is released (usually called the service aisle). This
prevents the fans from pulling in heated exhaust air.
v Plan for managing the cables before you install the chassis. A fully populated
SAN768B-2 will have a large number of cables that must be carefully routed to
minimize problems with installation and replacement of components, and in
order to maintain the minimum bend radius required for optical cables. Refer to
“Managing cables” on page 42 for more specific information. You can manage
the cables in a variety of ways, such as:
– Routing the cables down through the cable management tray
– Routing the cables out either side of the chassis
– Routing the cables through the cable channels on the sides of the cabinet
– Using patch panels
v Ensure that the airflow in the vicinity of the SAN768B-2 is a minimum of 595
cubic meters per hour (350 cubic feet per minute).
v
Ensure that the air temperature that is measured at the blower inlet does not
exceed 40°C (104°F ) during operation.
Ordering the lift tool
Important
The lift tool is required only when you install an additional SAN768B-2 or
when you install or remove the SAN768B-2 from the cabinet.
The ordering procedures for the lift tool vary depending on your location. You
should direct questions about these procedures to your regional representative.
Note: The bridge tool (PN 18P5855), which is required for installation, is shipped
with a new or a replacement SAN768B-2. The bridge tool, when installed,
serves as a temporary ramp between the lift tool and the SAN768B-2 rails
that are installed in a C36 cabinet. You do not need to return the bridge tool
when you are finished with it.
