Power Supplies
The S55 and S60 chassis are designed to support two hot-swappable power
supplies with integrated fans that provide the cooling for the chassis. There are
two types of power supplies (AC or DC) and there are two air-flow directions
(Normal and Reversed). Two power supplies are required for full redundancy,
but each system will operate with a single power supply.
• In the S55, a blank panel must be attached as redundant power supplies are
not installed.
• In the S60, one of the power supply bays can be equipped with a fan only
module.
WARNING: To prevent electrical shock, make sure the system is grounded
properly. If you do not ground your equipment correctly, excessive emissions
may result. Use a qualified electrician to ensure that the power cables meet
your local electrical requirements.
Fans
The chassis come from the factory with the following:
• The S55 comes with 1 power supply and 2 fan modules installed in the
chassis.
• The S60 comes with 1 power supply and 1 fan module installed in the
chassis.
Both the fan modules and the integrated fan-power supply are hot-swappable if
a second (redundant) power supply is installed and running. With redundant
power supplies, traffic will not be interrupted if a fan module is removed.
Task S60
Attach the connectors to the both DC
power units at the rear of the S60,
making sure that the connection is
secure.
Replace the plastic cover over the DC
connectors.
Turn the power switch on.
