1.7.1 Maintaining Correct Airflow and Cooling

In addition to supplying power, the APC units maintain proper airflow and cooling within the

enclosure.

Because there are two APC units, the enclosure can continue to operate even if one APC unit

fails.

The cooling fans in each APC unit run on separate circuits from the power supply. If one

APC unit fails, its fans continue to run on power supplied by the other APC unit.

However, for proper enclosure operation and cooling, two APC units with fully-functional

fans must be installed at all times. The enclosure can run temporarily (for no more than five

minutes) with a single APC unit while you install a new one—you must install a second APC

unit

as quickly as possible

to maintain correct airflow and cooling.

CAUTION ! Once you have removed a failed APC unit, you must replace it within five

minutes or the enclosure may overheat and shut down to prevent

hardware damage. This type of shutdown is immediate—unexpected

loss of data access and permanent data loss may occur.

1.8 Connection and Configuration Options

This section describes the different connection options for your SS2460 enclosure.

NOTE :

Unless otherwise noted, the enclosures in all these configurations support

SAS or SATA disk drives, but not a combination of both.

1.8.1 Basic Configuration–Single Controller System

Connect your SS2460 enclosure to a SAS/SATA HBA or SAS/SATA RAID card in a single host

system (Figure 8).

StorageScaler 2460 Enclosure

As your storage space requirements change, you can upgrade and expand this basic

configuration.

NOTE :

In single I/O controller configurations the controller must be installed in Slot

A (on the left side of the enclosure as seen from the back of the enclosure).

To install or remove an I/O controller, see Section4.2.
