2.6 Powering On

Figure 24. Power Cord Connector

DataDirect Networks recommends that you use an uninterruptible power supply (UPS) to

protect your enclosure.

Using the included power cords, connect each APC unit to an AC power source (Figure 24).

Power-On Sequence

NOTE :

Once RAID arrays are configured, the enclosures should be powered on first

and allowed to complete drive spin-up and discovery prior to powering on

the hosts. Discovery is complete once the drive LEDs stop flashing.

If you are using a single enclosure configuration, the installation is complete and you can

begin using your SS2460 by turning on the power switch on each APC unit.

If you are using an expanded configuration, ensure that all expansion (secondary) SS2460

are powered on before powering on the primary SS2460 (the primary SS2460 is the one

connected directly to the hosts). This is required for the system to properly ‘see’ the

expansion SS2460.

Power-Off Sequence

NOTE :

Once RAID arrays are configured on the enclosures, the hosts should be

shut down prior to powering off the enclosures.

If you are using a single SS2460 configuration (primary SS2460 only), you can power down

the SS2460 by turning off the APC units.

If you are using an expanded configuration, ensure that the primary SS2460 is powered off

first, then the secondary SS2460.
