following steps:

Note: Before you begin this procedure, be sure you powered down the Scalar

LTFS Appliance (see Turning Off the Scalar LTFS Appliance on page 1).

1Label the cables so that you can reconnect them to the correct ports.

2Remove all power, SAS, Ethernet, and Fibre Channel cables from the back of

the Scalar LTFS Appliance.

3Hold the power button in at least 20 seconds to discharge all of the

condensers before opening the Scalar LTFS Appliance.
