Recommended Tools

• When performing any type of work on the PS6610 array, including inserting and removing disk
drives, you should always wear a wrist grounding strap (not provided) to protect the hardware
from electrostatic discharge. See
• To lock and unlock the drawers on the array, you will need a T20 Torx key (provided).

Hardware Protection

When handling array hardware, use an electrostatic wrist strap (not included) or a similar form of
protection to protect your PS Series array from electrostatic discharge. To use a wrist strap:
1. Connect the steel snap on the coil cord to the stud on the elastic band. See
2. Fit the band tightly around your wrist.
3. Connect the band to ground. You can either plug the banana connector into a matching grounded
receptacle, or attach it to the matching alligator clip and connect the clip to a grounded device.
Examples of an appropriate ground would be an ESD mat or the metal frame of a grounded piece
of equipment.

Shutting Down and Restarting an Array

The PS6610 array includes redundant, hot-swappable drives, power supplies, and control modules.
You can remove a redundant component without affecting operation as long as a functioning
component is available. Otherwise, Dell recommends that you cleanly shut down the array and turn
off power before removing a component.
Note: When an array is shut down, any volumes with data on the array will be set offline until the
array is successfully restarted. Being offline affects initiators that are connected to the volumes.
