Supply power and power up the system

Supply power to the S55 after they are mounted in a rack (or on a table) and the optional modules are

installed.

Dell Force10 recommends re-inspecting your system prior to powering up. Verify that:

• the equipment is properly secured to the rack and properly grounded.

• the equipment rack is properly mounted and grounded.

• the ambient temperature around the unit (which may be higher than the room temperature) is within the

limits specified for the S55.

• there is sufficient airflow around the unit.

• the input circuits are correctly sized for the loads and that sufficient over-current protection devices are

used.

• all protective covers are in place.

• blank panels are installed if optional modules are not installed.

• blank panels are installed if redundant power supplies are not installed.

NOTE: A US AC power cable is included in the shipping container for powering up an AC power supply. All

other power cables must be ordered separately.

WARNING: Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an

ESD-preventive wrist or heel ground strap when handling the S55 and its components.

Power up sequence

When the chassis powers up, the fans immediately come on at high speed. The fan speed slows as the

system boots up.

The PWR LED blinks until the boot-up sequence is complete. When the boot up is complete the PWD

LED is steadily lit.

The Stack ID LED displays a digit to show the position of the unit in a stacking chain. For a single

chassis, a 0 displays.

AC power

Connect the plug to each AC receptacle, making sure that the power cord is secure.

As soon as the cable is connected between the S55 and the power source, the chassis is powered-up; there

is no on/off switch.
