By installing two power supply modules on the SV Director Server, the hot-swap
feature allows you to replace a failed power supply without interrupting the
appliance operation. During this hot-swap replacement, a maximum of two
minutes is recommended.

AC Power Supply Safety Considerations
Ensure all power connections conform to the rules and regulations in the
National Electrical Codes (NECs), as well as local codes. Follow these
precautions and recommendations when planning power connections to your
appliance:
National Electrical Codes (NECs), as well as local codes. Follow these
precautions and recommendations when planning power connections to your
appliance:
Check the power at your site before installation and periodically after
installation to ensure that you are receiving clean power (free of spikes and
noise). Install a power conditioner if necessary.

The AC power supply includes the following features:
- Auto selects either 110-V or 220-V operation.
- All units include an electrical cord. (A label near the power cord indicates

Warning!
This product relies on the building’s installation for short-circuit
(overcurrent) protection. Ensure that fuse or circuit breaker no larger than 120
VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors
(all current-carrying conductors). Statement 13

Cable Management
Cable management is the most visual aspect of your server setup. However,
cable management is often overlooked because it can be time consuming.
cable management is often overlooked because it can be time consuming.
Equipment racks and enclosures house more equipment today than ever before.
This growth has increased the need for organized cable management both inside
and outside the rack. Poor cable management not only leads to damaged cables
or increased time for adding or changing out cables, but also blocks critical
airflow or access. These problems can lead to inefficiencies in the performance
of your equipment or even downtime.
