Applying AC power
Before you apply AC power to the SAN256N director, take the following precautions:
• Verify that the site is set up to provide full AC power redundancy. Two separate,
independent power lines with two separate circuit breakers are required for a single
chassis (SAN256N director-16). An uninterruptible power supply (UPS) should be
connected to the redundent power source.
• Verify that the SANC40 cabinet is properly grounded according to local electrical
codes.
• Verify that AC power can be shut down quickly in case of an emergency. You should
have easy access to the AC input power connections.
• Verify that the supplied power cables are of adequate length and are correct for the
site. Refer to Appendix B. AC power reference on page 123 if the power cables do not
appear to be correct.
Attention: Refer to safety notices before starting the installation.
