2.4 Power Cord Specifications
A power cord is not supplied with the EX-3524/EX3548 switch. Use only a correctly rated power cord certified (as
appropriate) for the country of operation.
2.4.1 Power Protection
• If possible, use a circuit dedicated to data processing equipment. Commercial electrical
contractors are familiar with wiring for data processing equipment and can help with the load balancing
of these circuits.
• Install surge protection. Be sure to use a surge protection device between the electricity source and
the EX-3524/EX-3548 switch.
• Install an Uninterruptible Power Supply (UPS). A UPS provides continuous power during a power
outage. Some UPS devices have integral surge protection. UPS equipment requires periodic maintenance
to ensure reliability. A UPS of the proper capacity for the data processing equipment must be purchased.
