Aruba 4100i Switch Series | Installation and Getting Started Guide
35
n
If your installation requires a different power cord than the one supplied with the switch, be sure that the cord is
adequately sized for the current switch requirements. In addition, be sure to use a power cord displaying the
mark of the safety agency that defines the regulations for power cords in your country/region. The mark is your
assurance that the power cord can be used safely with the switch. (JL818A only)
n
Do not ship any switch in a rack without checking for restrictions. Otherwise, you may void the switch warranty.
n
Ensure that the power source circuits are properly grounded. Then connect the switch to the power source by
using the power cord supplied with the switch (JL818A) or via the wire terminals provided (JL817A).
n
When installing the switch, ensure that the AC outlet is near the switch. Make it easily accessible in case the
switch must be powered off. (JL818A only)
n
Ensure that the power cord and network cables at the switch mounting location do not create a tripping hazard.
n
Do not install the switch in an environment where the operating ambient temperature exceeds its specification.
n
Ensure that the switch does not overload the power circuits, wiring, and over-current protection at your
installation site. To determine the possibility of overloading the supply circuits, add the ampere ratings of all
devices installed on the same circuit as the switch. Then compare the total with the rating limit for the circuit.
The maximum ampere ratings are printed on the device near the AC power connector (JL818A) or on the power
supply (JL817A).
n
Avoid blocking any ventilation openings on the sides, rear, or front of the switch.
n
Ensure that the air flow around the switch is not restricted. Leave at least 3 inches (7.6 cm) for cooling.
Installation Precautions and Guidelines
Review these environmental and enclosure guidelines before installation:
n
Proper ESD protection is required whenever you handle Aruba equipment. Installation and maintenance
personnel should be properly grounded by using ground straps to eliminate the risk of ESD damage to the
switch. Do not touch connectors or pins on component boards. Do not touch circuit components inside the
switch. When not in use, store the equipment in appropriate static-safe packaging.
n
When the switch is installed in an industrial enclosure, the temperature within the enclosure may be greater
than normal room temperature outside the enclosure. Ensure temperatures inside the enclosure conform to
device specifications detailed in Environmental Specifications.
n
The switch meets the voltage dips and interruptions requirements of IEC 61850-3 only when powered by a
redundant power supply configuration.
n
If you are responsible for the application of safety-related programmable electronic systems (PES), you need
to be aware of the safety requirements in the application of the system and be trained in using the system.
n
For better EMC performance, it is suggested to use S/UTP or SF/UTP cables for copper Ethernet ports. Refer
ISO/IEC11801 standard for details on S/UTP and SF/UTP.
