Installing the Switch 5300xl Series Cautions Installing the Switch 5300xl Series Installation Procedures Installation Precautions (continued) ■ Ensure the power source circuits are properly grounded, then use the power cord supplied with the switch to connect it to the power source. If your installation requires a different power cord than the one supplied with the switch and power supply, be sure the cord is adequately sized for the switch's current 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. The mark is your assurance that the power cord can be used safely with the switch and power supply. ■ When installing the switch, note that the AC outlet should be near the switch and should be easily accessible in case the switch must be powered off. ■ Ensure the switch does not overload the power circuits, wiring, and overcurrent protection. To determine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the switch and compare the total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near the AC power connectors. ■ Do not install the switch in an environment where the operating ambient temperature might exceed 40°C (104°F). ■ Allow three to four inches of space around the sides and back of the switch to make sure the air flow for the switch is not restricted. ■ Ensure that for any switch slot into which no module is installed, the cover plate is installed to cover the slot. A cover plate is required for safe operation, and to ensure proper switch cooling. For safety, you should never have more than one module slot uncovered at a time while the switch is powered on. ■ For safe and reliable operation, disconnect EPS cable before installing or removing J8161A modules. For more information refer to the ProCurve Switch xl Modules Installation Guide. 2-5

Installation Precautions (continued)
■
Ensure the power source circuits are properly grounded, then use the
power cord supplied with the switch to connect it to the power source.
If your installation requires a different power cord than the one supplied
with the switch and power supply, be sure the cord is adequately sized
for the switch’s current 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. The mark is your assurance that the
power cord can be used safely with the switch and power supply.
■
When installing the switch, note that the AC outlet should be near the
switch and should be easily accessible in case the switch must be
powered off.
■
Ensure the switch does not overload the power circuits, wiring, and over-
current protection. To determine the possibility of overloading the supply
circuits, add together the ampere ratings of all devices installed on the
same circuit as the switch and compare the total with the rating limit for
the circuit. The maximum ampere ratings are usually printed on the
devices near the AC power connectors.
■
Do not install the switch in an environment where the operating ambient
temperature might exceed 40
°
C (104

■
Allow three to four inches of space around the sides and back of the
switch to make sure the air flow for the switch is not restricted.
■
Ensure that for any switch slot into which no module is installed, the
