Installing the 5400zl Switches
Installation Procedures
Installation Precautions (continued)
C a u t i o n s
If you are installing any of the X2 transceivers the operating ambient temperature
should not exceed 40C (104F). See transceiver specifications in Appendix A 
If the switch is to be shipped in a rack, use only an HP 10000 series rack
and a rail mounting kit (5070-0145) for each switch.
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. Each power supply should be connected to a dedi-
cated branch circuit to prevent tripping building circuit breakers. 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 55C (131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.
