The rack or cabinet should be adequately secured to prevent it
from becoming unstable and/or falling over.
Devices installed in a rack or cabinet should be mounted as low as
possible, with the heaviest devices at the bottom and progressively
lighter devices installed above.
For safe operation do not install the switch with the back of the
switch (with the fan vents) facing either downward or upward.
Do not wall mount the 2626-PWR or the 2650-PWR switches.
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, ensure 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. If the PWR device's supplied power cord does
not fit, contact HP.
When installing the switch, 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. 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), if using a 2600 switch, or 50 °C
(122 °F) if using a 2600-PWR switch.
Ensure the air flow around the sides and back of the switch is not
restricted. Leave at least 7.6 cm (3 inches) for cooling. If this unit is placed
in a fully-enclosed rack make certain the ambient temperature inside the
rack near the switch does not exceed 55 °C (if using a 2600 switch) or
50 °C (if using a 2600-PWR switch).
