Aruba 9300-32D Switch Series | Installation and Getting Started Guide 24
n
Do not ship any switch in a rack without checking for restrictions in the latest Aruba Installation and
Getting Started Guide. Otherwise, you may void the switch warranty.
n
Ensure the power source circuits are properly grounded, then connect the switch to the power source by
using the power cord supplied with the switch. For more information on power cords, see
Power Cords on
page 48 .
n
When installing the switch, the AC outlet should be near the switch and be easily accessible in case the
switch must be powered off.
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. See the environmental operating temperature information in the
Environmental
Specifications on page 49 section of this guide.
n
Ensure that the switch does not overload the power circuits, wiring, and over-current protection. 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 for a device are usually printed near the device AC power connectors.
n
Do not block any ventilation openings on the front or rear of the switch.
n
Leave a minimum of 6 inches (15.24 cm) for cooling at the front and back of the switch. For the air flow
direction, see the
Fan Trays on page 19 section of this guide.
n
If a power supply or fan tray must be removed and reinstalled, wait at least 5 seconds before
reinstallation. Otherwise, damage to the switch may occur. The power supply needs this time to discharge
any retained power.
n
The transceiver slots support SFP, SFP+, QSFP+, QSFP28, and QSFP-DD transceivers.
n
For more information, see the latest version of this guide and the ArubaOS-Switch and ArubaOS-
CX Transceiver Guide.
Prepare the Installation Site
Cabling Infrastructure : Ensure the cabling infrastructure meets the necessary network specifications.
Installation Location : Before installing the switch, plan its location and orientation relative to other
devices and equipment:
n
In the front of the switch, leave a minimum of 6 inches (15.24 cm) of space for the twisted-pair and fiber-
optic cabling.
n
In the back of the switch, leave a minimum of 6 inches (15.24 cm) of space for the power cord.
Cooling air flow in Aruba 9300-32D switches is front-to-back or back-to-front, depending on configuration.
All fan trays and power supplies installed in an 9300-32D switch must have the same air flow direction. See
Fan Trays for further detail.
