NOTE: For supported transceivers, see the latest version of the ArubaOS-Switch and ArubaOS-CX
Transceiver Guide.
Split mode (QSFP28)
QSFP ports on the Aruba 8360 switch series are capable of operating as:
• 100G ports
• 40G ports
• Split into 4 individual 25G or 10G ports
Chapter 2 Introducing the switches 9

When operating as a 100G/40G port, all 4 port indicator LEDs will blink in unison for Link/Activity or Mode
behavior, see LED behavior. When in split mode, each of the 4 LEDs corresponds to one of the split ports,
1-4, left to right, respectively.
NOTE: QSFP28 ports on the 48XT4C (JL706A/JL707A) do not support split mode and can only
function at 100G or 40G speeds.
Management ports
Console Port
Aruba 8360 switches include an RJ-45 serial console port on the rear of the switch. This port is used to
connect a console to the switch by using an RJ-45 serial cable (not supplied). A DB9-to-RJ-45 console cable
can be ordered from HPE: JL448A, Aruba X2C2 RJ45 to DB9 Console Cable.
The 8360 switches also include a USB-C console port on the front of the switch. This port can be used to
connect a console to the switch by using a standard USB-C cable (not supplied). The USB-C port has
precedence for input. If both cables are plugged in, the console output is echoed to both the RJ-45 and the
USB-C ports, but the input is only accepted from the USB-C port.
NOTE:
• Use of the USB-C port may require the installation of a standard USB driver. New Windows
installs include the driver by default.
• USB driver available from Aruba: https://support.arubanetworks.com/ToolsResources/
tabid/76/DMXModule/514/Default.aspx?EntryId=7512
For more information on the console connection, see Setup for initial conguration. The console can be a
PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.
The Aruba CX mobile app and the Aruba USB Bluetooth adapter enable you to congure your switch from
your mobile device. For information about using the Aruba CX mobile app to congure the switch, see the
Fundamentals Guide for your switch and software release.
Out-of-band management (OOBM) port
This RJ-45 port is used to connect a dedicated management network to the switch. To use it, connect an
RJ-45 network cable to the management port to manage the switch through Telnet from a remote PC or a
UNIX workstation.
To use this port, the switch must have an IP address. IP settings can be congured through a console port
connection or automatically from a DHCP/Bootp server.
A networked out-of-band connection through the management port allows you to manage data network
switches from a physically and logically separate management network.
For more information, see the Fundamentals Guide for your switch.
USB-A Aux port
The USB-A port is used for le management, downloading switch software or use of Aruba accessories. This
port uses a USB Type-A connector.

Console port (RJ-45)
The RJ-45 console port is used for CLI serial port access.
NOTE: RJ-45 and USB-C console ports provide CLI serial port access. The system will output to
both consoles simultaneously, but the system will only accept input from one console port. If
both RJ-45 and USB-C are connected, USB-C has priority.
Power supplies
The Aruba 8360 switch does not have a power switch; it is powered on when at least one installed power
supply is connected to an active AC power source. The power supplies automatically adjust to any voltage
between 100-127 and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings required.
Chapter 2 Introducing the switches 17

NOTE: Never insert or remove a power supply while the power cord is connected. Verify that
cord has been disconnected from the power supply before installation or removal.
The Aruba 8360 switch power supplies adapt electrical power for use with the switch. The chassis has two
slots that can hold individual power supplies to support load sharing, redundancy, and fault tolerance. Two
550W color coded power supplies are available for use with Aruba 8360 switches. A red release latch
indicates an Port-to-Power cooling air ow. A blue release latch indicates a Power-to-Port cooling air ow.
CAUTION: System airow direction (Port-to-Power or Power-to-Port) is congured automatically
at system initialization and cannot be recongured by the user. System airow direction is
determined by the power supply type installed in PS1 at initialization time (or PS2 if PS1 is
absent or faulted). Any Fan tray or Power supply of conicting airow type will be disabled by
the system. Ensure only matching fan trays and power supplies are used at any given runtime.

Guide

The Aruba 8360 switch is shipped with two hot-swappable, eld-replaceable, AC power supplies. Each power
supply has a country-specic power cord for connection to an AC power outlet. The switch can operate with
one active power supply.
Power supply instructions
WARNING: For indoor use only. The switch, AC power cord and all connected cables are not
designed for outdoor use.
WARNING: During installation, ensure that AC power is NOT connected to the power supply
being installed.
CAUTION: Shock hazard. To completely remove power from the switch, disconnect all power
cords.
IMPORTANT: For important safety, environmental, and regulatory information, see Safety and
Compliance Information for Server, Storage, Power, Networking, and Rack Products, available at
http://www.hpe.com/support/Safety-Compliance-EnterpriseProducts

Load sharing
Load sharing occurs when two power supplies are installed in the switch and turned on. Load sharing
divides the total power load of the switch among both power supplies.
Chapter 2 Introducing the switches 19

Redundancy
With power redundancy, the Aruba 8360 switch can continue normal operation even when one power
supply fails or is powered o. When two power supplies are installed, if one becomes unavailable (fails, is
powered o or removed) the remaining power supply provides full power for the device.
Even though the switch will run with one power supply removed, for thermal integrity reasons it is highly
recommended to not remove a failed power supply, until the replacement can be installed.
Hot swapping
Hot swapping allows you to replace one failed power supply while the other provides full power. This makes
it unnecessary to shut down the switch during the replacement procedure.
NOTE: If both power supplies are faulted, missing and/or use miscongured airow direction,
the system will shut down for ve minutes due to insucient cooling.
CAUTION: Never insert or remove a power supply while the power cord is connected. Verify
that the cord has been disconnected from the power supply before installation or removal.
Fan trays
The Aruba 8360 switch is equipped with three eld-replaceable, hot-swappable fan trays. Each fan tray
features individual fans that pull air through the chassis from Port-to-Power or Power-to-Port.
• Port-to-Power Airow (Fan Tray): JL714A
• Power-to-Port Airow (Fan Tray): JL715A
NOTE: In the event of missing fan trays, miscongured airow direction, and/or faulted fans, the
switch will try to maintain adequate cooling by increasing fan speeds and/or disabling
miscongured devices. If adequate cooling cannot be maintained, the switch will power o for
ve minutes before rebooting and assessing cooling capabilities.
CAUTION: Fan trays and power supplies installed in an 8360 switch must have the same cooling
air ow direction (port-to-power or power-to-port). Air ow direction in an 8360 switch is not
controlled by software. To change the air ow direction, replace the power supplies and fan
trays with power and fan tray units supporting the air ow direction you require.
CAUTION: A minimum of two working fan trays are required for operation. The system will
automatically shutdown if overheating is detected. If fewer than 3 working fan trays are
detected, the Global status, Rear status and corresponding Fan tray LEDs will FLASH amber.
CAUTION: If one fan tray is missing for more than two minutes the system will shutdown. If two
or more fan trays are missing, the system will shutdown immediately.
CAUTION: System airow direction (Port-to-Power or Power-to-Port) is congured automatically
at system initialization and cannot be recongured by the user. System airow direction is
determined by the power supply type installed in PS1 at initialization time (or PS2 if PS1 is
absent or faulted). Any Fan tray or Power supply of conicting airow type will be disabled by
the system. Ensure only matching Fan trays and Power supplies are used at any given runtime.
Fan trays are color-coded for Port-to-Power or Power-to-Port cooling airow.
• Red release latch indicates Port-to-Power airow.
• Blue release latch indicates Power-to-Port airow.
