Fan Trays - Aruba 8360 Series Installation And Getting Started Manual

Fan Trays

The Aruba 8360 48Y6C switch is equipped with five field-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. Non-8360
48Y6C SKUs identified in this document are equipped with three field-replaceable, hot-swappable fan trays.
Port-to-Power Airflow (Fan Tray): JL714A

Power-to-Port Airflow (Fan Tray): JL715A

In the event of missing fan trays, misconfigured airflow direction, and/or faulted fans, the switch will try to
maintain adequate cooling by increasing fan speeds and/or disabling misconfigured devices. If adequate cooling
cannot be maintained, the switch will power off for five minutes before rebooting and assessing cooling
capabilities.
Fan trays and power supplies installed in an 8360 switch must have the same cooling air flow direction (port-to-
power or power-to-port). Air flow direction in an 8360 switch is not controlled by software. To change the air flow
direction, replace the power supplies and fan trays with power and fan tray units supporting the air flow direction
required.
For all SKUs (excluding 8360-48Y6C,) a minimum of two working fan trays is required for operation. If fewer than
three working fan trays are detected, the Global status, Rear status, and corresponding Fan Tray LEDs will FLASH
amber. For the 8360-48Y6C, a minimum of four working fan trays is required for operation. If fewer than five
working fan trays are detected, the Global status, Rear status, and corresponding Fan Tray LEDs will FLASH amber.
The system will automatically shut down if overheating is detected.
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 for five minutes and then reboot to reassess cooling capabilities.
System airflow direction (Port-to-Power or Power-to-Port) is configured automatically at system initialization and
cannot be reconfigured by the user. System airflow 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 conflicting airflow 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 airflow.
Red release latch indicates Port-to-Power airflow.

Blue release latch indicates Power-to-Port airflow.
