Installation preparation
Power supply monitoring
For enhanced monitoring, power supplies send information to the switch software about the type
(AC or DC, and airflow mode).
Installing the fan trays and power supply
Your switch supports a combination of field-replaceable power supplies and cooling fan trays. Two
fan trays are included with your switch. You must install the two fan trays and at least one power
supply before using the switch. The switch supports an optional second power supply for
redundancy and load sharing.
To install the fan trays and power supplies to your switch, use the following procedure.
Important:
Supported cooling airflow directions are: front to back or back to front. The airflow direction of
fan trays and power supplies are labelled and fixed. The fan trays and power supplies do not
support the ability to change their airflow direction. Avaya recommends that you install the first
power supply in PSU1 to determine the airflow direction.
Before you begin
Verify that the fan trays and power supply are compatible—ensure that the airflow direction for all
fans and power supplies match.
Procedure
1. Insert each fan-tray into a rear fan-tray slot.
2. Verify that each fan-tray is fully seated in the slot and secure each fan-tray with two thumb
screws.
3. Insert each power supply into a rear power supply slot.
If a blanking plate covers the required power-supply slot, remove the plate before inserting
the power-supply.
4. Verify that each power-supply is fully seated in the slot and securely clipped in place.
Example
The following figure shows how to properly insert the cooling fan trays and power supplies into your
switch.
