Replacing a power supply and fan assembly
Complete the following steps to replace a combined power supply and fan assembly in a Brocade 6510.
CAUTION
The power supply switch must be in the off position when you insert the power supply into the
chassis. Damage to the switch can result if a live power supply is installed.
1. Ensure that the new power supply and fan assembly has the same part number and airflow label (or
lack thereof) as the power supply and fan assembly being replaced.
CAUTION
Ensure that the airflow direction of the power supply unit matches that of the installed fan
tray. The power supplies and fan trays are clearly labeled with either a green arrow with an
"E", or an orange arrow with an "I."
2. Orient the new power supply and fan assembly with the captive screw on the right, as shown in the
figure.
Do not force the installation. If the FRU does not slide in easily, ensure that it is correctly oriented
before continuing.
CAUTION
Carefully follow the mechanical guides on each side of the power supply slot and make sure
the power supply is properly inserted in the guides. Never insert the power supply upside
down.
3. Gently push the power supply and fan assembly into the chassis until it is firmly seated.
4. Using the Phillips screwdriver, secure the power supply and fan assembly to the chassis by
tightening in the captive screw.
5. Plug the power cord in to the power supply and fan assembly and power on the unit by pressing the
AC power switch to the I symbol.
