Hardware Maintenance

The device is designed as a modular chassis and allows you to order certain parts as a Field
Replacement Unit (FRU). This section describes the procedures for replacing these parts.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) due to improper handling of the device's Fan Tray or Power Supply
modules can cause irreversible damage. Therefore, adhere to the following guidelines for
preventing ESD:
■ When handling these modules, always wear a grounded ESD wrist strap or ankle strap at a
grounded work area to prevent ESD. Connect the equipment end of the strap to the
chassis' ground lug.
To prevent static electrical damage to a module, do not touch its electrical components.

ii.
DO NOT operate the device without the Fan Tray module.
Before replacing a failed Fan Tray module, make sure that you have the
replacement Fan Tray module on hand so that you can replace the module
immediately.
When removing the Fan Tray module, the fan blades may still be rotating at high
speeds (even if you power off the device). Therefore, partially extract the module
from the chassis and then wait a few seconds to allow the fan blades to stop, prior
to extracting the module entirely from the chassis.
N'opérez pas l'appareil sans module de Caisse de ventilateur ! Avant de
remplacer le module de Caisse de ventilateur, assurez-vous que vous avez le
module de remplacement en main.
Avant de retirer le module de Caisse de ventilateur et une fois l'appareil mis hors
tension, les lames risquent de continuer à tourner à grande vitesse. Aussi,
patientez quelques secondes pour permettre aux lames de s'arrêter, avant
d'extraire le module du châssis.
Loosen the two Philips-head, spring-loaded captive screws, which are located on
both sides of the Fan Tray cover.
Remove the Fan Tray cover.
