6 Hardware Maintenance
The device is designed as a modular chassis and allows you to order any module as a
Field Replacement Unit (FRU). This section describes the procedures for installing or
replacing modules.
Warning: Maintenance service of this device must be made only by qualified service
personnel in restricted access locations and connected to an earthed power socket.
Note: Ensure that all unoccupied module chassis slots are covered with blank panels.
This allows optimal internal airflow pressure within the chassis.
6.1 Prerequisites
Before performing any maintenance procedures, read this section.
6.1.1 Grounding the Device
Before performing any maintenance procedures, ensure that your device is properly
grounded.
6.1.2 Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) due to improper handling of the device's modules and
components can cause irreversible damage to the equipment. Adhere to the following
guidelines for preventing ESD:

When handling 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 a
grounded workstation or computer chassis.

To prevent static electrical damage to the module, do not touch the electrical
components of the module. Instead, hold the module only on the edges where no
electrical components are located.

Ensure that the modules are securely installed in the chassis.

To attach an ESD wrist strap to the chassis:
1. Attach the ESD wrist strap to your body (typically, the wrist) so that it is in direct
contact with your skin.
2. Attach the other end of the wrist strap (e.g., an alligator clip) to a grounded workstation
or computer chassis.
