Cleaning the System

Warning: Do not insert any metal object, such as a screwdriver, or place your hand into an open slot or the backplane when the E-series router is on. Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. These actions prevent electric shock and serious burns.

Caution: When cleaning the system, wear an antistatic wrist strap connected to the system's ESD grounding jack. This action helps to protect modules from damage by electrostatic discharge.

Dust is attracted to the side of the system on which the air intake vent is situated. Clean this side of the system with a dry cloth every few weeks to prevent excessive accumulation of dust. This cleaning will maintain the efficiency of the cooling system and prevent damage to electronic components.
