Maintaining E-Series Routers

Storing Modules and Components

Caution: Failure to store electronic modules and components correctly may lead to damage of these items.

Retain the packaging in which a module or component was shipped, and use this packaging to store the item. Modules are shipped in antistatic bags and protective packaging. Components, such as transceivers and NVS cards, are shipped in antistatic plastic containers within an antistatic padded box.

Follow these guidelines for storing modules and components:

•Store each module in a separate antistatic bag.

•Store components in an antistatic plastic container. Some of these containers can accommodate several components in separate compartments.

•Do not store multiple modules or components in an antistatic bag or container where they can touch other items.

•(Optional) Store the item in its antistatic bag or container within the protective packaging or padded box that the item was shipped in.

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.
