The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the general equipment, safety, and site preparation requirements for installing the Cisco ASR 1000 Series Fixed Ethernet Line Cards. This chapter contains the following sections:
You need the following tools and parts to remove and install the Cisco ASR 1000 Fixed Ethernet Line Card. If you need additional equipment, contact a Cisco service representative.
This section provides safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, might harm you. A warning symbol precedes each warning statement.
Follow these basic guidelines when working with any electrical equipment:
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. The Cisco ASR 1000 Series Fixed Ethernet Line Cards comprise printed circuit boards that are fixed to metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of these carriers. Although the metal carriers help to protect the boards from ESD, use a preventive antistatic strap when handling the line cards.
The following are the guidelines for preventing ESD damage:
An optical single-mode transmitter uses a small laser to transmit the light signal to the network ring. Keep the transmit port covered whenever a cable is not connected to it. Although multimode transceivers typically use LEDs for transmission, it is a good practice to keep open ports covered and avoid staring into open ports or apertures. The single-mode aperture port contains a laser warning label, as shown in Figure 2-1. The multimode aperture contains a Class 1 LED warning label, as shown in Figure 2-1. These warnings apply to SFP and XFP modules that transmit signals via an optical carrier signal.
