Cards
This chapter describes the Cisco 7600 Series Ethernet Services 20G (ES20) line cards. It contains the
following sections:
• Cisco 7600 Series Ethernet Services 20G Line Cards, page 13-1

• Cisco 7600-ES20-GE Line Card LEDs, page 13-2
Cisco 7600 Series Ethernet Services 20G Line Cards
The Cisco 7600 Series Ethernet Services 20G (ES20) line cards are a multiple-fabric, fixed-port Ethernet
line card for the Cisco 7600 series routers that are capable of 20 Gbps of traffic forwarding using a fixed
port interface design. The two versions of the Cisco 7600 Series Ethernet Services 20G line card are:
• 2-port version: 7600-ES20-10G
• 20-port version: 7600-ES20-GE
The difference between the two versions are the link interface daughter cards that accept small form-factor
pluggable (SFP or XFP) optical transceivers. Additionally, each of the two versions has a packet engine
daughter card and a control processor daughter card.
The SFP and XFP modules allow the line cards to be configured for different media types (copper or fiber)
and different optical requirements (single mode fiber or multimode fiber) as available.
The 7600-ES20-10G uses a 2-port 10GE fixed interface daughter card that accepts pluggable XFP modules.
The 7600-ES20-GE uses a 20-port GE fixed interface daughter card that accepts pluggable SFP modules.
For information on configuring features supported on the ES20 line cards, refer to the Cisco 7600-ES20
Ethernet Line Cards Configuration Guide. For information on installing the ES20 line cards, see the
Cisco 7600-ES20 Ethernet Line CardsHardware Installation Guide.
Cisco 7600-ES20-10G Line Card LEDs
The Cisco7600-ES20-10G line card has three LEDs, as shown in Figure 13-1. There is one Status LED
and two A/L (Active Loopback) LEDs. Table 13-1 provides LED descriptions.
