Ethernet Interface Processor (Eip) - Cisco 7000 Hardware Installation And Maintenance

Figure 1-13
Following are the functions of the CIP LEDs.
•
Enabled—Indicates that the CIP has been enabled for operation by the system.
•
Present—Indicates that the adapter (ECA or PCA) has been detected by the CIP.
•
Loaded—Indicates that the adapter (ECA or PCA) firmware has been completely loaded.
•
Signal—For the ECA, this LED indicates that the Sync signal has been detected.
For the PCA, this LED indicates that the Operational Out signal has been detected. Note that
although a system reset and selective reset both cause the Operational Out signal to drop, the
signal LED will still be on during those sequences.
•
Online—For the ECA, this LED indicates that an establish-logical-path request has been
received from the channel.
For the PCA, this LED indicates that the PCA is ready to establish connection to the host channel.

Ethernet Interface Processor (EIP)

The EIP, shown in Figure 1-14, provides two, four, or six high-speed (10 Mbps) Ethernet ports. Each
port supports both Ethernet Version 1 and IEEE 802.3/Ethernet Version 2 interfaces. A bit-slice
processor provides a high-speed data path between the EIP and other interface processors. The
default EIP microcode resides on a ROM in socket U101. As with the other interface processors, the
Enabled LED lights to indicate that the EIP is enabled for operation. For complete descriptions of
the LED states refer to the appendix "Reading LED Indicators." LEDs indicate the following per
port:
•
Receive—Frames are being received.
•
Transmit—Frames are being transmitted.
