AT-AR026 4ETH PIC

The AT-AR026 4ETH PIC provides four 10BASE-T/100 BASE-TX auto-
negotiating ports. The ports have RJ-45 connectors and provide wire speed
unmanaged layer 2 switching.
AT-AR026 4ETH PICs are not recommended for use in AT-AR040 NSM PIC
bays because performance of these interfaces is likely to be reduced and packet
loss may occur.

Left Lit when the port is operating at 100Mbps and full duplex.
Right Lit when a link has been established. Flashing when data is being transmitted
through the port.
The AT-AR026 PIC includes a switch chip that switches independently of the
switch, router, or NSM that the PIC is installed in. The show interface
command will show each correctly installed AT-AR026 as a single interface.
The 10/100 "front side" Ethernet ports will not be shown.
AT-AR026 features include:
■
Five integrated switch ports with physical layer transceivers—four 10/100
Ethernet switch ports, and one fixed 10 Mbps port acting as the PIC to base
unit connector
■
128 kbytes of frame buffering SRAM
■
1.4 Gbps high performance memory bandwidth
■
10BASE-T and 100BASE-TX modes of operation
■
LED indicators for link, activity, full/half duplex, and port speed
■
Hardware based 10/100, full/half duplex, flow control, and auto-
negotiation
