5.5 Update Channel
The Update Channel Interface is provided by the Ethernet Switch and is physically implemented
using one DXAUI port. The DXAUI port is directly connected to Zone 2 connector P20 row 4
(Update Channel Port 0-1) and connector P20 row 3 (Update Channel Port 2-3). E-Keying for
the Update Channel is guaranteed via 98CX8234 Ethernet Switch, which disables its ports after
power-up reset and enables individual ports only by configuration.
5.6 Serial Redirection
Terminal Server is implemented to provide serial redirection into base network for serial
consoles of SP and both Packet Processors. The Terminal Server functionality is implemented
using routing logic implemented in the Glue Logic FPGA plus an additional Microcontroller.
The Microcontroller converts the incoming UART ports from Glue Logic FPGA into an Ethernet
interface, which is connected to the Ethernet Switch. For the connection between
Microcontroller and Switch, Marvell 88E1512, Gigabit Ethernet Transceiver in 100Base-T mode
is used.
