Communication ports

The communication ports, which are located on the network board, include a serial port, ethernet port, and redundant ATM uplink port.

Serial port

The serial port connects the Passport 8250 device to a local host using a RS-232 cable. Using a standard terminal emulation software application running on the local host, you can directly access the command line interface (CLI).

Use the serial port to configure the Passport 8250 device for operations before the Passport 8250 device is connected to your network.

Ethernet port

The ethernet port connects the Passport 8250 device to a local area network (LAN) using a RJ-45 cable.You can use a Telnet session on a remote host to remotely access the CLI, provided the Passport 8250 device already has an Internet protocol (IP) address.

Use the ethernet port to configure the Passport 8250 device while the Passport 8250 device is connected to your network and to communicate with other devices within your network.

Redundant ATM uplink port

The ATM uplink port connects the Passport 8250 device to the ATM network using a STM-1/OC-3 single-mode or multi-mode fiber optic cable. The ATM uplink port has two physical connectors and one connector is configured as the primary port that listens for incoming signals from the ATM network.

Dual power supply modules

The Passport 8250 device uses two field-replaceable 10 amps, -10 V DC power supply modules. Each power supply module has a 3w3-D connector and independent power feed.

If a power supply module fails, the Passport 8250 device can operate temporarily using one power supply module and one power supply filler pack.

Fan module

A field-replaceable fan module cools the internal components of the Passport 8250 device.
