Communication over the IP Network

The service processor runs Java Console server configured as the TCP/IP socket
7787. Access over the IP network is possible via the 3746-9x0 network node IP,
FC 5033 (TIC3, port 2080), the 3745 (using the TIC2), the MAE, or via a bridge or
router connected to the service ring.

Point-to-Point Protocol Communication

The service processor runs the point-to-point protocol (PPP) server over the
communication port 1 (COM 1) connected to an asynchronous modem for remote
links. The remote controlling workstation communicates with the service processor
via the PPP server using a switched line.

Security Features

Java Console security features include:

Enabling and Configuring Java Console in the MOSS-E

Java Console is enabled and configured in the SP Customization menu of the
MOSS-E.
IP addresses for the PPP server and client are required for communicating with the
service processor and NNP(s) over a switched line. You are also required to
customize several passwords.
Note: The management password is required to define or modify Java Console
passwords.

Using DCAF to Remotely Log On to the Service Processor

PS/2 (or equivalent) workstations can remotely access the service processor
MOSS-E and CCM functions through DCAF, an IBM licensed program. A DCAF
session allows the user to either:
DCAF enables the remote workstation to operate as a controlling workstation and
the service processor to operate as a target workstation. When a DCAF session is
established between a remote workstation and a service processor, the user of the
remote workstation can perform MOSS-E functions as though seated before the
service processor.

Remote Workstations (Consoles)

There are five types of remote workstation (console). These types define how the
workstation is connected to the service processor.
