"Input/output ports". Power cord Mouse Keyboard USB 1 USB 2 Serial B Parallel Serial A Ethernet Video Input/output ports This section provides information about the input/output (I/O) ports on the server. These ports include the following: v One parallel port v One video port v One keyboard port v One auxiliary pointing-device (mouse) port v Two serial ports v Two Universal Serial Bus (USB) ports v One Ethernet port v One communication connector dedicated to the system management adapter Notes: 1. You can set an administrator password through the Configuration/Setup Utility program only if the optional system management adapter is installed in the server. 2. The Devices and I/O Ports choice appears only on the full Configuration/Setup Utility menu. If you have set both levels of passwords (user and administrator), you must type the administrator password to access the full Configuration/Setup Utility menu. Parallel port The server has one parallel port. This port supports three standard Institute of Electrical and Electronics Engineers (IEEE) 1284 modes of operation: Standard Parallel Port (SPP), Enhanced Parallel Port (EPP), and Extended Capability Port (ECP). Viewing or changing the port assignments You can use the Configuration/Setup Utility program to configure the parallel port as bidirectional; that is, so that data can be both read from and written to a device. In bidirectional mode, the server supports the ECP and EPP modes. Installing options 67

Input/output ports
This section provides information about the input/output (I/O) ports on the
server. These ports include the following:
v
One parallel port
v
One video port
v
One keyboard port
v
One auxiliary pointing-device (mouse) port
v
Two serial ports
v
Two Universal Serial Bus (USB) ports
v
One Ethernet port
v
One communication connector dedicated to the system management adapter
Notes:
1.
You can set an administrator password through the Configuration/Setup Utility
program only if the optional system management adapter is installed in the
server.
2.
The
Devices and I/O Ports
choice appears only on the full Configuration/Setup
Utility menu. If you have set both levels of passwords (user and administrator),
you must type the administrator password to access the full
Configuration/Setup Utility menu.
Parallel port
The server has one parallel port. This port supports three standard Institute of
Electrical and Electronics Engineers (IEEE) 1284 modes of operation: Standard
Parallel Port (SPP), Enhanced Parallel Port (EPP), and Extended Capability Port
(ECP).
Viewing or changing the port assignments
You can use the Configuration/Setup Utility program to configure the parallel port
as bidirectional; that is, so that data can be both read from and written to a device.
In bidirectional mode, the server supports the ECP and EPP modes.
