10 LightStream 1010 ATM Switch Processor Module Configuration Note
Preparing Network Connections
Ethernet Connection Equipment
You need an Ethernet cable with RJ-45 male connectors (see Figure 8) between the Ethernet port
and the Ethernet network. See the ASP Ethernet RJ-45 connector information in the section “Enet
Port” in the chapter “LightStream 1010 ATM Switch Hardware” in the LightStream 1010 ATM
Switch User Guide.

EIA/TIA-232 Connections
EIA/TIA-232 supports unbalanced circuits at signal speeds up to 64 kbps. The ASP console
connection is a standard 25-pin D-shell connector (known as a DB-25) that is commonly used for
EIA/TIA-232 connections. Figure 9 shows the connectors at the local end of the adapter cable. The
system console port on the ASP EIA/TIA-232 connection supports only asynchronous connection.

Console Port Connection Equipment
The ASP contains an EIA/TIA-232 asynchronous console port (DB-25 receptacle).
When connecting a serial device, consider the cable as an extension of the switch for an external
connection; therefore, use null-modem cable to connect the switch to a remote DCE device such as
a modem or DSU. A straight-through cable to connect the switch to a DTE device such as a terminal
or PC.
Before you connect a terminal to the console port, configure the terminal to match the switch console
port, as follows:
• 9600 baud
• 8 data bits
• No parity
• 1 stop bit
