LightStream 1010 ATM Switch Processor Module Configuration Note 5
ASP Description
Enet Port
The Ethernet RJ-45 port (labeled Enet) may be used to connect a management workstation and
enables SNMP management of the LightStream 1010 switch. (See Figure 5.)
Dual PCMCIA Card Slot
The dual-height Personal Computer Memory Card International Association (PCMCIA), Type II,
card slot (shown in Figure 5) can be used to store Cisco Internetwork Operating System (IOS)
software or system configuration information on a Flash card. The switch may also boot from the
software stored on the Flash card.

Console Port Signals
The console port on the ASP is a female, EIA/TIA-232, data communications equipment (DCE),
DB-25 receptacle. Both data set ready (DSR) and data carrier detect (DCD) are active when the
system is running. (See Figure 6.) The ready to send (RTS) signal tracks the state of the clear to send
(CTS) input. The console port does not support modem control or hardware flow control. The
console port requires a straight-through EIA/TIA-232 cable. Table 1 lists the signals used on this
port.
Table 1 Console Port Signals
Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a
standard by the Electronic Industries Association (EIA) and Telecommunications Industry
Association (TIA).
