Dual Ethernet The CCSI MCVX2 (Twinhead P88) Connectrix service processor
provides two Ethernet LAN connections via two Ethernet adapter
cards on the left side of the notebook PC.
The purpose of dual Ethernet adapter cards is to enable Connectrix
network users to isolate Connectrix devices from the data center
network, and to provide a single access point for managing multiple
directors in a Connectrix complex. This is accomplished by
dedicating one Ethernet connection (to the 10-Base-T Ethernet) to a
private Connectrix network, and the other connection (to the
10/100Base-T Ethernet) to the customer data network.
Dual Ethernet is only supported on the service processor. The
PCMCIA Ethernet adapters in the service processor must be installed,
configured, and used in a very specific manner for the two networks
to function properly.
In dual-Ethernet configurations:
• The top Ethernet adapter card must be used as the interface to the
private Connectrix network. This slot contains a Silicom 10 Mbps
Ethernet CardBus adapter card, and the factory default TCP/IP
configuration must remain intact (IP address = 10.1.1.1, subnet
mask = 255.0.0.0, default gateway=blank).
• The bottom Ethernet adapter card must be used as the interface to
the customer network. This slot contains a Silicom 10/100 Mbps
Fast Ethernet CardBus adapter card. The factory default IP
address for this interface (IP address = 192.168.0.0, subnet mask =
255.0.0.0
) must be modified in order for Connectrix to connect to
the customer data network. The IP address, subnet mask, default
gateway, and DNS servers can be configured manually or via the
DHCP
(dynamic host control protocol) tab in the TCP/IP
Properties dialog box accessible via the Windows NT Control
Panel.
Figure 1-2 on page 1-4 depicts a typical dual Ethernet configuration.
