Planning Ethernet LAN Connections

The Connectrix service processor provides for dual Ethernet support
via two Ethernet adapter cards. Dual Ethernet support isolates all
network traffic between the service processor and the switch
directors on the private Connectrix network. This reduces the burden
on the customer's network, and safeguards the directors from
unauthorized access.
CAUTION
!
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.
Figure 5-10 on page 5-27 depicts a typical dual Ethernet
configuration.
Link to Connectrix The Connectrix service processor is linked to managed ED-140Ms,
Cabinet
ED-64Ms, and/or DS-xxMs in Connectrix cabinets through the
10Base-T Ethernet LAN in the Connectrix cabinet. This interface is the
10 Mb/s Ethernet adapter card located in the top PCMCIA card slot
on the left side of the P88-series service processors or at the left rear
corner of the A5000 series service processors. All Connectrix
management functions of the switches are performed via this LAN
when the swithes are configured to reside on the private ethernet
LAN inside the Connectrix cabinet. This is the factory default
configuration and it is recommended to keep the switches on this
private Ethernet network.
Recommendation EMC strongly recommends installing the Connectrix cabinet(s) on a
dedicated 10Base-T Ethernet LAN segment, in order to avoid the
security and traffic problems common to public LANs.
Link to Customer Data The Connectrix service processor can be linked to the customer data
Network
network through the 10/100 Base-T Ethernet adapter card located in
the bottom PCMCIA card slot on P88 series service processors or the
10/100 3COM PCMCIA card located on the right side of A5000 series
service processors. This is the Ethernet network on which managed
servers, storage devices, and other end devices may reside; it is also
the network accessed by Connectrix remote user workstations.
