Connecting Ethernet cables to the node canisters
On systems, the control enclosure has several Ethernet ports present or optionally
present on the rear of each node canister. Ports 1 and 2 provide access to system
management facilities. Ports 1, 2 and 3 on the rear of each canister can also provide
iSCSI connectivity and IP replication.
Procedure
To install the Ethernet cables, complete the following steps.
1. Connect Ethernet port 1 of each node canister in the system to the IP network
that will provide connection to the system management interfaces, as shown in
Figure 130. This port can also be used for iSCSI connectivity to the system by
hosts on the network. Where more than one control enclosure is present in the
system, ensure port 1 of every node canister is connected to the same network
to provide access if the configuration node fails.
2. Optionally, connect Ethernet port 2 of each node canister in the system to a
second IP network that will provide redundant connection to the system
management interfaces, as shown by the lighter cable connection in Figure 130.
This port can also be used for iSCSI connectivity to the system by hosts on the
network. If there is more than one control enclosure in the system, ensure that
port 2 of every node canister is connected to the same network to provide
access if the configuration node fails.
3. Optionally, connect Ethernet port 3 of both node canisters in a system to the
networks that will provide extra iSCSI connectivity to the system.
Note: Do not connect the Ethernet technician port (labeled T) to a network
switch. The technician port must only be directly connected to a personal
computer when initializing a system or servicing a node.
