Procedure: Accessing a canister using a directly attached Ethernet
cable
Use this procedure if you need to use a direct Ethernet connection to attach a personal computer to a
node canister to run the service assistant or to use the service CLI.USB key.
Perform this procedure if you are not authorized to use a USB key in your data center and when the
service address of your nodes cannot be accessed over your Ethernet network. This situation might occur
for a new installation where the default service IP addresses 192.168.70.121 and 190.168.70.122 cannot be
accessed on your network.
Note: Do not attempt to use a directly attached Ethernet cable to a canister that is active in a cluster. You
might disrupt access from host applications or the management GUI. If the node is active, use the
management GUI network configuration options to set the service IP to an address that is accessible on
the network.
Perform the following steps to access a canister using a directly attached Ethernet cable:
1. Connect one end of an Ethernet cable to Ethernet port 1 of the upper node canister.
Note: A cross-over Ethernet cable is not required.
2. Connect the other end of the Ethernet cable directly to the Ethernet port on a personal computer that
has a web browser installed.
3. Use the operating system tools on the computer to set the IP address of the Ethernet port that is used
in the previous step to 192.168.70.10.
4. Point your web browser to the service address.
v If you have connected to node canister 1, the upper canister, point your web browser from your
personal computer to https://192.168.70.121.
v If you have connected to node canister 2, the lower canister, point your web browser from your
personal computer to https://192.168.70.122.

6. Log in with the superuser password. The default password is passw0rd.
7. After the action completes, disconnect your personal computer and reconnect the node canister to the
Ethernet network.
8. Set the service address of the canister to one that can be accessed on the network as soon as possible.

Procedure: Reseating a node canister

Use this procedure to reseat a canister that is in standby mode or because a service action has directed
you.
Verify that you are reseating the correct node canister and that you use the correct canister handle for the
node you are reseating. Handles for the node canisters are located next to each other. The handle on the
right operates the upper canister. The handle on the left operates the lower canister.
1. Verify the cluster status LED on the node canister. If it is permanently on, the node is active. If the
node is active, no reseating is required.
