Using the service port connection
The Onboard Administrator service port is the enclosure link-up connector which also has a laptop icon next
to the up arrow. When the enclosure link connectors are used to link enclosures, the top enclosure link-up
connector will be the Service Port for all the linked enclosures. This port is a 100BaseT Ethernet jack and may
be directly connected to a laptop or PC RJ45 Ethernet connector using a standard CAT5 patch cable as the
wiring on the link-up connector is crossed over to allow direct connect to a PC 100BaseT connector.
The Service Port provides direct connection to any of the active Onboard Administrator modules in all linked
enclosures or just the active Onboard Administrator module in a single enclosure if there are no other linked
enclosures. The network connection is private to the enclosures and cannot be used to access any device
outside the internal enclosure management network. It can be used to directly access the active Onboard
Administrator at the active service IP address, found on that enclosure Insight Display, Enclosure Info screen.
The laptop or PC connected to the enclosure service port must have DHCP enabled its network connection,
and obtains a zero-conf IP address in the range 169.254.x.y after a DHCP timeout if the laptop or PC is
running windows. If the laptop or PC is running Linux, you might have to manually set the network port to
169.254.2.1 with a netmask of 255.255.0.0.
To access an active Onboard Administrator GUI—Use the active OA service IP address from the Insight
Display on that enclosure as the web address in your laptop or PC browser. Log into the OA with a
configured user account and password.
To access an active Onboard Administrator CLI—Use a Telnet or SSH program based on the configured
network access settings and connect to the active OA service IP address. Log into the OA with a configured
user account and password.
