Cabling and powering up the enclosure 58
• Use the enclosure link-up port on the top enclosure for temporary connection to a PC using the enclosure
service port ("Cabling a PC to the enclosure service port" on page 58) to provide quick access to any
Onboard Administrator module, iLO, or interconnect module with Ethernet management ability.
• Allow enclosure settings to be shared between enclosures, which simplifies deployment of multiple
enclosures.
NOTE: The enclosure link ports are designed only to support c-Class enclosures in the same rack.
The enclosure link-up port on the top enclosure is the service port, and the enclosure link-down port
on the bottom linked enclosure is unused.
NOTE: If more c-Class enclosures are added to the rack at a later time, the open enclosure link-up
port on the top enclosure can be used to link the new enclosure.
NOTE: The HP BladeSystem c-Class enclosure link ports are not compatible with the HP
BladeSystem p-Class enclosure link ports.
To link the enclosures, use a standard Category 5 (CAT5) patch cable to connect the enclosure link-down port
on the first enclosure to the enclosure link-up port on the second enclosure.
Cabling a PC to the enclosure service port
A PC can be temporarily connected to the enclosure to access the Onboard Administrator modules, iLO, and
interconnect modules with Ethernet management ability. When enclosures in the same rack are linked,
connecting a PC to the service port enables you to access the Onboard Administrator modules, iLO, and
interconnect modules for all linked c-Class enclosures in that rack.
NOTE: The service port is the enclosure link-up port on the top enclosure in a group of linked
enclosures. If the enclosures are not linked together, each enclosure has a service port.
Only one PC at a time can be connected to a group of linked enclosures using the service port.
1. Use the Insight Display on the enclosure you are logging into to obtain the Service IP address of that
active Onboard Administrator module on the Enclosure Info screen. The Service IP address can be
found in the Enclosure Settings screen.
