Cabling and powering up the enclosure 55
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 ("Enclosure Settings screen" on page 66) screen.
2. Connect the laptop or PC 10/100Mb Ethernet port configured for DHCP addressing to the available
link-up port on the top enclosure in the rack using a standard CAT5 patch cable. A Windows PC
automatically obtains an IP address. If no IP address is obtained, configure the PC Ethernet port for static
addressing using the IP address 169.254.1.254 with a netmask of 255.255.0.0.
3. Open a web browser on the PC and enter the active Onboard Administrator module Service IP address
found in the Enclosure Info screen in step 2.
4. Log into the Onboard Administrator. For more information on using Onboard Administrator, see the HP
BladeSystem Onboard Administrator User Guide.
Cabling the network to the enclosure
Cable the interconnect modules to the enclosure. See "Mapping to interconnect ports (on page 43)" and the
supporting documentation that came with your interconnect modules for specific details on cabling the
interconnect modules.
