Enclosure link cabling

The Onboard Administrator link module contains two enclosure link ports to allow any active
Onboard Administrator module to access linked enclosures. On a standalone enclosure or upper
enclosure in a series of linked enclosures, the upper enclosure link-up port functions as a service port
for temporary connection to a PC with a CAT5 patch cable. It provides quick access to any Onboard
Administrator module, iLO 2, or interconnect module with Ethernet management ability.
The enclosure link-down port connects to the enclosure link-up port on the enclosure below it. The
enclosure link-up port connects to the enclosure link-down port on the enclosure above it. Linking the
enclosures enables the rack technician to access all the enclosures through the open link-up/service
port. If more c-Class enclosures are added to the rack, they can be linked through the open enclosure
link-up port on the upper enclosure or the link-down port on the bottom enclosure.
NOTE
The enclosure link ports are designed only to support c-Class
enclosures in the same rack. The enclosure link-down port on the
upper enclosure is the service port. The enclosure link-down port
on the bottom linked enclosure is unused.
IMPORTANT
The HP BladeSystem c-Class Enclosure link ports are not
compatible with the HP BladeSystem p-Class Enclosure link
ports.
