Cabling and powering up the system 39
WARNING: Be sure that all circuit breakers are locked in
the off position before connecting any power components.
Cabling the management modules
The server blade management modules and power management modules are
cabled together in daisy-chain fashion to provide the management link. Each
management module has two management link connectors: one to connect to
enclosures above and one to connect to enclosures below. Cabling the
management modules enables the system to identify rack topology for power and
data management.
CAUTION: Do not install NIC cabling or telephone cabling into
the management link connectors; these devices are not supported.
When deploying the HP BladeSystem 1U Power Enclosure and attached server
enclosure into an existing installation, it is necessary to upgrade all management
module firmware on all enclosures to the latest version.
Management cabling guidelines
Observe the following guidelines for cabling the management modules.
