Management Modules; Server Blade Management Module - HP BL20p - ProLiant - G2 Setup And Installation Manual

Cabling and Powering Up the System

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.
Management Cabling Guidelines
Observe the following guidelines for cabling the management modules.
On the server blade management module:
•
The upper management link connector connects to enclosures above the module.
•
The lower management link connector connects to enclosures below the module.
On the power management module:
•
The right management link connector connects to enclosures above the module.
•
The left management link connector connects to enclosures below the module.
Additional Guidelines for 42U Solution
Observe the following additional guidelines for configuring a full-rack 42U solution
with two pairs of mini bus bars:
•
You must set the power configuration switches to establish the two power zones.
Refer to the "Power Configuration Switches" section in Appendix D, "LEDs and
Switches."
•
You must cable the power management module in zone 2 (upper pair of mini bus
bars) to both adjacent server blade management modules, above and below. This
connection enables system management to establish a full-rack topology.
