Compaq ProLiant BL e-Class System Overview and Planning 29
Positioning PDUs in 22U, 36U, and 42U Racks
The position of the PDUs in the rack side panels depends on the rack size, the number of ProLiant
BL e-Class server blade enclosures deployed in the rack and the cable management solution. As a
general rule, install PDUs from the bottom to the top of the rack.
Cabling Guidelines
• Do not block airflow of center fans or power supplies with large cable bundles.
• Do not block access to power supply handles. Leave enough cable slack so the power
supplies can be removed without having to disconnect cables.
• Do not block access to the fan cage. Leave enough cable slack so the fan cage can be
extended without having to disconnect cables. All fans should be physically accessible
for service.
• Shorter cables help reduce cable clutter. For power cables, IEC C14 to IEC C13 (10A)
cables are available in various lengths as follows:
142257-001 (x1) IECC13-C14, 2m WW
142257-002 (x1) IECC13-C14, 2.5m WW
142257-003 (x1) IECC13-C14, 3m WW
142257-004 (x1) IECC13-C14, 3.6m WW
142257-005 (x1) IECC13-C14 Right Angled, 3.6m WW
142257-006 (x1) IECC13-C14, 1.4m WW
142257-007 (x15) IECC13-C14, 1.4m WW
