Installing a DAE2P/DAE3P Requirements This section explains site and cabling requirements. Site requirements Power Cooling For proper operation, the installation site must conform to certain environmental specifications. These are detailed below and in Appendix A. To determine a enclosure's worst case power requirements, use the power rating on the enclosure label. This rating is the maximum power required for a fully loaded enclosure. The amount of internally regulated power that a maximum configuration requires from the power supplies and cooling system determines the values for input current, power (VA), and dissipation per disk enclosure. Typical values will be less depending on the number, manufacturer, and type of disk drives. These values represent the sum of the values shared by the line cords of two power supplies in the same enclosure. Power cords and supplies share the power load evenly. If one of the two power supplies fails, the remaining supply and cord support the full load. You must use a rackmount cabinet with AC power distribution, and have main branch AC distribution that can handle these values for the number of disk enclosures that you will interconnect. The temperature at the front bezel inlet must meet the ambient temperature specification described in Appendix A. The site must have air conditioning that can maintain the specified ambient temperature range. The air conditioning must be able to handle the BTU requirements of the DAE2P/DAE3P disk enclosures. Cabling requirements The DAE2P/DAE3P supports copper cable for a Fibre Channel connection to another Fibre Channel device (for example, a storage processor, DAE2, or another DAE2P/DAE3P). Any copper cables you use must meet the appropriate standards for 2-Gb FC-AL. Such cables are fully shielded, twin-axial, full-duplex cables with at least one High Speed Serial Data Connector - 2 (HSSDC2) connector (DAE2s and CX-series storage processors require HSSDC connections; CX3-series processors use SFP connectors). The DAE2P/DAE3P does not support cables shorter than 1 meter or longer than 10 meters. EMC supports and can provide 2-, 5-, and 8-meter cables. 2-2 DAE2P/DAE3P Hardware Reference

DAE2P/DAE3P Hardware Reference
Installing a DAE2P/DAE3P
Requirements
This section explains site and cabling requirements.
Site requirements
For proper operation, the installation site must conform to certain
environmental specifications. These are detailed below and in
Appendix A
.
Power
To determine a enclosure’s worst case power requirements, use the
power rating on the enclosure label. This rating is the maximum
power required for a fully loaded enclosure. The amount of internally
regulated power that a maximum configuration requires from the
power supplies and cooling system determines the values for input
current, power (VA), and dissipation per disk enclosure. Typical
values will be less depending on the number, manufacturer, and type
of disk drives. These values represent the sum of the values shared by
the line cords of two power supplies in the same enclosure. Power
cords and supplies share the power load evenly. If one of the two
power supplies fails, the remaining supply and cord support the full
load. You must use a rackmount cabinet with AC power distribution,
and have main branch AC distribution that can handle these values
for the number of disk enclosures that you will interconnect.
Cooling
The temperature at the front bezel inlet must meet the ambient
temperature specification described in
Appendix A
. The site must
have air conditioning that can maintain the specified ambient
temperature range. The air conditioning must be able to handle the
BTU requirements of the DAE2P/DAE3P disk enclosures.
Cabling
requirements
The DAE2P/DAE3P supports copper cable for a Fibre Channel
connection to another Fibre Channel device (for example, a storage
processor, DAE2, or another DAE2P/DAE3P).
Any copper cables you use must meet the appropriate standards for
2-Gb FC-AL. Such cables are fully shielded, twin-axial, full-duplex
cables with at least one High Speed Serial Data Connector - 2
(HSSDC2) connector (DAE2s and CX-series storage processors
require HSSDC connections; CX3-series processors use SFP
connectors). The DAE2P/DAE3P does not support cables shorter
than 1 meter or longer than 10 meters.
EMC supports and can provide 2-, 5-, and 8-meter cables.
