N2125 SAS/SATA HBA for IBM System x Hardware User’s Guide
March 2013 N2125 SAS/SATA HBA for IBM System x Hardware User’s Guide
N2125 SAS/SATA HBA for IBM System x Certifications and Safety Characteristics
5.4 Connectors
This section describes the different connectors on the HBA. See Figure 1 for connector locations.
PCIe Connector (EC1). The HBA supports a x8 interface. The PCIe host interface connection is through the edge
connector (EC1), which provides connections on both the top (EC1B) and bottom (EC1A) of the board. The signal
definitions and pin numbers conform to the PCIe specification.
SAS Connectors (J10 and J11). The HBA supports SAS connections through connectors J10 and J11, which are
SFF-8088 mini-SAS, external connectors.
5.5 Power Requirements
The maximum power requirements for the HBA under normal operation are as follows:

PCIe 12.0 V = 1.3 A

Passive cable power values
—
Nominal = 9.8 W
—
Worst case = 16.0 W
5.6 Thermal and Atmospheric Limits
The atmospheric limits for the HBA are as follows:

Temperature range: 0°C to 55°C (32°F to 131°F) (dry bulb)

Relative humidity range: 5 percent to 90 percent noncondensing

Maximum dew point temperature: 32°C (89.6°F)

Minimum airflow: 200 linear feet per minute
The following limits define the storage and transit environment for the HBA:

Temperature range:
−
45°C to +105°C (
−
49°F to +221°F) (dry bulb)

Relative humidity range: 5 percent to 90 percent noncondensing

Characteristics
The HBA meets or exceeds the requirements of UL flammability rating 94V-0. Each bare board is marked with the
supplier’s name or trademark, type, and UL flammability rating. Because these boards are installed in a PCIe bus slot,
all voltages are less than the SELV 42.4-V limit.
The design and implementation of the HBA minimizes electromagnetic emissions, susceptibility to radio frequency
energy, and the effects of electrostatic discharge.
The HBA meets the following integrated electromagnetic interference (EMI) compliance labels:

CE mark

CISPR Class B

C-Tick mark

Canadian Compliance Statement

FCC Class B, marked with the FCC Self-Certification logo

Japan VCCI
