IBM SAN768B-2, Installation, Service And User Manual

Page: 158 / 186

The base unit SAN768B-2 comes with two power supplies. If the port blades
contain from 192 up to 384 16Gb ports plus QSFP ICLs, then four power supplies
are required.
Environmental requirements
Table 23 lists the environmental operating ranges for the SAN768B-2. The
requirements for non-operating conditions are also provided for acceptable storage
and transportation environments.
CAUTION:
For CA residents only: IBM recommends installing this product in a room size
of 2190 cubic feet (62 cubic meters) or larger at 0.4 ACH ventilation rate to
reduce the concentrations of any chemicals emitted by the product.

Note: The 0° to 40° Celsius range applies to the ambient air temperature at the air
intake vents on the nonport side of the SAN768B-2. The temperature inside
the system can be up to 75° Celsius during operation. If the internal
temperature range exceeds the operating ranges of the components, the
LEDs, error messages, and Fabric Watch alerts will indicate a problem. Use
the
tempShow
command or Fabric Watch commands to view temperature
status.
Fibre channel port specifications
The Fibre channel ports in the SAN768B-2 support full duplex link speeds at 2, 4,
8, 10, or 16 Gbps inbound and outbound, automatically negotiating to the highest
common speed of all devices connected to the port.
The ports are compatible with optical SWL (short wavelength: approximately 850
nm), and optical LWL (long wavelength: approximately 1310 nm) SFP+s and
mSFPs (FC8-64 only). The strength of the signal is determined by the type of SFP+
or mSFP. The mSFPs support only SWL.
