Data Transmission Ranges; Power Cords - IBM SAN768B-2 Installation, Service And User Manual

QSFP ports are fixed speed 16 Gbps ports designed to be used with specialized
quad (4x16) connections and cables. They support only SWL.
The ports are universal and self-configuring, capable of becoming F_Ports (fabric
ports), FL_Ports (fabric loop enabled), or E_Ports (expansion ports).
The ports meet all required safety standards.

Data transmission ranges

Table 24 provides the data transmission ranges for different transceivers, cable
types, and port speeds.
Note: There is no LWL or ELWL version of the mSFP or QSFP transceiver.

Power cords

Two power cords for connecting between the SAN768B-2 and the power
distribution units on the 2109 C36 cabinet are shipped with the product. Two
additional power cords are provided if the optional upgrade power supply feature
is ordered (Feature Code 7880). See the IBM TotalStorage SAN Cabinet 2109 Model
C36 Installation and Service Guide for information on connecting the cabinet to the
facility power source. If the stand-alone feature is ordered for the SAN768B-2, then
