SAN768B-2 Installation, Service, and User Guide
(FC8-64 only), and QSFPs (FC16-64 only). The strength of the signal is determined
by the type of SFP+, mSFP, or QSFP. The mSFPs and QSFPs support only SWL.
The QSFP transceiver part numbers supported on the core blades are different
from the QSFP transceiver part numbers supported on the FC16-64 port blade.
They are not interchangeable.
v QSFP ports on the core blades are fixed speed 16-Gbps ports designed to be
used with specialized quad (4x16) connections and cables. They support only
SWL.
v QSFP ports on the FC16-64 port blades can run at 4, 8, or 16-Gbps port speeds to
be used with quad-SFP connectors and cables. However, all the four ports in a
QSFP should be configured to run at the same port speed.
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.
DANGER
Multiple power cords. The product might be equipped with
multiple power cords. To remove all hazardous voltages,
disconnect all power cords. (L003)
The power subsystem is a redundant +48 V dc power distribution system with a
provision for up to four 2000-watt, 48V dc bulk power supplies. Bulk power
supplies produce the intermediate distribution voltage in the distributed power
system.
Table 25 shows the basic power specifications for each power supply.
