(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.
Power specifications
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 red48 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.
Table 25. Power specifications
Specification Value
Input voltage Range: 85 - 264 VAC Auto-volt, Nominal:
100 to 240 VAC (auto-sensing)
Input frequency Range: 47-63 Hz; Nominal: 50 - 60 Hz
Inrush current Limited to 60A peak for any initial current
surge or spike of 10 ms or less at either cold
or warm start . Any additional inrush
current surges or spikes in the form of AC
cycles or multiple AC cycles greater than 10
ms, and less than 150 ms, must not exceed
15A peak.
Power supply output (each) Low line (85- 132 VAC), 1000W; High line
(180 - 264 VAC), 2000W
The power requirements for a given configuration depend on which blades have
been installed in the chassis. Table 26 on page 151 shows the power draw for the
