DANGER
Hazardous voltage, current, or energy levels are present inside any
component that has this label attached. Do not open any cover or barrier
that contains this label.
(L001)
Each power supply can be connected to a separate AC circuit to mitigate the risk of
down time during a power failure. When used in a redundant configuration, the dual
power supplies have a load-sharing capability that enables each power supply to
operate at approximately 50% of full load. Using redundant power can minimize the
power disruption during a power supply failure and extend the expected lifetime of
each power supply by operating normally in a conservative power mode.
There is no power switch on the RackSwitch; the switch unit powers up when
power is supplied through the power cords.
The Power Supply LED indicates the status of the power supplies. The LED flashes
when only one power cord is connected, and is steady when both power cords are
connected.
Switch ports
The RackSwitch switch ports and port options are described in the following
sections.
QSFP+ ports
Sixteen 40 GbE QSFP+ ports are located on the front panel. These ports accept
supported optical QSFP+ transceivers or direct attach cables (DACs). The
supported transceivers interoperate with any 40GBASE-SR4 compliant device, and
support distances up to 100 meters on OM3 fiber. Transceivers must be purchased
separately.
QSFP+ ports enable you to make one 40 GbE connection, or four 10 GbE
connections, using a breakout cable. QSFP+ optical transceiver with MTP-to-4 LC
(SFP+) fiber breakout cable. This option supports only BLADE 10GBASE-SR SFP+
transceivers. The 40GBASE-SR4 specification (802.3ba-2010) indicates a higher
optical power level than standard 10GBASE-SR. SFP+ SR transceivers can handle
the higher optical power levels.
QSFP+ to four 10 GbE SFP+ breakout DAC. The SFP+ connectors on supported
breakout DACs are labelled A, B, C, and D, which correspond to the first, second,
third, and fourth ports in the port range.
For the available QSFP+ transceivers and DACs for the switch, see
