CAUTION:
Forty-eight 10 GbE Small Form-factor Pluggable (SFP+) ports are located on the
front panel. These ports accept supported optical or copper SFP or SFP+
transceivers, or direct attach cables (DACs). Transceivers must be purchased
separately.
QSFP+ ports
Four 40 GbE Quad Small Form-factor Pluggable (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, as follows:
• QSFP+ optical transceiver with MTP-to-4 LC (SFP+) fiber breakout cable. This
option supports only NEC 10GBASE-SR SFP+ transceivers. The
40GBASE-SR4 specification (802.3ba-2010) indicates a higher optical power
level than standard 10GBASE-SR. BLADE 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.
Console Port
The RS-232 (mini-USB) serial console port is located on the front panel. The
following table describes the pinouts for the mini-USB port.
Table 1.
Console port pin assignments
The console cable provides an RJ-45 connector (see Table 2 for RJ-45 pin
assignments). A retention clip is available to secure the console connection.
The following table describes the pin assignments for the RJ-45 connector on the
console cable.
Data processing environments can contain equipment transmitting on system
links with laser modules that operate at greater than Class 1 power levels. For
this reason, never look into the end of an optical fiber cable or open
receptacle. (C027)
