NOTE: If only QFX5110-48S switches are available, cable and configure
the switches as a QFX5110 Virtual chassis.
QFX5110-48S Hardware
As shown in Figure 1 on page 5, the QFX5110-48S is a 10-Gigabit Ethernet enhanced
small form-factor pluggable plus (SFP+) switch with 48 SFP+ ports and four 100-Gbps
quad small form-factor (QSFP) pluggable solution (QSFP28) ports. Each SFP+ port (0
through 47)can operate as a native 10-Gigabit Ethernet port or a 1-Gigabit Ethernet port
when 1-Gigabit Ethernet optics are inserted.
Each QSFP28 port (48 through 51) can operate as a native 100-Gigabit Ethernet port, a
native 40-Gigabit Ethernet port, or as4 independent 10-Gigabit ports when using breakout
cables. The four QSFP28 ports can be used as either access ports or as uplinks. The
QFX5110-48S provides an aggregate throughput of 960 Gbps. The QFX5110-48S has a
1 U form factor and comes standard with redundant fans and redundant power supplies.

QFX5110-32Q Hardware
As shown in Figure 2 on page 6, the QFX5100-32Q is a flexible configuration switch
allowing either 32 ports of 40-Gigabit Ethernet quad small form-factor pluggable plus
(QSFP+) or 20 ports of QSFP+ and 4 ports of high-density 100-Gigabit Ethernet quad
small form-factor pluggable solution (QSFP28). Each QSFP+ port can operate as a
native 40-Gigabit Ethernet port, or as four independent 10-Gigabit Ethernet ports when
using breakout cables. The four QSFP28 ports are available either as access ports or as
uplinks.
Of the 32 QSFP+ physical ports, 20 ports are available for 10-Gigabit Ethernet
channelization. For full details on the different port channelization modes, see
“QFX5110-32Q Port Panel” on page 12. The QFX5110-32Q switch provides an aggregate
throughput of 1.28 Tbps.
