The following items provide additional information:
 The 40Gbps QSFP+ slots 17 and 21 can be used as regular
Ethernet networking ports or stacking ports with the VCStack
feature. The default setting for the ports is VCStack stacking ports.
To use the ports as regular Ethernet networking ports, you need to
disable the VCStack feature or designate other ports as stacking
ports.
 When used as regular networking ports the 40Gbps QSFP+ slots
can support either 40Gbps transceivers or breakout cables, which
convert the ports into four 10Gbps ports.
 The switches come with one pre-installed power supply. It is not
field-replaceable.
Twisted pair ports 1 to 16 on the AT-x550-18XTQ Switch have these
features:
 1Gbps or 10Gbps operation
 100 meters (328 feet) maximum operating distance per port
 Auto-Negotiation for speed
