Additional information is listed here:
The 40Gbps QSFP+ slots can be used as either regular networking
ports or stacking ports with the VCStack feature.
When used as regular networking ports the 40Gbps QSFP+ slots
support 40Gbps transceivers or breakout cables, which convert the
slots into four 10Gbps ports.
The switches come with one pre-installed power supply. It is not
field-replaceable.

Chapter 1: Overview
Note
Additional information about the transceiver slots is given here:
They do not support 100Mbps transceivers.
They support full-duplex mode only.
SFP or SFP+ transceivers must be purchased separately. For a list of
supported transceivers, refer to the AT-x550-18XSQ data sheet on the
Allied Telesis web site.
40Gbps QSFP+
Transceiver Slots
The two QSFP+ transceiver slots support the following types of
transceivers:
AT-QSFPSR4 transceiver - 150m using multi-mode fiber optic
cable
AT-QSFPLR4 transceiver - 10k with single-mode fiber optic cable
AT-QSFP1CU and AT-QSFP3CU direct connect cables in lengths
of 1 and 3 meters, respectively
AT-QSFP-4SFP10G-3CU and AT-QSFP-4SFP10G-5CU breakout
cables in lengths of 3 and 5 meters, respectively
The QSFP+ slots are initially configured as stacking slots for the
VCStack feature. If you plan to use the switch as a stand-alone unit,
you can use the slots with transceivers as regular networking ports
by disabling the VCStack feature. The instructions are provided in
Chapter 6, “Configuring the Switch for Stand-alone Operations” on
page 85.
QSFP+ transceivers must be purchased separately. For a list of supported
transceivers, refer to the x550 product sheet on the Allied Telesis web site.

Chapter 1: Overview
Note
QSFP+ Transceiver Slots
The switches have two QSFP+ transceiver slots that support the following
types of 40Gbps transceivers:
AT-QSFPSR4 transceiver - requires 12-strand OM4 fiber optic
cable and has a maximum operating distance of 150m (492 ft).
AT-QSFPLR4 transceiver - requires single-mode fiber optic cable
and has an operating range of 2m (6.6 ft) to 10km (6.2 mi).
AT-QSFP1CU and AT-QSFP3CU direct connect cables in lengths
of 1 and 3 meters, respectively
AT-QSFP-4SFP10G-3CU and AT-QSFP-4SFP10G-5CU breakout
cables in lengths of 3 and 5 meters, respectively
You can use QSFP+ transceivers as standard networking ports or as
stacking ports for the VCStack feature.
The QSFP+ transceiver slots are initially configured as stacking
slots for the VCStack feature. You have to disable the VCStack
feature to use the transceiver slots as regular networking ports. For
instructions, refer to Chapter 6, “Configuring the Switch for Standalone Operations” on page 85. For instructions on how to install the
switches in a VCStack, refer to the x550 Series Installation Guide for
Virtual Chassis Stacking.
For a list of supported QSFP+ transceivers, refer to the x550 Series data
sheet on the Allied Telesis web site.
When the switch is operating as a stand-alone device and the VCStack
feature is disabled, the QSFP+ transceiver slots support the AT-QSFP4SFP10G-3CU and AT-QSFP-4SFP10G-5CU breakout cables. Refer to
Figure 4. A breakout cable converts a QSFP+ transceiver slot from one
40Gbps port to four 10Gbps ports. You have to disable the VCStack
feature on the switch to use the QSFP+ transceiver slots with breakout
cables.
Figure 4. QSFP+ to SFP+ Breakout Cable
The QSFP+ slots are numbered 17 and 21 on the front panel. Here are the
guidelines to port numbering:
24
x550 Series Installation Guide for Stand-alone Switches
A QSFP+ transceiver in slot 17 has the port number 17.
A QSFP+ transceiver in slot 21 has the port number 21.
The four 10Gbps transceivers on a breakout cable in slot 17 have
the port numbers 17, 18, 19, and 20.
The four 10Gbps transceivers on a breakout cable in slot 21 have
the port numbers 21, 22, 23, and 24.

Chapter 1: Overview
Note
eco-friendly Button
The eco-friendly button on the front panel of the switch is used to toggle
the port LEDs on or off. You might turn off the LEDs to conserve electricity
when you are not monitoring the device. You can also toggle the LEDs
with the ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in
the Global Configuration mode of the command line interface of the
AlliedWare Plus management software. The switch is said to be operating
in a low power mode when the LEDs are turned off.
Operating the switch in the low power mode with the LEDs turned off does
not interfere with the network operations of the device.
The management software on the switch has a command that blinks the
LEDs so that you can quickly and easily identify a specific unit among the
devices in an equipment rack. It is the FINDME command. The command
works on the switch even if you turned off the LEDs with the eco-friendly
button or NO ECOFRIENDLY LED command.
The Switch ID LED is always on, but it displays different information
depending on whether the LEDs are on or off. When the LEDs are on, the
ID LED displays the ID number of the switch. When the switch is operating
in the low power mode with the LEDs off, the ID LED indicates whether the
switch is a stand-alone unit or the master or member switch of a VCStack,
as detailed in Figure 10 on page 33.
Before checking or troubleshooting the network connections to the
ports on the switch, you should always check to be sure that the
LEDs are on by either pressing the eco-friendly button or issuing the
ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in
the Global Configuration mode of the command line interface.

VCStack Feature
Note
x550 Series Installation Guide for Stand-alone Switches
You can use the switches as stand-alone units or join multiple units
together with the QSFP+ transceiver slots and the VCStack feature. The
switches of a VCStack act as a single virtual unit. They synchronize their
actions so that switching operations, like spanning tree protocols, virtual
LANs, and static port trunks, span across all of the units and ports. Two
advantages of stacks are listed here:
You can manage multiple units simultaneously, which can simplify
network management.
You have more flexibility in how you configure some of the
features. For instance, a static port trunk on a stand-alone switch
can consist of ports from the same switch. In contrast, a static trunk
on a stack can have ports from different switches in the same
stack.
This guide explains how to install the devices as stand-alone units.
For instructions on how to install the switches in a VCStack, refer to
the x550 Series Installation Guide for Virtual Chassis Stacking.
