Brocade ICX 6650 features
The Brocade ICX 6650 is an Ethernet switch for campus LAN aggregation and classic Ethernet data center Top of Rack (ToR)
environments.
The Brocade ICX 6650 is a high-density aggregation switch that oers both 1/10 and 10/40 Gigabit Ethernet (GbE) line rates, low
latency cut-through switching, and 1600 Gbps switching capacity for campus LAN and classic Ethernet data center environments.
The Brocade ICX 6650 features:
• Comprehensive support for a range of 10GbE and 40GbE optics (refer to the Brocade Ethernet Optics Family datasheet on
the Brocade website).
• Dual redundant, hot-swappable 250 W AC or 510 W DC power supplies available with intake or exhaust airow.
• Dual redundant, hot-swappable fan units available with intake or exhaust airow.
• One Gigabit Ethernet port (RJ-45) and one serial management port to congure and manage the switch through the CLI.

Ports on Demand licensing
The Brocade ICX 6650 features Ports on Demand licensing. With Ports on Demand licensing, software features do not require licenses
and you can add port licenses as needed.
A fully populated device supports 56 front-panel, dual-speed 1/10 GbE SFP+ ports, 4 rear-panel 40 GbE QSFP+ ports, and 2 rear-
panel 4x10 GbE QSFP+ breakout ports.
You can purchase and install Ports on Demand licenses in blocks of eight dual-speed 1/10 GbE SFP+ on the front-panel ports. These
ports are grouped sequentially, enabling ports 33 through 40, 41 through 48, and 49 through 56. To enable the additional front-panel
ports, you must purchase and install an ICX6650-8P10G-LIC-POD license.

You can purchase and install up to three ICX6650-2P40G-LIC-POD licenses to enable pairs of 40 GbE ports or 4x10 GbE breakout
ports on the rear panel. An ICX6650-2P40G-LIC-POD license can be applied to any of the following pairs of 40 GbE rear-panel ports
or 4x10 GbE breakout ports:
• 2/1 and 2/2 40 GbE rear-panel ports
• 2/3 and 2/4 40 GbE rear-panel ports
• 3/1-4 and 3/5-8 4x10 GbE rear-panel breakout ports
NOTE
You can add an ICX6650-2P40G-LIC-POD license to any
conguration.

2. 2/4
3. 3/1-8: 4x10 GbE breakout ports (3/1-4, 3/5-8)
The breakout ports support one of the following options:
• Direct-attached QSPF+ to 4 SFP+ copper breakout cables (Part number 40G-QSFP-4SFP-C-/0101/0301/0501)
• Breakout-capable SR4 QSPF+ optical transceiver (Part number 40G-QSFP-SR4-INT)
No trial licenses are available with Ports on Demand licensing.
Brocade ICX 6650 slot and Ethernet port numbering
Many CLI commands require users to enter port numbers as part of the command syntax, and many show command outputs display
port numbers. The port numbers are entered and displayed in stack-unit/slot number/port number format. In all Brocade ICX 6650
inputs and outputs, the stack-unit number is always 1.
The Brocade ICX 6650 contains the following slots and Ethernet ports:
• Slot 1 is located on the front of the Brocade ICX 6650 switch and contains ports 1 through 56, which are 1/10 GbE SFP+
ports. Refer to the following gure.

1. Slot 1
• Slot 2 is located on the rear of the Brocade ICX 6650 switch and contains ports 1 through 3 on the top row and port 4 on the
bottom row. These ports are 40 GbE QSFP+ ports. Refer to the following gure.
NOTE
The QSFP+ 40 GbE LR4 optical transceiver is supported in ports 1 and 2 only. When the module is inserted into a stack-unit/
slot number/port number combination that is not 1/2/1 or 1/2/2, the following error message displays: “QSFP LR-4 optics
not supported on port port-number.”

3. Slot 3
• Slot 3 is located on the rear of the Brocade ICX 6650 switch and contains ports 1 through 8. These ports are 4x10 GbE
breakout ports and require the use of a breakout cable. Refer to the previous gure.
Supported transceivers and cables
The Brocade ICX 6650 supports the following transceivers and cables:
• 1 GbE
– SX
– LX
– Copper
• 10 GbE
– SFP+: USR, Short Reach, Long Reach
– Active twinaxial copper (1 meter, 3 meter, and 5 meter)
– 10 GbE ER SFP+

18 Part Number: 53-1003621-04

– 40 GbE (SR4) QSFP+ transceiver with breakout to 4x10 GbE up to 100 meters on OM3 ber
– 40 GbE direct attach (DAC) copper breakout (1 meter, 3 meter, and 5 meter)
– 40 GbE QSFP to QSFP active twinaxial (1 meter, 3 meter, and 5 meter)
– 40 GbE (LR4) QSFP+ transceiver up to 10 km
NOTE
Non-branded active twinaxial cables can be used, but Brocade does not support them.
Breakout cables
The rear panel of the Brocade ICX 6650 contains two 4 x 10 GbE ports which support QSFP+ to 4 SFP+ (4 x 10 GbE) direct-attach
copper breakout cables. These cables are terminated with optical connectors and are available in 1m, 3m, 5m, and greater lengths. No
additional connectors or cabling are required for these ports.
We do not support 40G passive (optical) cables.

Cooling system and fans
The fans cool the CPU, main memory, and voltage regulators. For Brocade ICX 6650 switches, the fans use either:
• An exhaust airow which moves air from front to back. Refer to the rst gure below. Devices with exhaust airow are labeled
with a green arrow with an “E.”
• An intake airow which moves air from back to front. Refer to the third gure below. Devices with intake airow are labeled with
an orange arrow with an “I.”
CAUTION
Ensure that the airow direction of the power supply unit matches that of the installed fan tray. The power supplies and fan
trays are clearly labeled with either a green arrow with an "E", or an orange arrow with an "I."
