1 - MTP 1x12 fiber male connector
2 - Integrated 3 meter MTP cable
3 - Transceiver with pull-tab
Follow these guidelines for using QSFPs when connecting ICLs. Refer to“Installing
a QSFP transceiver” on page 65 to install cables and QSFP transceivers.
v The QSFP ports on the core switch blades can be used only with an inter-chassis
link (ICL) license. After the addition or removal of a license, the license
enforcement is performed on the ports only when the
portdisable and
portenable commands are issued on the ports. An ICL license must be installed
on all SAN512B-6 and SAN256B-6 switches forming the ICL connection. Up to
nine neighboring switches can be connected with the MTP cables.
v The 32 Gbps QSFP28 transceivers on SAN512B-6 core routing blades only
operate at 32 Gbps and cannot be configured at 16 Gbps for Fabric OS v8.0.1.
Therefore, you cannot connect an ICL between a 32 Gbps transceiver on a
SAN512B-6 core blade and a 16 Gbps QSFP transceiver on a SAN384B-2 or
SAN768B-2 core routing blade. You must connect between 16 Gbps transceivers
on each blade.
v An off-the-shelf MTP cable up to 100 meters can be used as an ICL cable when
using the standard SWL optics. The 2 km 16 Gbps QSFP with LWL optics has an
integrated 3 meter single-mode pigtail with a male MTP connector for
connectivity to a patch panel or female terminated MTP patch cable to achieve
up to 2 km distances.
v IBM supports fully populating a switch with ICL connections using a mixture of
50 and 100 m SWL optics and 16 Gbps 2 km LWL optics.
v Any number of ICL ports can be used for 2 km distances when using 2 km LWL
16 Gbps QSFPs and configuring 20 buffer credits per virtual channel. There are
no limitations on the number of ICL ports if all ICL distances are a few hundred
meters.
On the core routing blade faceplates, QSFP ports belonging to the same trunking
groups are indicated with the same color border under the ports. These colors are
also applied to the port map labels on each blade faceplate to indicate ports
belonging to the same trunking groups.
