IBM SAN512B-6, Installation, Service And User Manual

Page: 82 / 286

The following notes apply to QSFP transceivers on core routing blades.
v
You cannot connect an ICL between a 4x32 Gbps QSFP on a SAN512B-6 core
blade and a 16-Gbps QSFP on a DCX 8510 core routing blade. You must use a
4x16 Gbps QSFP on the SAN512B-6 blade.
v The 4x32 Gbps QSFP28 transceiver has four links that operate at 32 Gbps to
achieve a 128 Gbps link speed. The 4x16 Gbps QSFP+ transceiver has four links
that operate at 16 Gbps to achieve a 64 Gbps link speed. The cables come in
specific predetermined fixed lengths that are qualified by IBM.
For current information on transceivers and cables supported by this device, refer
to the Fibre Channel Transceiver Support Matrix on www.brocade.com and to the
current Fabric OS Release Notes:
Core routing blades
QSFPs installed in core routing blades are used for connecting inter-switch links
(ICLs) between SAN512B-6 and SAN256B-6 switches or between SAN512B-6 or
SAN256B-6 and SAN384B-2 or SAN768B-2 switches. Interconnecting these devices
increases the number of usable ports for device connections.
Following are types of QSFPs installed in core routing blades:
v Separate MTP cable and transceiver. The transceiver is inserted into the blade
port and the cable plugs into a QSFP on the other end of the ICL.
1 - Pull tab
2 - QSFP cable
3 - QSFP transceiver
Note: If the fiber optic cables are not connected to the transceivers, make sure
the rubber sealing gaskets are plugged into the transceivers.
v 2 km LWL 16 Gbps QSFP transceiver with integrated MTP cable. The transceiver
is inserted into the blade port connector and integrated cable plugs into a QSFP
on the other end of the ICL, a patch panel, or a patch cable.
