The 7210 SAS-Sx 10/100GE 64SFP+ 4CFP4 and 7210 SAS-Sx 10/100GE 64SFP+ 4QSFP28 variants each provide 64 1GE/10GE SFP+ ports and 4 100GE CFP4 or QSFP28 ports, providing a platform for high-density 10GE Ethernet access and access aggregation with 100GE uplinks.
Both variants are 1.5RU platforms, with front access to all the 10GE and 100GE service interfaces. Both provide redundant hot-swappable power supplies (AC, -48V DC) and a non-removable set of fans on the rear of the chassis for cooling, with detection and notification of single fan failure. Both variants provide a Console port and out-of-band Ethernet management interface on the rear of the chassis.
Both variants support the use of a 1GE fiber-optic SFP in a 10GE SFP+ port. With this functionality, a single platform can be used to deliver both 1GE and 10GE services. This enables operators to continue to provide 1GE service or to build a 1GE access network and simultaneously migrate to deliver 10GE service and build a 10GE access network to address the growing bandwidth needs driven by cloud applications and migration to 4G/5G mobile networks. For a list of SFPs supported for 1GE operation, contact your Nokia representative.
Before using a 1GE SFP in an SFP+ port, the SFP+ port speed must be set to 1000 Mb/s with the config>port>ethernet>speed command; otherwise, an error message is generated indicating that the SFP is unsupported. For information about setting the port speed, see the "Ethernet Port Commands" section of the 7210 SAS-Mxp, R6, R12, S, Sx, T Interface Configuration Guide.
SFP+ ports that support SFPs do not support speeds of 10 Mb/s or 100 Mb/s.
On the 7210 SAS-Sx 10/100GE 64SFP+ 4CFP4 variant, ports on the front panel are named 1/1/1 to 1/1/64 for the 64 SFP+ ports, and 1/1/65 to 1/1/68 for the four 100GE CFP4 ports.
On the 7210 SAS-Sx 10/100GE 64SFP+ 4QSFP28 variant, ports on the front panel are named 1/1/1 to 1/1/64 for the 64 SFP+ ports, and 1/1/c1, 1/1/c2, 1/1/c3, and 1/1/c4 for the four100GE QSFP28 ports.
The platforms can be operated in two modes of operations: satellite mode and standalone mode:
In satellite mode, it provides port expansion function and the platform is managed by the 7x50 host. It does not need to be assigned an IP address. User needs to connect the right ports to the 7x50 and power on the node. The node automatically fetches the BOF, the image and the configuration required to operate in satellite mode.
In standalone mode, the platform provides IP/MPLS functionality and needs to be an IP address and managed independently.
