The 7210 SAS-Sx 1/10GE is an IP/MPLS Ethernet device for business service applications and Ethernet mobile backhaul applications to be used as an access device or as an access aggregation device. It can also be operated in satellite mode, where it provides port expansion, allowing users to break out the 10GE ports on the 7x50 to 1GE ports.
7210 SAS-Sx 1/10GE is available in six variants:
7210 SAS-Sx 1/10GE 46F 2C 4SFP+
7210 SAS-Sx 1/10GE 22F 2C 4SFP+
7210 SAS-Sx 1/10GE 48T 4SFP+
7210 SAS-Sx 1/10GE 24T 4SFP+
7210 SAS-Sx 1/10GE 48Tp 4SFP+ PoE
7210 SAS-Sx 1/10GE 24Tp 4SFP+ PoE
All variants are 1RU platforms, designed to be NEBS compliant, supporting line-rate switching on all the ports, with the option for a redundant hot-swappable power supply. They also provide a console port and out-of-band Ethernet management interface on the rear of the chassis:
The 7210 SAS-Sx 1/10GE 46F 2C 4SFP+ and 7210 SAS-Sx 1/10GE 22F 2C 4SFP+ allow for 48 SFP ports and 24 SFP ports respectively, along with an option to use copper interfaces on two ports.
The 7210 SAS-Sx 1/10GE 48T 4SFP+ and 7210 SAS-Sx 1/10GE 24T 4SFP+ allow for 48 10/100/1000Mbps copper ports and 24 10/100/1000Mbps copper ports respectively.
The 7210 SAS-Sx 1/10GE 48Tp 4SFP+ PoE and 7210 SAS-Sx 1/10GE 24Tp 4SFP+ POE allow for 48 10/100/1000Mbps copper ports and 24 10/100/1000Mbps copper ports respectively, along with option to use PoE/PoE+, with a maximum of 720W of power being available to PoE devices across all the ports.
In addition, all variants support 4 x 10GE SFP+ ports that can be used as uplinks.
The following variants support the use of a 1GE fiber-optic SFP in a 10GE SFP+ port:
7210 SAS-Sx 1/10GE 48T 4SFP+
7210 SAS-Sx 1/10GE 24T 4SFP+
7210 SAS-Sx 1/10GE 48Tp 4SFP+ PoE
7210 SAS-Sx 1/10GE 24Tp 4SFP+ PoE
With this functionality, operators can use either 1GE or 10GE fiber uplinks. This enhancement provides the flexibility of using SFP+ ports as 1GE uplinks with the capability to move to 10GE uplinks as bandwidth demands grow. This functionality is supported for standalone mode only.
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.
The 7210 SAS-Sx 1/10GE can be operated in two modes – Standalone mode and Satellite mode:
In satellite mode, the platform is managed by the 7x50 host. It does not need to be assigned an IP address. The 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 assigned an IP address and managed independently.
