RUIJIE - RG-CS85-48SFP4XS-D - 48-Port 1G SFP Layer 3 Core or Aggregation Switch, 4 x 10G SFP+ Uplinks
Product Features
Layer 3 core or aggregation switch with 48 x 1GE SFP ports and four 1GE/10GE SFP+ ports, plus one expansion slot for the CM85-4XS2CQ module. Every port in use needs an SFP module or cable, and at least one RG-PA150IB-F power module must be bought separately.
RG-CS85-48SFP4XS-D — 48-Port 1G SFP Layer 3 Core or Aggregation Switch, 4 x 10G SFP+ Uplinks
The RG-CS85-48SFP4XS-D is a Layer 3 enterprise-class switch with 48 x 1GE SFP ports and four 1GE/10GE SFP+ ports for 10GE uplinks. Ruijie position it as an aggregation switch for large-sized networks or a core switch for small and medium-sized networks.
What the RG-CS85-48SFP4XS-D is for
Ruijie describe the RG-CS85 series as suited to aggregation on large-sized networks, or to the core of small and medium-sized ones. This model has 48 x 1GE SFP ports, so each link takes whichever SFP module or cable suits the run, and four 1GE/10GE SFP+ ports provide 10GE uplinks. The only RJ45 ports are for console and management.
Switching capacity is 656 Gbps and the packet forwarding rate is 488 Mpps. The specification lists 64,000 MAC addresses, 24,000 ARP entries, 24,000 IPv4 unicast routes and 14,000 IPv6 unicast routes, with up to four switches as VSU members. Check these table sizes against your design before ordering.
The single expansion slot takes the CM85-4XS2CQ module, which adds four 1GE/10GE SFP+ ports and two 40GE/100GE QSFP28 ports. Two power module slots give 1+1 power redundancy when both are filled, and power modules can be hot swapped. Three fan modules are pre-installed.

The table shows the hardware specification. Ruijie publish the full software feature list on the datasheet; ask us if you need a particular protocol or feature confirmed.
What you will need
At least one RG-PA150IB-F power module, which Ruijie's ordering information asks you to purchase with the switch; fit two for 1+1 power redundancy. With no RJ45 service ports, every port you use needs a module or cable: SFP modules for the 48 SFP ports and, for 10GE, SFP+ modules in the SFP+ ports (a 1G SFP module will not run at 10G). Tell us what sits at the other end of each link and we will check the modules. The CM85-4XS2CQ expansion module is only needed if you want the extra ports. More options are in our network switches and data networking ranges.
Buying from Zenith Security Co.
We are a supplier, not an installer. We will go through the RG-CS85-48SFP4XS-D with you before you buy — the SFP modules you need for each port, the power modules to fit and your uplink plan — and depending on your requirements and your area we can recommend a qualified trade installer. We have been operating since 2012 and you can visit our trade counter in Wolverhampton.
What ports does the RG-CS85-48SFP4XS-D have?
It has 48 x 1GE SFP ports and 4 x 1GE/10GE SFP+ ports, plus one expansion slot, one RJ45 console port, one RJ45 MGMT port and one USB 3.0 port. There are no RJ45 service ports, so each port in use needs a module or cable.
Is a power supply included with the RG-CS85-48SFP4XS-D?
The power module is not part of the base switch: Ruijie's ordering information says to purchase at least one RG-PA150IB-F module. The two power module slots give 1+1 power redundancy when both are filled, and the three fan modules are pre-installed.
Can the RG-CS85-48SFP4XS-D run its uplinks at 10G?
Yes, the four SFP+ ports are 1GE/10GE, so they run at 10G with 10G SFP+ modules. A 1G SFP module will not run at 10G.
What does the expansion slot on the RG-CS85-48SFP4XS-D add?
The slot takes the CM85-4XS2CQ module, which adds 4 x 1GE/10GE SFP+ ports and 2 x 40GE/100GE QSFP28 ports. The module is not needed to use the 48 SFP ports or the four fixed SFP+ ports.
How large are the tables on the RG-CS85-48SFP4XS-D?
The specification lists 64,000 MAC addresses, 24,000 ARP entries, 24,000 IPv4 unicast routes and 14,000 IPv6 unicast routes, with up to four VSU members. Check these against your design, and tell us if you want a second opinion.
How quickly can I get it?
Delivery is within 1–3 working days to England, Scotland and Wales. We do not ship to Northern Ireland.
Can I collect or see one before buying?
Yes. Our trade counter is at Unit 3, Park View Centre, 243 Dudley Road, Wolverhampton WV2 3JU. Call first so we can confirm the item is there for you.
