PRODUCT DESCRIPTION
H3C S6520X-16ST-SI 10GE Layer 3 Switch (LS-6520X-16ST-SI-GL) - 3 Years Local Warranty
Sixteen 10G SFP+ Ports
The H3C S6520X-16ST-SI is a Layer 3 10GE switch with 16 x 1G/10G SFP+ ports, two of which are combo ports with 1G/10GBase-T RJ45, built for the SMB market.
Wire-Speed Performance
H3C rates the S6520X-16ST-SI at 320 Gbps port switching capacity and 240 Mpps forwarding, with a dual-core 1.6 GHz CPU, 1 GB flash and 2 GB SDRAM.
Dual Pluggable Power
Two power module slots give 1+1 redundancy with PSR75-12A modules. The switch ships without power supplies, so order at least one PSR75-12A-GL with it.
Full Layer 3 Routing and IRF2
Static, RIP, OSPF, BGP and IS-IS routing with VRRP, IRF2 stacking of up to 9 switches, M-LAG, VXLAN/EVPN and the free embedded SmartMC web manager.

Frequently Asked Questions — H3C S6520X-16ST-SI
Does the S6520X-16ST-SI include a power supply?
No. Per the H3C installation guide the switch ships with power slot 1 empty and a filler panel in slot 2. Order at least one PSR75-12A-GL (75 W AC, part 0231A7G9); fit two for 1+1 redundancy.
Which power supply does it use?
H3C lists the PSR75-12A (ordered as PSR75-12A-GL) as the removable 75 W AC power supply for the S6520X-16ST-SI.
Can I use copper on it?
Yes. Two of the 16 SFP+ ports are combo ports with 1G/10GBase-T RJ45 alternatives, per H3C.
Can I stack it?
Yes. IRF2 stacks up to 9 members using standard 10GE ports, per H3C.
What warranty do I get?
3 years local warranty in Singapore, supplied by SourceIT with a GST invoice.
