Description

The FlexNetwork 3600 v2 SI is a 1U managed Layer 3 Fast Ethernet edge switch from the HPE 3600 v2 SI range, built for enterprise and SMB networks that need robust edge switching, including converged networks. This 48-port, non-PoE model suits access layers where end devices are powered separately.

The switch provides 48 autosensing 10/100 RJ-45 ports, two dual-personality 10/100/1000 SFP ports and two 1000 Mbps SFP ports for uplinks. It delivers 17.6 Gbps of routing and switching capacity, up to 13.1 Mpps throughput with 64-byte packets and a 55 Gbps switch fabric. Memory is 256 MB SDRAM and 128 MB flash, with a 4 MB packet buffer. It draws a maximum of 41 W from its internal 100-240 VAC supply. Standard Image software provides static and RIP Layer 3 routing, and up to nine units can be stacked as one virtual fabric using IRF.

Supported SFP options include the HPE X120 and X125 1G modules JD061A, JD062A, JD063B, JD089B, JD098B, JD099B, JD118B and JD119B. The switch can be managed through the CLI, web interface, SNMP or HPE Intelligent Management Center (IMC).

FAQs

Q: Does this switch support PoE?
A: No. The JG305B is a non-PoE model. For a 48-port PoE+ version, look at the JG307C.

Q: Does it need a separate software licence?
A: No separate licence is required. The Standard Image (SI) software ships with the switch and provides static and RIP Layer 3 routing.

Q: Which SFP modules can I use in the uplink slots?
A: Supported HPE 1G SFP modules include JD061A, JD062A, JD063B, JD089B, JD098B, JD099B, JD118B and JD119B, covering SX, LX, long-haul, BiDi and RJ45 options.

Q: How does it differ from the JG304B and JG307C?
A: The JG305B has 48 non-PoE 10/100 ports. The JG304B has 24 non-PoE ports, while the JG306C and JG307C add PoE+ with 24 and 48 ports respectively.

Q: Can multiple units be stacked?
A: Yes. IRF stacking lets up to nine switches be managed as a single virtual fabric with one IP address.
