Hi Temp warnings will trigger at lower temperatures (~50C)if Commercial Temp vs Industrial Temp transceivers (~70C) are used. All Third Party transceivers are treated as Commercial Temp, regardless of capability. The 8360 32Y4C and 48Y6C models require configuration of "interface groups" only for ports 1-4 (as group #1) to enable the use of 10G transceivers / DACs in the SFP28 ports (Interface Groups default to 25G speed). Ports 1-4 on the 8360 32Y4C model do not support 1G transceivers.

The 8325 requires configuration of "interface groups" (groups of 12 ports) to enable use of 1G or 10G transceivers or DACs in the SFP28 ports (default is to use 25G transceivers / DACs). See theR0X44A/R0X44C when in default mode, auto-detects the inserted type of transceiver; it does NOT require any interface groups like the 8325. The JL687A module requires configuration of "interface groups" (groups of 4 ports) to enable the use of 1G or 10G transceivers / DACs in the SFP28 ports (default is to use 25G transceivers / DACs). JL687A 32p 25G module requires configuration of "interface groups" (groups of 4 ports) to enable use of 1G or 10G transceivers or DACs in the SFP28 ports (Interface Groups default to 25G speed). See the Installation Guide for details. The 8325 requires configuration of "interface groups" (groups of 12 ports) to enable the use of 1G or 10G transceivers / DACs in the SFP28 ports (default is to use 25G transceivers / DACs). This HP® J4858D compatible SFP transceiver provides 1000Base-SX throughput up to 550m over multi-mode fiber (MMF) using a wavelength of 850nm via an LC connector. It can operate at temperatures between 0 and 70C. Our transceiver is built to meet or exceed OEM specifications and is guaranteed to be 100% compatible with HP®. It has been programmed, uniquely serialized, and tested for data-traffic and application to ensure that it will initialize and perform identically. All of our transceivers comply with Multi-Source Agreement (MSA) standards to provide seamless network integration. Additional product features include Digital Optical Monitoring (DOM) support which allows access to real-time operating parameters. This transceiver is Trade Agreements Act (TAA) compliant. We stand behind the quality of our products and proudly offer a limited lifetime warranty. Technical Specification Compatible OEM

The 8325 requires configuration of "interface groups" (groups of 12 ports) to enable use of 1G or 10G transceivers or DACs in the SFP28 ports (Interface Groups default to 25G speed). See the Installation Guide for details. For sure at the very same maximum distance capable when using tested OM2 MMF cables (50/125 um 850 nm), so up to 550 meters.All in all: a 2930F on one side with a J4858D ina SFP+ slot, a 2930M on the other side with a J4858D ina SFP slot, approx 300 meters of OM3 fiber, will it work at 1G? For use in the SFP ports on the models listed, and in an installed J9312A 10GbE 2-port SFP⁠+/2-port CX4 yl Model JL687A 32p 25G module requires configuration of "interface groups" (groups of 4 ports) to enable use of 1G or 10G transceivers or DACs in the SFP28 ports (default is to use 25G transceivers / DACs). See the ER (J9153A/D) transceivers are limited to a maximum of two transceivers per J9309A or J9538A modules when used in a 5400zl or 8200zl chassis.
