IBM compatible 22R4902 Description
EdgeOptic's 10G-SFP-300 compatible is an IBM-coded 10GBASE-SR SFP+ transceiver that replaces the 22R4902 FRU. The 22R prefix belongs to IBM's storage and SAN component numbering, and this part number appears in IBM System Storage DS3000, DS4000, and DS5000 series arrays as well as BladeCenter blade servers. EdgeOptic programs the EEPROM with IBM-recognized vendor data, so the module registers as a supported optic without requiring manual overrides or firmware workarounds.
IBM's DS-series storage arrays rely on 10 GbE and Fibre Channel SFP+ optics for inter-shelf links, host-bus adapter uplinks, and SAN fabric connections. Each DS controller pair typically presents two to four SFP+ host ports per controller for redundant path connectivity to the SAN fabric. The 22R4902 was originally specified for these environments during the DS3000/DS5000 era, covering both 10GBASE-SR Ethernet at 10.3125 Gbps and 8G Fibre Channel per FC-PI-4. BladeCenter deployments used the same FRU for blade-to-switch module connections inside the chassis midplane. Organizations still running DS-series arrays or BladeCenter infrastructure can source the 22R4902 as a direct replacement without platform re-qualification. The DS3500 and DS5020 arrays use dual-controller active-active configurations where each controller has SFP+ host ports for iSCSI or FC front-end connectivity. The 22R4902 slots into these host interface cards alongside the existing IBM-validated optics. IBM BladeCenter H chassis also reference this FRU for the Cisco 3012, Nortel L2/3 GbE, and BNT 10G Ethernet switch modules installed in the interconnect bays.
The optical interface uses an 850 nm VCSEL transmitter and PIN photodiode receiver over duplex LC multimode fiber. Link budget is 6.1 dB, supporting 300 m on OM3 and 400 m on OM4 cabling. DDM (Digital Diagnostic Monitoring) provides real-time readings for TX power, RX power, temperature, bias current, and supply voltage. The module conforms to IEEE 802.3ae 10GBASE-SR and SFF-8472 for diagnostic data. Operating temperature range is 0 to 70 degrees C (commercial grade).

Frequently Asked Questions
Which IBM platforms use the 22R4902 SFP+ module?
The 22R4902 is an IBM FRU used in System Storage DS3000, DS4000, and DS5000 series arrays, as well as BladeCenter blade server chassis. It provides 10GBASE-SR Ethernet and multi-rate Fibre Channel connectivity for inter-shelf links, HBA uplinks, and SAN fabric connections in these environments.
Does the EdgeOptic 22R4902 compatible require firmware changes on IBM storage arrays?
No. EdgeOptic programs the EEPROM with IBM-recognized vendor data, so DS-series storage controllers and BladeCenter switch modules accept the transceiver as a supported optic. No firmware changes or manual overrides are needed.
Can the 22R4902 handle both Ethernet and Fibre Channel traffic?
Yes. The module supports 10GBASE-SR Ethernet at 10.3125 Gbps and multi-rate Fibre Channel at 8G FC (8.5 Gbps) with backward compatibility to lower FC rates. This multi-protocol capability matches the original IBM 22R4902 specification for mixed SAN/LAN environments.
