Juniper 10G LR SFP+ Transceivers May Fail To Enter Service On SSR-1300 And SSR-1400 X722 Ports
Juniper 10G LR SFP+ transceivers, Juniper part number 740-021309, may fail to enter active service when installed in Intel X722 Network Interface Controller (NIC) ports on SSR-1300 and SSR-1400 routers.
Issue ID: I95-65908
Last Updated: 2026-09-25
Problem
The Intel X722 Network Interface Controller (NIC) is used for ports xe0/0 through xe0/3 on SSR-1300 and SSR-1400 routers. The X722 NIC firmware scans the EEPROM for each installed optical device and checks the device against an approved optics list built into the firmware. Optical devices that are not present in the approved optics list are not allowed into service on this NIC.
Juniper partners with several optical transceiver vendors to deliver Juniper-branded optics. For the Juniper 10G LR SFP+ transceiver portfolio, Juniper part number 740-021309, the EEPROM encoding for one specific vendor is not recognized by the X722 firmware. As a result, the transceiver may not enter active service when installed in an affected X722 port.1
Affected Products
| Product | Affected Ports |
|---|---|
| SSR-1300 | xe0/0 through xe0/3 |
| SSR-1400 | xe0/0 through xe0/3 |
Affected Transceiver
| Field | Value |
|---|---|
| Optic type | 10G LR SFP+ |
| Juniper part number | 740-021309 |
| Affected vendor encoding | JUNIPER-1W1 |
| Vendor OUI | 20:1b:c9 |

Symptom
When this issue occurs, the affected interface remains unavailable for forwarding. The port shows an Admin Status of down and an Operational Status of unknown.

Cause
The X722 NIC firmware does not recognize the EEPROM encoding used by one vendor variant of the Juniper 10G LR SFP+ transceiver, part number 740-021309. Because the optical device is not recognized as approved by the X722 firmware, the NIC does not allow the transceiver to enter service.
Identify The Affected Transceiver
SFP EEPROM data is accessible via PCLI in select SSR software versions using the show device-interface node <node> name <port> optics-statistics command. If this is not available in your version of SSR software, use the Linux ethtool command.
In order to use the Linux ethtool command on X722 ports, you must complete the firmware upgrade referenced earlier.
Affected Transceiver In X722 Port After NIC Firmware Upgrade
ethtool -m xe-0-1
Cannot get module EEPROM information: Input/output error
Affected Transceiver In A Non-X722 Port
When the same affected transceiver is installed in a non-X722 port where EEPROM data can be read, the EEPROM output includes the following vendor information:
ethtool -m xe-2-1
Vendor name : JUNIPER-1W1
Vendor OUI : 20:1b:c9
Vendor PN : 1W1T8A
If the ethtool output aligns with either of the examples above, the transceiver is not compatible with the X722 NIC, and should be replaced with a compatible, approved Juniper transceiver.
The output below is seen when the X722 NIC firmware upgrade is needed.1 Please upgrade the NIC firmware in order to capture the correct output, or move the transceiver to a non-X722 port to display the SFP information.
ethtool -m xe-0-1
i40e 0000:6a:00.1 xe-0-1: Module EEPROM memory read not supported. Please update the NVM image.
Workaround
No software workaround is available.
Resolution
Contact HPE technical support and initiate a return material authorization (RMA) request for the affected SFP only. HPE will replace the affected SFP.
When opening the support case, include the following information:
- SSR platform: SSR-1300 or SSR-1400
- Affected port: for example,
xe0/0,xe0/1,xe0/2, orxe0/3 - SSR software version
- Transceiver part number:
740-021309 - Interface status output showing:
Admin Status: downOperational Status: unknown
