The HPE 849442-001 is the 25Gb SFP28 short-reach (SR) spare transceiver for HPE server networking, the part number engineers reach for when an existing 25GbE optic fails or when adapter ports need populating outside a formal configuration order. It is the spares-channel counterpart to the 845398-B21 option kit, providing the same qualified 25Gb short-reach optical connectivity for HPE SFP28 server adapters. Euroland IT Store stocks the 849442-001 new and refurbished, tested and ready for fast UK dispatch.
In service, this optic links SFP28 NIC ports to 25GbE top-of-rack switching over LC multimode fibre, carrying the virtualisation, container and storage traffic that defines the modern server edge. Because it is hot-pluggable, a failed unit can be swapped on a production host without a reboot, provided a spare is on hand, which is precisely why the 849442-001 features on so many data centre spares lists. A single optic failure on a bonded pair degrades redundancy immediately, so quick access to the exact replacement part protects both performance and resilience.
The buyers we supply are typically IT departments replacing failed optics under change control, MSPs maintaining customer estates to fixed SLAs, and resellers fulfilling spares contracts. All three need the same things: the exact HPE part number for supportability, honest tested stock, and pricing that makes holding spares economical.
That is Euroland IT Store’s role as a trusted UK supplier of enterprise spares and HPE parts. Every refurbished 849442-001 transceiver is tested before shipping, savings against list price are substantial, and new units are available where procurement policy demands. We can also cross-reference against the 845398-B21 option or your adapter part numbers to guarantee the right fit. Request a quote online or contact the team for stock levels and volume rates.
Keeping 849442-001 spares available turns the most common 25GbE failure mode, a dead optic, into a five-minute fix that restores full link speed and NIC redundancy without touching workloads. For teams running bonded 25Gb pairs on virtualisation hosts, that speed of recovery is the difference between a routine maintenance note and an at-risk change window. This spare installs into adapters such as the HPE P08443-B21 10/25Gb SFP28 Network Adapter, and buyers working from configuration records often cross-reference it with the HPE 845398-B21 25Gb SFP28 SR Transceiver option kit.
Using the exact HPE spare also protects supportability: ports negotiate cleanly at 25Gb, adapters remain within qualified configurations and support cases proceed without third-party optic disclaimers. Consistency across an estate simplifies both troubleshooting and asset records.
Commercially, Euroland IT Store makes resilience cheap. Tested refurbished 849442-001 units cost a fraction of list, so stocking spares per site, or even per rack row, is a minor line item rather than a budget request. Upstream, the HPE JL275A Aruba 100G QSFP28 Transceiver aggregates these 25Gb server connections at the core, and our full networking transceivers category covers every speed in between. New stock is available where required, UK inventory keeps delivery fast, and volume pricing supports MSPs and resellers maintaining multiple estates. Reliable links, quick recovery, sensible cost.
