The CE5855-48T4S2Q-EI-B is a 1U, high-density 10G SFP+ Ethernet switch built for server access and spine-leaf fabrics inside modern data centres. Forty-eight line-rate 10GE SFP+ front-panel ports plus four 40GE QSFP+ uplink ports deliver a non-blocking design that keeps east-west traffic flat while leaving headroom for aggregation.
Every unit we ship is rack-tested before dispatch: ports are verified individually against optics, the uplink modules are looped back, and fan and power modules are run under load so that what you install matches the test sheet in the box. This listing is for buyers who need a repeatable, documented hardware source for 10G SFP+ switch rollouts, not a one-off marketplace transaction.
The front panel carries 48 x 10GE SFP+ cages wired for 10G Base-X optics and DAC cables, followed by four 40GE QSFP+ ports reserved for uplinks to a leaf-spine core or for high-bandwidth server groups. Access ports hold line rate in both directions, so a 10G SFP+ server link does not have to share oversubscribed backplane capacity with its neighbours. Rear-side serviceability is straightforward: dual AC power modules and a removable fan tray are hot swappable, and the airflow direction is front-to-back, matching standard data centre hot-aisle and cold-aisle layouts.

| Scenario | How the switch is used |
|---|---|
| Server access / ToR | Top-of-rack access for 10G NIC servers, dual-homed to two leaf switches. |
| Spine-leaf fabric | Leaf role with 40G QSFP+ uplinks to the spine, supporting MLAG and ECMP paths. |
| Storage networking | Low-latency iSCSI, NAS and backup traffic where tail latency affects job completion time. |
| Enterprise campus core | Collapsed core for mid-size sites needing 10G aggregation with 40G backhaul. |
| HPC and render farms | Dense 10G fan-out for compute nodes with predictable east-west bandwidth. |
Q: How many 10G SFP+ ports does the CE5855-48T4S2Q-EI-B provide, and can the 40G ports also be used for servers?
A: There are 48 x 10GE SFP+ access ports and 4 x 40GE QSFP+ ports. The QSFP+ ports ship configured as uplinks, and each can be broken out into four 10G links when you need extra server-facing capacity.
Q: Is this 10G SFP+ switch suitable for a spine-leaf data center fabric?
A: Yes. The 48-port density and four 40G uplinks are sized for the leaf role, and the platform supports MLAG and ECMP so each server has two independent paths to the spine.
Q: Why does sub-microsecond latency matter for a data center Ethernet switch?
A: In distributed storage and cluster workloads, queueing delay compounds across every hop. Keeping forwarding latency under one microsecond regardless of frame size removes the switch as a variable when you tune application performance.
Q: What power and cooling arrangement does the unit need?
A: Two hot-swappable AC supplies run in 1+1 redundancy on 100-240 V AC, and the removable fan tray pulls air front-to-back, so a single cold-aisle feed and standard cabinet depth are enough.
Q: What is included with each unit and how is it verified?
A: Each switch ships with its power modules, fan tray and rack ears, together with a port-by-port test record and the matching serial number. Units are covered by a 12-month hardware warranty, and our engineers can confirm optic compatibility with your existing 10G SFP+ and 40G QSFP+ inventory before shipment.
Tell us the quantity, the optics or DAC cables you plan to pair, and whether the deployment is new-build or refresh. We confirm power module type, airflow direction and firmware level against your rack requirements before dispatch, and we can supply mixed quantities with matching batches for multi-site rollouts. For teams standardising a 40G QSFP+ switch layer across several sites, we keep spare units and modules available for staged cutover windows.
