Shipping Information

The shipping process is fully robotic and orders are pulled and shipped quickly in 7 different warehouses across the US and then dropped in sealed USPS, UPS and FedEx containers for pick-up on the next business day. Once pulled, orders cannot be stopped, however you can return orders for refund unopened if you have changed your mind. Tracking normally is sent / updated within 48 hours of pick-up. Delivery is normally 7 business days or less. It may take longer in rural areas. Weekends and Holidays do not count as business days and have no pickup, movement or delivery.

Covid 19 Update — We have seen some slowdowns and backlogs in package sorting and scanning by UPS, Fedex and USPS caused by worker shortages and closed facilities due to the Covid 19 Pandemic. Some UPS and USPS hubs are no longer scanning all packages, as a result some tracking will show nothing until delivery.

Chelsio's SM40G-SR 40Gb/s 100m Multimode QSFP+ optical transceivers are designed and certified for use with Chelsio's 40-Gigabit Ethernet Unified Wire Adapters. The Chelsio SM40G-SR Transceiver is compatible with Chelsio's T5-based Unified Wire Adapters.

The T5 adapters support PCI Express 3.0 host bus interface, and are optimized for storage, cloud computing, HPC, virtualization and other data center applications. The fifth-generation T5 ASIC technology from Chelsio provides the highest performance while dramatically lowering host-system CPU and memory overhead with on-board hardware that offloads TCP/IP, iSCSI, FCoE and iWARP RDMA processing. As a result, the system benefits from higher bandwidth, lower latency and reduced power consumption.
