Quick Answer: Is the 45W0494 compatible with my switch?
Pro Disk Network validates every 45W0494 against the target switch's published compatibility matrix before shipment. If you let us know your switch model and firmware version, we will confirm fitment and code the module appropriately (Cisco-coded, Juniper-coded, HPE-coded, etc.) at no extra charge.
How fast does the 45W0494 ship?
45W0494 orders placed before 2 pm ET ship the same business day from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
The 45W0494 is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.
Server Uplink — 10G/25G server-to-leaf uplink — pair with matching DAC or AOC at the host NIC to avoid optic mismatch.
DCI (Data Center Interconnect) — Inter-DC routing or aggregation. LR4/LR8 transceivers for 10–80 km, ER4 for 40 km, ZR4 for coherent long-haul.
Campus Distribution — Catalyst-class campus distribution between IDF and MDF closets. PoE+ where wireless APs and IP phones share infrastructure.
Branch / Edge — Smaller form-factor switches and routers for branch sites. SD-WAN-compatible or static-VPN-attached as the architecture dictates.
New, Bulk, or Refurbished — Choosing Your Tier
Pro Disk Network offers the 45W0494 across three procurement tiers. Each tier is fully functional and warranted; the choice comes down to budget, warranty length, and whether the deployment is production-critical or capacity-expansion.

Pro Disk Network Buyer’s Guide: Networking Devices
Optic Coding, Vendor Lock-In, and Multi-Vendor Compatibility
For Cisco IOS, IOS-XE, and NX-OS switches, the 45W0494 works out-of-box if coded for Cisco; for Aruba ArubaOS-CX, code for HPE/Aruba; for Juniper Junos, code for Juniper. Pro Disk Network confirms the target vendor coding at order time and applies it before shipping. Misordered coding can be flashed in the field but the lead time is longer than ordering correctly the first time.
Bandwidth Sizing for Spine-Leaf, EVPN-VXLAN, and Hyperconverged Storage
Document optic types and bandwidth in your network drawings: SR-SR for intra-rack, LR-LR for inter-rack and DCI, ZR4 for long-haul coherent. Mismatched optic-distance ratings is the most common cause of intermittent link errors that look like cable problems but aren't.
