Netgear GS724T Smart Switch Teardown

03 December 2008
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Overview / Main Features

The Netgear ProSafe GS724T is a rack-mountable 24-port gigabit Ethernet smart switch with 2 swappable optical SFP slots [for both fiber and copper networks].

Per manufacturer-

The GS724T features, "24 10/100/1000 ports deliver non-blocking, full-speed packet forwarding with 48 Gbps bandwidth migrates your network to future-proof functionality. Two Dual Personality SFP GBIC fiber slots provide optional fiber connectivity for greater distance.

""Smart Switch capability enables key management features for the value price of an unmanaged switch. Included are performance monitoring, port configuration, VLAN for traffic control, port trunking for increased bandwidth, and Class of Service (CoS) for traffic prioritization."

Target Market

Small to midsize businesses or office environment with limited networking needs.

Released

Based on our understanding, first release in H1 2004.

Pricing and Availability
Pricing - The GS724T smart switch retails for $299 according to Netgear. Channel pricing appears to vary between $300 and $400 at time of writing (September 2008).

Availability

- This Netgear wired communications product is currently available globally through Netgear directly and various IT sales channels. This unit under analysis (GS724TNA) is specific to the North American market.

Volume Estimations

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 2M units.

As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed, volumes increment by an order of magnitude. Minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis.

What Is Not Included in our Cost Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software development cost, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

Manufacturing Notes

OEM/ODM/EMS Relationships / Manufacturing

According to Netgear's 10-K filings, Netgear has as their primary EMS providers: ASUSTek Computer, Inc. and its wholly owned subsidiaries, Cameo Communications Inc., Delta Networks Incorporated, Hon Hai Precision Industry Co., Ltd. (more commonly known as Foxconn Corporation), SerComm Corporation, and Unihan Corporation (which was spun out of ASUSTek Computer, Inc. in January 2008).

Country of Origin / Volume Assumptions

Based on markings, the unit was assembled in China. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc.) were also sourced in China.

Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as RJ-45 and SFP ports), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ""Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pin-count of the device. This calculation is affected by country or region of origin as well.

Design for Manufacturing / Device Complexity

The Netgear GS725T smart switch has a component count of 1505 (excluding box contents), of which, 74 are mechanical in nature.

Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design. The cost of manufacturing is also, to some extent, decreased in this case because of assumed labor rate applied for China.

Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.
