Key Benefits
What Owning JL355A Changes
Node Configuration Fixed to One Generation
1 x ARM: 1016 MHz quoted with the rails caddies and controller that belong to the same chassis generation, so the node racks on the day it lands.
Table Sizes Checked Against the Design
A MAC Address Table Size of 16384 entries on this model, the kind of ceiling that only becomes visible once a flat segment has grown.
A Complete Bill of Materials
Modules optics rails and power options are reviewed against JL355A before the quotation is issued, so the install crew is not blocked by a line nobody costed.
Support Registered Under the End User Name
A vendor support contract for JL355A is written under the end customer name, so the entitlement sits with the organisation that owns the outage.
Serials Issued Before It Ships
The serial list for your JL355A consignment is released before despatch, so it can be checked on the manufacturer portal while the goods are still with us.
Problems It Solves
Pain Points JL355A Removes
- AOS-Switch and ArubaOS-CX estates that have drifted into two toolchains
- End of sale announcements that leave a proven design with no supply route for JL355A
- A closet-by-closet rollout that needs the same SKU available years after the first order
- PoE budget that stopped covering the access points cameras and phones added since
- Uplink modules and stacking cables quoted separately and discovered missing on site
Who It Is For
Who Benefits Most From JL355A
Campus Network Teams
Running one access standard across buildings of very different ages
Education IT
Delivering inside vacation windows against a budget year that rarely aligns with the install date
System Integrators
Bidding work that needs firm pricing and a written lead time before the end client is quoted
Managed Service Providers
Standardising hardware across many customer sites and needing the same SKU available again

Use Guide
Deployment Guide for JL355A
Confirm the Full Part Number
Check JL355A character for character including any suffix. On this class of hardware a single trailing character commonly changes the software tier, the power option, or whether a bundle is included.
Check Site Prerequisites
Confirm rack space, power feed, cabling and any uplink or accessory dependency before the order rather than on the day of installation.
Record It on Arrival
Photograph the sealed carton, reconcile the serial against the list supplied before shipment, then open and confirm the unit matches the label.
Bench Power Before Racking
Power the unit, capture the software version and the port or drive inventory, and record it while the unit is still accessible.
Register Support Entitlement
Register the support contract under the end user name so the entitlement sits with the organisation that owns the outage.

Where It Goes
Industries That Deploy It
Data Center
Top of rack switching, compute and storage delivered in the phased increments a cabinet build actually consumes.
Enterprise Campus
Access, distribution and wireless supplied to one standard so every closet in every building behaves the same way.
Service Provider
Repeatable CPE and aggregation hardware supplied at the volume and consistency a managed service contract depends on.
Solutions
Programmes It Is Supplied Under
Global Logistics and Drop Shipping
Hong Kong is a practical despatch point for most of the world. Consignments go to the site, not to a central store and then out again.
Procurement for System Integrators
An integrator carries the risk between quoting a client and receiving the hardware. Firm pricing and a written lead time per line is what makes that risk manageable.
Network Refresh Programme
Most refresh projects fail on supply rather than on design. A phased programme only works if every phase arrives complete on the date the change window was booked.
Reference
Project Cases and Guides
Regional Bank Branch Refresh Across 140 Sites
The branch edge had reached end of software support and the estate had drifted into four different router models bought across eight years
University Campus Wi-Fi Density Upgrade
Lecture theatres and the library could not carry the client counts actually present, while the work could only happen during vacations
Access Switch Selection for Campus
Five decisions set the part number. Getting them in the right order prevents most of the changes that happen late in a project.
Access Point Mounting and Installation
Wireless installs are rarely delayed by the access point. They are delayed by the mount, the power class or the cable that feeds it.
Network Refresh Planning Checklist
Refresh programmes fail on supply far more often than on design. This is the sequence that keeps a phased rollout on its dates.
FAQ
JL355A Frequently Asked Questions
Is JL355A New or Refurbished
Standard supply is new factory sealed in the original vendor carton. If a quotation offers another condition that is stated explicitly in writing before you commit.
Can I Get the Serial Numbers for JL355A Before Payment Clears
Yes. Serials are issued before shipment so you can check them on the manufacturer portal while the goods are still with us.
What Is the Lead Time for JL355A
Availability is confirmed in writing per line at quotation rather than as a project average, because one late line is what moves an installation date.
What Warranty Does JL355A Carry
12 months replacement as standard. A vendor support contract is available separately and is registered under the end user name.
Are Uplink Modules and Optics Included With JL355A
They are quoted as separate lines and reviewed against the chassis before the quotation is issued, so they reach site in the same consignment as the unit they belong to.
What Table Sizes Does JL355A Carry
The published MAC Address Table Size is 16384 entries. Table ceilings usually only become visible once a flat segment has grown, so they are worth checking against the design rather than against today's estate.
Can You Ship JL355A to My Country
Yes. Consignments go worldwide by courier or freight from Hong Kong, with the routing chosen against the destination clearance regime and your deadline.
Can You Drop Ship JL355A to My Customer
Yes. Consignments can be released directly to an end customer address under your own documentation.
