Confirm the specification, for the exact model

Confirm the specification for the exact model, in writing, with the rate, the reach, the fiber type, and the connector, and compare it to the equipment's requirements, because a specification that matches on all four is hardware that will serve, and a specification that mismatches on any one is hardware that will not. Do not pay on title words alone, because a title names a model's headline features but does not evidence its full specification, and hardware paid for on title words alone may mismatch the equipment it must serve, however right its title appears, with a mismatch discovered only when the shipment arrives, when correction costs shipping, delay, and dispute.

Ask for the specification document, with the model's name, the rate, the reach, the fiber type, and the connector, and read it against the equipment's documentation, line by line, because a line that mismatches is a shipment that will fail, and a line that matches is a shipment that will serve. A specification confirmed in writing, before payment, is a specification that can be relied on, and a specification assumed, or inferred from a title, is a specification that cannot, because assumption is not evidence, and inference from a title is not a specification.

Confirm compatibility, for your equipment

Confirm compatibility for your exact equipment, in writing, naming its model, its software version, and its existing modules, because a general compatibility statement is a starting point, not a confirmation, and because a specific equipment needs a specific confirmation, for that equipment, before payment. The company profile states compatibility with Huawei, Cisco, HP, H3C, Juniper and MikroTik, with attribution, and that statement is the company profile's own statement, not a statement by any named equipment maker, and it does not imply authorisation, certification, or partnership with them, so a buyer who relies on it alone has relied on a general statement for a specific equipment, and a specific equipment needs a specific confirmation, in writing, before payment.

Ask for the compatibility confirmation as a written statement, naming the equipment and the module, so the confirmation is specific rather than general, and so a mismatch discovered after payment — a module rejected by the equipment's software, a module that fits but does not link — can be traced to a confirmation that was, or was not, given. A confirmation given in writing, before payment, is a confirmation that can be relied on, and a confirmation assumed from a general statement is a confirmation that cannot, because a general statement confirms no specific equipment.

Confirm the minimum order, and what it counts

Before payment, confirm the minimum order quantity for the exact model, and confirm what it counts: pieces, cartons, or orders, because a minimum stated in one unit is not the same as a minimum stated in another, and because a buyer who orders the minimum in the wrong unit will either order too few, and face a rejected order, or order too many, and face unwanted stock. Ask for the minimum in writing, with its unit, and compare it to the quantity you need, because a minimum that exceeds your need is a quantity you must either accept or negotiate, and a minimum that fits your need is a quantity you can order without waste.

Confirm the quantity as well: the exact quantity you will receive, in the exact unit, with the exact packaging, because a quantity confirmed in one unit and delivered in another is a quantity dispute, and because a buyer who pays for a quantity confirmed in writing, in the unit ordered, will receive what was paid for, while a buyer who pays for a quantity assumed, or inferred from a general claim, will receive what the supplier interprets, which may differ. Quantity confirmed in writing, before payment, is quantity that can be relied on.

Confirm the lead time, and what it counts from

Before payment, confirm the lead time for the exact model, and confirm what it counts from: order, payment, or production start, because a lead time counted from order is not the same as a lead time counted from payment, and a lead time that excludes shipping is not a delivery time, and because a buyer who plans on a lead time counted from the wrong start will plan for a delivery that arrives later than expected, with a project delayed, a customer disappointed, and a schedule disrupted. Ask for the lead time in writing, with its start point, its end point, and whether it includes shipping, because a lead time stated without its start and end is a lead time that cannot be planned on.

Ask for the delivery terms as well: who ships, who pays for shipping, who insures, and who bears the risk in transit, because a delivery term that is not written down is a delivery term that cannot be relied on, and because a buyer who pays for hardware whose delivery terms were assumed will face a delivery dispute, a shipping cost, or a transit loss that was not planned for. Delivery terms confirmed in writing, before payment, are delivery terms that can be relied on, and delivery terms assumed are delivery terms that cannot.

Confirm the warranty, with its meaning

Before payment, confirm the warranty term for the exact model, in writing, with its meaning: what it covers, what it excludes, how long it lasts, from when it runs, and how a claim is made, because a warranty term that is not written down, with its meaning, is not a term a buyer can rely on, and because a buyer who pays on an unwritten warranty has paid on a hope, which will disappoint when a claim is made, and when the supplier's interpretation differs from the buyer's expectation. Ask whether the warranty covers the hardware alone or the installation, whether it covers defects alone or failures in service, and whether it requires return, replacement, or repair, because each answer changes what the warranty is worth, and because a warranty whose meaning is unknown is a warranty whose value is unknown.

Ask for the warranty document, with the model's name, the term, and the claim process, and read it before paying, because a warranty document read before payment is a warranty that can be relied on, and a warranty document read after payment is a warranty that cannot be changed, however unfavourable its terms appear. No site-wide warranty is stated on this site, because no site-wide warranty is evidenced, and a warranty stated for one model cannot be assumed for another, so confirm the warranty for your exact model, in writing, before payment, and do not assume it from any other model's page.

Confirm the payment and shipping terms

Before payment, confirm the payment terms, in writing: what is paid, when it is paid, how it is paid, and what happens if the shipment does not serve, because payment terms that are not written down are payment terms that cannot be relied on, and because a buyer who pays on unwritten terms has paid on a hope, which will disappoint when the shipment fails, and when the supplier's interpretation differs from the buyer's expectation. Ask for the payment schedule, the payment method, the currency, and the refund or replacement process, because each answer changes what the payment is worth, and because a payment whose terms are unknown is a payment whose recourse is unknown.

Confirm the shipping terms as well, in writing: who ships, who pays, who insures, who bears transit risk, and what happens if the shipment is lost, damaged, or delayed, because shipping terms that are not written down are shipping terms that cannot be relied on, and because a buyer who pays for hardware whose shipping terms were assumed will face a shipping dispute, a cost, or a loss that was not planned for. Payment and shipping terms confirmed in writing, before payment, are terms that can be relied on, and terms assumed are terms that cannot.

Confirm the certificates, by name

Before payment, confirm the certificates that apply to your market, by name, with documents attached, because a certificate that is not named, with its document, is a certificate that cannot be verified, and because a buyer who pays on an unnamed certificate has paid on a claim, not on evidence, which will disappoint when the market's regulator asks for the certificate, and when the certificate cannot be produced. Ask for each certificate by name, with its document, and check that the document matches the model, the market, and the requirement, because a certificate for another model, another market, or another requirement does not satisfy your market, however genuine it appears.

Certificates are available upon request on this site, with no names, numbers, or issuers stated, because none are evidenced as current, and because an expired or undated certificate cannot be presented as current. A buyer who needs certificates for their market should ask for them by name, in the inquiry, with documents attached, and should check those documents before paying, because a certificate checked before payment is a certificate that can be relied on, and a certificate checked after payment is a certificate that cannot be changed, however unfavourable its terms appear.

Pay only on written confirmations

Pay only when every confirmation is written: the specification for the exact model, the compatibility for your exact equipment, the minimum order with its unit, the lead time with its start and end, the warranty with its meaning, the payment and shipping terms, and the certificates by name, with documents attached. Read every confirmation against the installation's facts, before paying, because a confirmation that mismatches is a shipment that will fail, and a confirmation that matches is a shipment that will serve, and because a mismatch found before payment can be corrected, while a mismatch found after payment must be returned, replaced, or disputed, at cost, delay, and effort.

A buyer who pays only on written confirmations has bought hardware that will serve, because its specification, its trade terms, and its certificates were checked against the installation's facts before the money moved, and a buyer who pays on assumptions, on titles, or on general claims has bought hardware that may or may not serve, with the uncertainty discovered only when the shipment arrives. Pay on writing, not on hope, because writing can be relied on, and hope cannot, and because the hour spent confirming before payment saves the shipment, the delay, and the dispute that follow a payment made without it.
