PTX10008-PREMIUM

PTX10008-PREMIUM is a fan assembly for Juniper PTX1000 routing equipment: JNP10008/PTX10008 Redundant 8-slot chassis – price includes 2 Routing Engines, 6 Power Supplies, 2 Fan trays, 2 Fan tray Controllers and 6 Switch Fabric Cards.

Fans are the one part of a router that is genuinely consumable. Everything else in the chassis can run for a decade; a fan has bearings, runs continuously from the day it is installed, and fails predictably after some years. The failure is also rarely sudden — bearings get noisy and airflow drops before anything stops — which means a fan tray is one of the few components where a planned replacement is realistic rather than aspirational.

What happens when cooling fails is worth knowing in advance. A router that loses airflow does not usually keep running and then stop. It raises a thermal alarm, and if the temperature keeps climbing it will throttle or shut itself down to protect the silicon. That is the correct behaviour and it is also an outage, so a fan failure in a chassis with no spare on site becomes an emergency rather than a maintenance task. Holding one fan assembly per chassis type on site is among the cheapest availability improvements available.

Two things to confirm. The chassis, because fan assemblies are specific to it and some platforms have front-to-back and back-to-front airflow variants that must match the room’s cooling design rather than just fit the slot. And whether the chassis supports replacing it while running, because on some platforms it is hot-swappable and on others it is not, and that decides whether this is a maintenance-window job.

What this platform is for. The PTX1000 is a packet transport router from Juniper’s PTX line, built for core and peering duty. Knowing the family’s intended role is usually more useful than the part number when you are working out whether something fits: a chassis built for one job will do another, but rarely well, and the cost of that mismatch tends to show up as throughput or feature limits rather than as an outright failure.

Three questions worth answering before any router purchase, whatever the model. What the throughput requirement actually is with your feature set enabled, rather than the datasheet figure measured without it. Whether the features you need are licensed as well as present, since on most platforms security and performance are separate entitlements. And how many slots or ports you will need in three years, because adding capacity is cheap and replacing a chassis is not.

Worth knowing if you have not been following it: Juniper is now part of HPE. Hewlett Packard Enterprise completed its acquisition of Juniper Networks on 2 July 2025, and Juniper’s former chief executive now leads the combined HPE Networking business. HPE continues to list the Juniper lines, MX and PTX included, in its own portfolio.

For buying purposes that is mostly good news and it is directly relevant here, because we supply HPE as well. What the closing announcement did not do is make specific commitments about how long individual Juniper product lines will be sold or supported, so we are not going to imply any. If the lifecycle of a particular model matters to your decision, ask us and we will confirm it against HPE and Juniper’s current notices rather than guess from the acquisition.

Tell us the chassis and whether this is a spare or a replacement for something already failing, and we will confirm the right assembly and the airflow direction.

Green Code Technologies is a supplier of Juniper, and we supply Cisco and Huawei networking alongside HPE, Dell, Samsung, Netgear, Ubiquiti and Asus. We would rather tell you a part is no longer supported, or that we need to check it, than take an order for something that will not do what you need.
