Question 1

What are Juniper Router PTX modules & cards?

Accepted Answer

Juniper Router PTX modules & cards are high-performance line cards and interface modules designed for scalable packet transport, providing flexible port densities and advanced traffic management in core and edge networks.

Question 2

Which PTX modules support 100GbE and 400GbE interfaces?

Accepted Answer

PTX5000 series supports 100GbE via MPC7E line cards, while PTX10000 series offers both 100GbE and 400GbE using MPC10/MPC11 cards with QSFP28 and QSFP112 transceivers.

Question 3

How do I choose the right PTX module for my network?

Accepted Answer

Select a PTX module based on required interface type, port density, switching capacity and power budget, then verify compatibility with your PTX chassis and Junos OS release.

Question 4

What is the throughput capacity of a PTX1000 line card?

Accepted Answer

A PTX1000 line card delivers up to 4 Tbps of switching capacity with support for multiple 100GbE or 400GbE ports, ensuring sustained high-speed transport.

Question 5

Are Juniper PTX modules hot-swappable?

Accepted Answer

Yes, PTX modules and cards are hot-swappable, enabling in-service upgrades and replacements without network downtime when supported by the chassis.

Question 6

How do I install a PTX service module?

Accepted Answer

Power down the designated slot, insert the PTX service module until it locks, reconnect power and verify module status via the show chassis hardware command in Junos OS.

Question 7

What power and cooling requirements apply to PTX modules & cards?

Accepted Answer

PTX modules require redundant –48V DC power or AC power supplies and front-to-back cooling airflow; verify chassis power rating and airflow specifications in the PTX hardware guide.

Question 8

Can I mix different PTX cards in the same chassis?

Accepted Answer

Yes, Juniper PTX chassis support mixed line cards as long as the combined power, cooling and fabric capacity remain within chassis limits outlined in the hardware documentation.

Question 9

Do PTX modules require specific Junos OS versions?

Accepted Answer

Each PTX module has a minimum Junos OS version requirement; always consult the Junos release notes to ensure module compatibility and feature support.

Question 10

How do I upgrade firmware on PTX modules?

Accepted Answer

Use the request system firmware add CLI to upload firmware to onboard storage, then issue request system reboot or request system software add to apply the update in service.

Question 11

What is the warranty period for Juniper PTX line cards?

Accepted Answer

Juniper provides a limited lifetime warranty for PTX modules when purchased with a valid Juniper Care contract, covering defects and hardware failures.

Question 12

Does Juniper offer technical support for PTX modules & cards?

Accepted Answer

Yes, Juniper Care and Premium Support contracts include expert technical assistance, hardware replacement and software updates for all PTX modules & cards.

Question 13

What are the differences between PTX3000 and PTX10000 modules?

Accepted Answer

PTX3000 offers up to 4 Tbps capacity in a compact form, while PTX10000 scales up to 56 Tbps with higher slot density and advanced packet forwarding capabilities.

Question 14

How can I monitor performance on PTX service cards?

Accepted Answer

Use Junos OS operational commands like show interfaces and show services performance to view real-time throughput, packet counts and latency statistics.

Question 15

Which transceivers are compatible with PTX modules?

Accepted Answer

PTX modules support Juniper-branded SFP+, QSFP+, QSFP28 and QSFP112 transceivers; always verify support in the hardware compatibility matrix before deployment.

Question 16

How do I troubleshoot a link issue on a PTX line card?

Accepted Answer

Check interface status with show interfaces terse, validate transceiver diagnostics via show interfaces diagnostics optics and review chassis alarms for power or cooling alerts.
