Questions & Answers
What is the PTX 120A DC Redundant Power Supply Module (SKU PSM-PTX-DC-120-R)?
The PSM-PTX-DC-120-R is a hot-swappable, 120 A DC redundant power supply module designed to ensure uninterrupted power for PTX series chassis.
What are the key technical specifications of the PSM-PTX-DC-120-R?
It delivers 120 A output at 48 VDC, supports 36–75 VDC input, features active current sharing, LED status LEDs, and measures 2 RU in a PTX chassis.
How does the redundant feature enhance system reliability?
By operating in N+1 or 1+1 redundancy mode, the module automatically transfers the load to a backup unit upon primary failure, preventing downtime.
Is the PTX-120-R hot-swappable?
Yes. The PSM-PTX-DC-120-R can be inserted or removed without powering down the chassis, enabling continuous operation during maintenance.
What input voltage range does the PSM-PTX-DC-120-R support?
It supports a broad input range of 36 VDC to 75 VDC, accommodating typical Telco and data-center DC bus voltages.
Which PTX chassis models are compatible with this module?
The PSM-PTX-DC-120-R is compatible with all PTX 5000, 7000, and 9000 series chassis equipped with DC power sled bays.
How do I install the PSM-PTX-DC-120-R module?
Slide the module into an available power bay until the latches click, then connect the positive and negative DC bus leads per chassis labeling.
How can I monitor the power status remotely?
Use the chassis management card or SNMP interface to view real-time DC input voltage, current load, redundancy status, and fault alarms.
What safety and compliance certifications does it have?
It is UL 60950-1, CE, CB-Scheme, and RoHS certified, meeting global safety and environmental standards.
What is the efficiency rating of this power module?
The PSM-PTX-DC-120-R achieves up to 94% efficiency at typical load levels, reducing heat dissipation and operating costs.
What is the mean time between failures (MTBF)?
Its MTBF exceeds 300,000 hours at 25 °C ambient temperature, reflecting high reliability in continuous-operation environments.
What are the operating temperature and humidity ranges?
The module operates from –10 °C to 60 °C at up to 95% non-condensing relative humidity.
Does the PSM-PTX-DC-120-R come with a warranty?
Yes. It includes a standard 3-year return-to-factory warranty covering defects in materials and workmanship.
How do I troubleshoot common power module issues?
Check LED fault indicators, verify DC input voltage, inspect connector seating, and consult the chassis event log for alarm codes.
What is the expected service life of the module?
Under normal operating conditions, you can expect a service life of 5 to 7 years before end-of-life deprecation.
Where can I purchase replacement PSM-PTX-DC-120-R modules?
