About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

Many people have resorted to networking as the best alternative to services. There is a growing demand for a reliable networking system that will make it possible to collaborate and share data over the network. As a result, power outages and downtimes are undesirable. If you want to make your system more reliable and immune to disruptions, then buy a power module.

Obtain Increased Power and Cooling with Power Modules

Most of the power modules, such as the 15454-M6-AC Cisco AC power supply, have a total of 8 slots: two for redundancy and 6 for line card slots. These slots provide improved power cooling capabilities to keep the system running under optimal conditions. The form factor is also a universal one that can be mounted on any server rack in any part of the world.

Easy Installation on the Racks

Power modules can be designed to easily mount onto the racks. Some can easily sit on 19-inch, 21-inch, or 23-inch racks, but that depends on the power control module model in question. Each rack size has its design for airflow, which affects how you mount these power modules onto them. Installing power modules is never a difficult task, but you might need technical assistance if you are less experienced.

Warning Alarm for Failed Components

A power module always comes with fans for cooling. The number of fans that you will find in any module also depends on the model. Some power modules have one, two, three, or more fans. The fans are carefully monitored, and a failure of any of them triggers an alarm. For a multi-fan power module, the speeds of other fans are increased to compensate for the faulty one.

Power Modules Designed for Specific Applications

You cannot use just any power module for your system. You need to find the right one for the intended purpose. For example, if your system is HPE ProLiant D-series, then the appropriate power module to buy is 738024-B21 HP power supply. That should apply to any other model because they have different output power ratings.
