| Q1. |
Are there any new products in the HP Modular PDU product line? |
| A1. |
Yes. There are new three phase Modular PDUs now available specifically for high current applications such as BladeSystems. These new units are the core only and do not include extension bars.
|
|
| Q2. |
What new features exist in the HP Modular PDUs? |
| A2. |
There is a new 17.3 kVA Core Only model for North America and Japan and a new 22.1 kVA Core oNly model for International use.
|
|
| Q3. |
What's the significance of the "Modular" architecture? |
| A3. |
The modular architecture brings you the added benefits and flexibility. You have the option to mount both the Control Unit and the Extension Bars in several different locations in the rack, helping you to configure the PDU in a way that best suits your needs. This also allows you to easily access the outlet receptacles, and to also reduce cable clutter by using shorter cables.
|
|
| Q4. |
What are the basic components of the HP Modular PDU? |
| A4. |
There are two basic building blocks - the Control Unit and the Extension Bar(s). The Control Unit distributes single input power into 4 single-phase branch outputs. The Extension Bars connect to the Control Unit to extend along the length of the rack to offer multiple outlets/receptacles.
|
|
| Q5. |
What is the purpose of the Control Unit? |
| A5. |
The Control Unit receives single-phase input power and distributes it into 2- 4 single-phase branch circuits. The Control Unit houses the main power switch, circuit breakers, load groups, and power-on light. Control Unit Features include:
- Overcurrent and short current protection for each branch circuit (four 15A UL-489 Listed circuit breakers)
- Easy identification of overloaded circuits (full trip circuit breakers move to OFF position) minimizing downtime due to overload conditions
- Manual on/off control for each of the four output load groups
- Main AC input power on/off switch and pilot indicator
- Switch guards to prevent inadvertent power off
- Secure outlet power cable retention

|
| Q6. |
What is the purpose of the Extension Bar? |
| A6. |
The Extension Bar plugs into the outlets on the Control Unit, and extends the outlet receptacles along the length of the rack to distribute power to the devices mounted in the rack. This feature allows you to mount the Bars in such a way that you need not run long power cords down the entire length of the rack. This not only helps you reduce cable clutter, but also gives you easy accessibility to the outlet receptacles. A maximum of up to 4 Bars may be plugged into one Control Unit, and each Extension Bar has up to 7 outlet receptacles.

| Form factor, mounting options and functionality |
| Q1. |
Is the Modular PDU 1U or 0U? |
| A1. |
Modular PDUs may be mounted in 0U, 1U. All mounting hardware required to mount the Modular PDUs in the HP 9000 and 10000 series racks, is shipped with the unit. For third party racks, please refer to the compatibility section. |
|
| Q2. |
Where can I mount the Extension Bars? |
| A2. |
Extension Bars can be mounted directly to the rack-frame or to the rack extension unit. |
|
| Q3. |
How many outlet receptacles does each Extension Bar have? |
| A3. |
Each Extension Bar has a maximum of up to 8 outlet receptacles. For more details, please refer the product QuickSpecs. |
|
| Q4. |
What is the benefit of load groups? How many load groups are available in the Modular PDUs? |
| A4. |
Four load groups are offered on each Control Unit. If by accident, your load connected on one group goes down, then the remaining 3 load groups will not necessarily be affected. They behave as 4 separate branch circuits. (However if the main input power in the Control Unit goes down, then all the connected devices will go down)
|
|
| Q5. |
What hardware do the Modular PDU products support? |
| A5. |
HP Modular PDUs are optimized for the HP 10000 Series racks. They support all HP rack mountable servers, storage, and other rack mount options.
Modular PDUs can be installed in 3rd party racks (with standard EIA19" vertical rails) in a 1U configuration. The Control Unit mounts in1U configuration only. And to mount the Extension Bars, you need to order a separate option kit PN 310777-B21.
|
|
| Q6. |
What mounting kit comes standard with the Modular PDUs? What other mounting options are available? |
| A6. |
The Modular PDUs ship standard with 0U and 1U mounting brackets for the Control Unit. Mounting hardware for the Extension Bars is also provided in the kit. This mounting hardware allows customers to mount the Modular PDUs (1U/0U configuration) in the HP 9000 and 10000 series racks. |
