Frequently asked questions
HP POD frequently asked questions
Question Answer
Can I keep the HP POD on the trailer?
Yes, if you choose to lease the trailer from HP or if you
purchase your own trailer and have the HP POD installed on
your trailer prior to shipment. You must also:
•
Ensure that the site is stable and has been prepared
correctly for the additional weight of the trailer.
•
Provide a work platform to access exterior panels.
What cooling capacity ranges are
available in the HP POD?
The HP POD is capable of cooling rack-mounted components
consuming up to 600 kW of electrical power.
What electrical power capacity ranges are
available in the HP POD?
The standard HP POD is capable of powering components up
to 450 kW of electrical power.
The high density HP POD is capable of powering components
up to 600 kW of electrical power.
Can the level of heat removal be regulated
in proportion to the waste heat generated?
Yes, the control system automatically adjusts the air flow to
remove heat generated in the HP POD.
Does the HP POD require maintenance?
Yes, general maintenance is outlined in this document. Contact
HP service for additional information.
Does condensation form?
During normal operation some condensation might form, but
the condensation does not reach any rack-mounted
components or cause any damage. Excess condensation from
the heat exchangers is collected and drained through three
condensate drains across the rear of the HP POD. In most
cases, the condensation evaporates prior to reaching the
condensate drains.
How does the HP POD control humidity? The relative humidity is maintained between 30–70%.
If additional humidity is required (consistently below 30%),
consider installing the optional humidifier (on page 39).
Does the air flow within the HP POD
produce static electricity?
The humidity of the HP POD is maintained between 30–70%
to ensure that dangerous levels of static electricity cannot
build.
Is the HP POD weather resistant?
If there is an external leak, the HP POD is weatherproof and
has sufficient protection against the encroachment of water
inside the HP POD.
What happens if there is an internal leak?
If there is an internal leak, the water collects in the
condensation drain pans or the water main drain pan. The
additional water present in the condensation drain pan
triggers a Leak Detection alarm, sent over the ECS.
What will happen if water stops flowing to
the HP POD?
An EPO will occur automatically if the hot aisle temperature
exceeds 66°C (150ºF). If the ECS is connected to the site ECS,
a high temperature alarm will be sent to the ECS.
