Q: What is PRO2?
A: PRO2 is Server Technology's newest platform for CDU products. It meets needs that the previous generation cannot. This includes a shallower POPS form-factor (2.18"W x 2.25"D) compared to (1.75"W x 3.5"D), 25% higher vertical density of outlets on Switched products, more processor power and memory to support new features, and monitoring of both branch current and input current for all models. Additionally, the PRO2 design has been put through more extensive design, test and validation procedures than any previous generation. This design review resulted in even more robust quality than our already best-in-class product. Improvements include locking cables for internal communication and low-voltage busses to prevent high-vibration connection loss, and higher noise immunity for the internal logic. -
Q: What is PRO1?
A: In short, it is a variable reduction of hardware features from PRO2. It uses the same network card so much of what follows applies to both. See the Technical Note for more details -
Q: Will PRO2 replace the previous generation of CDU products?
A: Yes, the previous generation of CDU are mostly transitioned at time of this writing. -
Q: What new features are added to the PRO2 line?
A: Features include redundant network power with hot-swap network card, branch current monitoring, faster secure connections, PIPS standard, on-board file system, shallow form-factor for POPS, capability to link 3 expansion units, and additional alarms and alarm levels. -
Q: What happens to communication if power is lost to the Primary PRO2 unit?
A: Network integrity is ensured when power is lost to the Primary unit as power is fed back from the first link unit's cable to ensure uptime and manageability of the link CDU. -
Q: Can the network interface card be hot-swap replaced in the field without special programming steps?
A: Yes, the network interface card can be replaced by the user even with power applied. Programmed settings are maintained within the PRO2 unit and no additional programming is needed for the new card. -
Q: How is firmware upgraded?
A: The firmware can be upgraded by an FTP server as before, but now it can also be directly uploaded through the web GUI or by an SFTP or FTP client. -
Q: Is the firmware backward compatible with the previous generation of CDU products?
A: No, the PRO2 firmware starting at v8.0 cannot be installed into the previous generation of CDU products with v7 FW and below. -
Q: Is the SNMP MIB backward compatible with the previous generation of CDU products?
A: No, the PRO2 has a new MIB based on a new hardware architecture that more accurately reflects all of the possible combinations of units, cords, lines, phases, over-current protectors, branches, outlets, and sensors. The MIB and OID are posted on our web site at https://www.servertech.com/support/sentry-mib-oid-tree-downloads. Also, there is a technical note explaining the differences between our old MIB and the PRO2 for customers and solution partners that have integration questions. -
Q: What files are available when logged into the PRO2 unit?
A: The new on-board file system of the PRO2 series has the FTP.ini, SNTP.ini, Network.ini, and config.bak files as we are used to in the previous generation CDU. Additionally, the MIB and OID Tree files are downloadable from the PRO2 unit. All of these files are accessible through FTP as before, and now through the web GUI and SFTP. -
Q: What is the benefit of Branch Current Monitoring?
A: Branch Current Monitoring is now added to the PRO2 as a standard feature. This allows for thresholds to be configured on the branch circuit protection to alert before breaker/fuse trip. -
Q: Are there alerts when breaker/fuse branch circuit protection trips?
A: Yes, alerts via SNMP and email are sent when breaker/fuse trips on all PRO2 models. -
Q: What are the additional alarms available in the PRO2 line?
A: PRO2 adds a second (warning) level to the alarms. Now set thresholds on low and high branch load, low and high cord power, low and high cord apparent power, low cord power factor, high 3-phase out-of-balance, low and high line load, low and high outlet load, low and high outlet power, low outlet power factor, low and high phase voltage, low phase power factor, low and high temperature, and low and high humidity. All threshold setting now have finer resolution (e.g. 0.1A instead of 1A) and configurable hysteresis. -
Q: How has outlet identification changed?
A: Numbering is not tied to the branch or phase but is listed as 1 to n for outlets, branches, OCPD, etc. Each outlet has a unique number – for example, a 30-outlet PRO2 unit has outlets numbered 1 to 30 whether single-phase or three-phase. Additionally, every 3-phase PRO2 unit uses L1, L2, and L3 as the input line indicators instead of some using X, Y, and Z. Finally, branches are always called 1, 2, 3, etc. instead of some using XY, YZ, and ZX. -
Q: Are the same temperature/humidity probes supported?
A: Yes, the PRO2 series uses the same probes as the previous generation of products. All link/expansion units also provide ports for two probe sensors just as the primary units do. -
Q: Is an EMCU supported?
A: Yes, the first link port on the primary unit supports an EMCU. The redundant network power feature is supported through an EMCU. -
Q: How does the new multi-linking feature work?
A: The first expansion unit works as before. The second and third expansion units attach to an optional module which connects to the “Auxiliary/Bluetooth" port. This optional module provides two more link ports and a Bluetooth port. -
Q: Will SPM fully integrate with the PRO2 line?
A: Version 6.0 of SPM or greater supports PRO2 units. -
Q: Are the same custom colors and cord lengths available for PRO2 products?
A: Yes, custom colors and cord lengths follow the same rules as before. -
Q: Will the existing bracket designs work with the PRO2 series products?
A: Most of the existing bracket designs will continue to work with the 2.2" wide PRO2 series products, but each case should be analyzed by Server Technology Sales Engineers. -
Q: Do the PRO2 series products support the P-Lock type cords and EZip products?
A: Yes, PRO2 continues to support P-Lock type cords and EZip products as before. -
Q: Are serial-port-connected integrations with Avocent and MRV products supported.
A: No. Existing Avocent and MRV firmware only supports the version 7.0 product architecture. - Q: What is the operating temperature rating?
A: The standard for PRO2 is 60C, and will be met whenever possible. - Q: Are RF Code sensors supported?
A: Yes, RF Code has new sensors for these PDUs. - Q: Is Cisco EnergyWise supported?
A: Yes, it is supported. - Q: Is the local LED display invertible?
A: Yes, all PRO2 products have auto-flip invertible displays.
HDOT PRO2 Switched
- Q: What is the significance of this product?
A: Server Technology has added POPS (Per Outlet Power Sensing) to its industry leading and award winning HDOT PRO2 Alternating Phase Rack PDUs. This product expands upon the most innovative power product on the market, with solutions for density, capacity planning and uptime in the modern data center. - Q: What is HDOT?
A: To combat the limited physical space that PDUs compete for in the data center rack, Server Technology developed High Density Outlet Technology (HDOT), the smallest form factor PDU which significantly increases real estate in the back of the rack by fitting as many as 42 C13's in a 42U high network managed PDU device—that's over 20 percent smaller than a comparable PDU using standard outlets. This was accomplished by removing the shell that surrounds commercially available C13 and C19 outlets, and creating a series of multi-outlet modules in a variety of configurations that fit into a common monolithic metal enclosure. To exploit this design and the thousands of variations it makes available, Server Technology developed a quick turn manufacturing process that provides short lead times for PDU's with the exact combination of C19 and C13 outlets in the locations where the customer needs them. The HDOT design implements high native cord retention of over 10 pounds pull strength, reducing or eliminating the need for custom and costly ancillary locking cord devices. With increasing outlet density comes increased power, and potentially increased heat. HDOT is manufactured with robust high temperature materials carrying a UL94 V-0 flame rating, making these outlets ideally suited for the harshest data center environments. - Q: What is Alt-Phase?
A: To simplify load balancing and cable management, Server Technology offers PDUs with Alternating Phase outlets, which distributes phases on a per receptacle basis (rather than in discrete separate banks), providing tangible benefits in the form of shorter cable runs, resulting in better airflow, easier load balancing, and greater efficiencies. Prior to the advent of HDOT, Alternating Phase products were impractical to build due to the low outlet density inherent with discreet commercially available outlets. - Q: What is PRO2?
A: PRO2 is a flexible and feature rich hardware and firmware platform, higher on board compute power, all modern security protocols, redundant features, and advanced customization all built into the product. The new PRO2 architecture is ideal in any situation where reliability and uptime are important, particularly in high temperature and high security applications. With PRO2, customers can maintain uptime with access to current data and future trends. See the PRO2 FAQ for more detailed information. - Q: What are Switched outlets?
A: With the ability to turn ON and OFF or reboot outlets individually or as a group, certain features become possible such as, outlet lock-out, power-up sequencing that reduces the concern of power-up inrush, and our optional smart load shedding. - Q:What is POPS?
A: Per Outlet Power Sensing provides +/-1% billable-grade accuracy for energy consumption at each outlet for typical data center equipment loads. POPS also includes current, voltage, active power, apparent power, power factor, and crest factor at each outlet. This provides for the ultimate in efficiency and capacity analysis. Also, use alerts for high current, high/low voltage, and low power factor for extended visibility. - Q: What configurations of this are available?
A: Tens of thousands of variations are available for the HDOT Alt-Phase PRO2 rack PDU. See the Build-Your-Own PDU website at byopdu.servertech.com to configure your perfect Switched POPS, Smart POPS, Switched only, or Smart only high-density rack PDU.
