EHRM Infrastructure Readiness - Zone Power Distribution Installation Guide

OIT Infrastructure Standards for Telecommunication Spaces (ISTS) v. 3.0

This package follows the OIT ISTS Design Guide convention of using contrasting Blue and Yellow color highlights to emphasize diverse power sources and paths.

Relevant extracts from the OIT ISTS Design Guide have been included. The complete Design Guide pages and can be found in Appendix B of ISTS 3.0 published in the OIT Technical Reference Model (TRM) database and on the VHA CFM Technical Information Library (TIL). Additional discussion of Zone-based three-phase power distribution to the rack/cabinet level can be found in OIT ISTS 3.0, Section 4.2, Electrical Power and Grounding Standards, beginning on Page 21.

Each IT equipment set will require a specific configuration of electrical power to be delivered to its IT cabinets, compliant with OEHRM Site Infrastructure and End User Requirements (SIEUR) and with OIT Infrastructure Standards for Telecommunication Spaces (ISTS). This document clarifies circuit requirements, materials, and task responsibilities which are common across most installations. Details which are specific to each particular installation, such as compatible brands of circuit breakers, cannot be determined at this level and are left for qualified local staff to specify.

OIT Design Guide Sheet 18 - 30A Zone PDU Power Distribution This sheet explains how to implement Zone power distribution among multiple cabinets in a standardized cabinet row.

OIT Design Guide Sheet 23 - Equipment Bonding and Grounding This sheet describes how to properly connect IT devices, enclosures, and other infrastructure to a common signal ground, in accordance with J-STD-607.

30 Amp Zone PDU Detail - Circuits and Connections These diagrams and schematics describe three-phase 30A 120/208V L21-30 circuits supporting Zone PDU inputs and Rack PDU connections to Zone PDU outputs.

Zone and Rack Power Distribution Detail - JSA and FDS Cabinets These cabinet-based schematics show cable routing and connections among Zone PDU's, Rack PDU's, and IT Equipment Power Supply Units (PSU).

Power Cable Examples These diagrams give visual examples of various power distribution and interconnection cables and connectors.

Contents

Material Lists for JSA and FDS Power Distribution These lists call out the components the facility is responsible for acquiring and installing. For clarity, JSA and FDS materials are listed separately.

Task Matricies for JSA and FDS Installation These matrices clarify power chain connections, installation tasks, and responsibilities for performing them. For clarity, JSA and FDS tasks are listed separately.

Frequently Asked Questions Frequently Asked - and Answered - Questions.

The enclosed material provides supplemental details and explanations to local facility OIT and Engineering staff when preparing for EHRM hardware deployments. As discussed during the HEFP Scoping sessions, EHRM hardware will consist of a Joint Security Architecture (JSA) IT equipment set and a Forward Deployed Services (FDS) IT equipment set.

DISTRIBUTION SYSTEM BACK TO THE UPS OR TRANSFORMER WINDING

POLE. THIS INCREASES THE EFFICIENCY OF THE POWER DISTRIBUTION

SYSTEM AND SUPPRESSES HARMONICS IN THE SYSTEM.

Frequently Asked Questions (Zone Power Distribution) This is all too complicated. Make it simple, and just tell me what I need to buy.

See Materials list attached.

However, your detailed understanding of how these components connect will still be necessary for a successful deployment.

This diverse path and redundancy stuff is confusing. Why do we need it?

The intent is to provide highly available (2N Redundant) power to IT devices. What that means is that either path can carry the entire load if the other path is lost.

Under normal operation, the two paths will share the load and neither path should exceed 50% of its rating.

My room has only one UPS and you're asking for power path diversity, which I can't provide. What do I do?

This is a common issue in older power chain designs. Make the circuits as diverse as possible downstream of the single UPS. You should NOT use workarounds such as convenience outlets ("wall power") and extension cords to provide a second path. Future construction should provision a properly sized and matched second UPS to permit full path diversity. This limitation should have been (or will be) identified during your HEFP scoping session, and construction funds allocated to remedy it.

You're asking for two circuits, but only one Zone PDU for each stack. Doesn't using only one Zone PDU break your path diversity?

As shown in multiple diagrams, the Zone PDU is a single enclosure which is designed to accept two input circuits from diverse power distribution sources and to distribute power to multiple outputs while preserving path diversity. Internal design avoids Single Points of Failure (SPOF).

With four L21-20R outputs, two from each source, each Zone PDU can support two Standard Density cabinets with 2N power redundancy at 3.5 kW apiece.

Your Zone PDU power values don't make sense. Derated to 80% per NEC/NFPA, each L21-30P circuit path can provide 8640 Watts, but each pair of L21-20 Rack PDU's they support are rated for 5760 Watts apiece. So it looks like you will overload the distribution circuits. How do you explain this?

We do not expect to load the L21-20 Rack PDU's to their full rated capacity. Standard Density cabinets in legacy spaces are scaled for an expected load of 3500 Watts (3.5 kW) per cabinet due to other constraints. A single 8640 Watt circuit can support two cabinets at a combined 7000 Watts with reserve for variations, contingencies, and inefficiencies.

The JSA and FDS devices referenced here were distributed among cabinets to keep their expected loads below the 3.5 kW per cabinet threshold.

I need to [want to] use a completely different power distribution circuit/voltage/scheme for this equipment. Can't I just ignore all this and do it my way?

Briefly, No.

This represents OIT's standardized power distribution topology to support increasingly power-hungry IT devices, and it is what the EHRM systems have been designed to use. It has also been coordinated with VHA Engineering and published interally and externally.

If you believe you have a unique power situation or limitation, please contact your VISN EHRM PM or HEFP for further discussion.

The newest Infrastructure Standards for Telecommunication Spaces published on the TIL uses 60A direct-wired Zone PDU's to support up to three cabinets. Why aren't you following that design? Can I do it that way?

The EHRM hardware deployment was designed before the newest version was published and requires no more than two cabinets together. The 30A Zone PDU is still used within the newest ISTS 3.0 version to support one or two cabinets. The 60A Zone PDU's are scaled to support higher power densities per cabinet (5 kW/cab) in conjunction with more rigorous room analysis and construction.

You are free to use 60A Zone PDU distribution if you desire; follow the ISTS 3.0 and Design Guide templates for branch distribution details.
