Wiring Closet – General Description Wiring Closet - Critical subsystem of a network environment

Small Room with Servers/Telecom/Electrical Equipment/ UPS Floor Space is a Premium: <100 ft2

Contents: 1 – 3 Equipment Racks Heat Load per Rack: 1.0 - 2.0 kW Avg. Typical Cooling: None or Building Cooling During Day Remote location of building Security: Medium

Locked Door and/or Locked Cabinet

“The average wiring closet contains $150,000 - $300,000 of equipment and a typical small server room often houses more than three times that amount.”

- Mitch Medford, NetBotz CTO

Electronic Equipment Trends Power = Heat

Servers Blade Servers

Smaller & More Powerful IP & VOIP Telecom Equip

High-powered switches and equipment

Low-powered legacy Requires UPS support

Overheated IT equipment Reduced Life / Hardware Damage Reduced Reliability Slower Network Costly System Downtime General Rule

Every 10°C temperature rise in nominal temperatures produces a 50% reduction in the lifetime and long-term reliability of IT hardware - MIL-HDBK 217 / Arrhenius Models

LAN Room Heat Problem Businesses dependent on computers and telecom equipment

for day-to-day operations Need to keep IT equipment cool

ASHRAE Technical Committee 9.9 Thermal Guidelines

Inlet Temperatures Costly to rely on building A/C

Data Centers Upper range temperatures acceptable

Tight controls/monitoring Redundancy

LAN Room/Wiring Closets Temperatures in the upper 60Fs/lower 70s are practical

Looser controls/monitoring No redundancy

Cooling Load Determining the cooling load in a wiring closet

Incremental load from equipment Nameplate rating

Usually overstated ASHRAE TC 9.9: Load during operating conditions

Not yet adopted by manufacturers Determine cooling load from UPS load

Load from all equipment connected to the UPS Dependent on day and time

Monitor over a period time to get worst case scenario Other sources of heat

Lights/windows/outside wall/etc…

Electrical power to rejected heat conversion 1 kW = 3,413 Btu/hr.

12,000 Btu/hr = 1 ton of A/C

Cooling Solutions & Best Cooling Practices Cooling Solutions

Primary cooling for IT equipment LAN Room/Wiring Closet is not air conditioned

Nights & Weekends when building a/c is off Shut down building a/c when people are not in the building

Supplemental Cooling Added denser IT equipment Seasonal: Summer or Winter

Redundancy / Emergency backup to primary cooling Planned or unplanned shut downs: Inexpensive insurance plan

Best Practices Spot Cool vs. Traditional A/C

Managing Air Movement Direct cold air to front of server: Airflow = Front to Back Telecom equipment: Airflow = Side to Side

Do not cool down the entire room Back of the rack: Up to 36°F Hotter

Use blanking panels Unoccupied rack space: Recirculation of warm air

Organize cabling Maximize airflow
