Why Use Blanking Panels in Server Racks?
Unused rack openings can create an easy path for hot exhaust air to circulate from the rear of a cabinet back toward server air intakes.
This recirculation can contribute to:
- Elevated equipment inlet temperatures
- Hot spots within racks
- Uneven cooling
- Unnecessary mixing of hot and cold air
- Reduced cooling-system efficiency
Installing blanking panels closes these unused spaces and helps maintain separation between the conditioned intake air at the front of the rack and the hot exhaust air leaving equipment at the rear.
Upsite specifically designs HotLok rack-sealing products to reduce high intake-air temperatures by preventing exhaust-air recirculation.
Tool-Free Snap-In Installation
The HotLok 10031 installs directly into compatible rack openings without screws, cage nuts, or tools.
Simply position the blanking panel in an unused 1U opening and snap it into place.
Built-in finger grips make the panel easy to remove when rack space is needed for new equipment.
This makes HotLok panels particularly useful in data centers where rack configurations change frequently and blanking panels must be added or removed as servers, switches, and other equipment are deployed.
Designed to Improve Rack Sealing
HotLok panels incorporate cantilevered sealing vanes designed to reduce gaps between adjacent blanking panels and installed IT equipment.
This helps create a more continuous rack face instead of simply covering the center of an unused opening while leaving airflow gaps around the panel.
Effective rack sealing is especially important in:
- Hot-aisle/cold-aisle environments
- Contained aisles
- High-density racks
- Cabinets with significant unused rack space
- Data centers working to improve airflow management
Easy Storage Between Installations
The HotLok 1U panels use an interlocking design that allows multiple panels to be stacked together when they are not installed.
Upsite specifies that the 1U panels can stack up to 10 panels high, making them easier to store and transport within the data center.
This can be especially useful for facilities teams that keep spare blanking panels readily available as rack configurations change.
1U vs. 2U HotLok Blanking Panels
HotLok blanking panels are available in multiple sizes depending on the amount of unused rack space that needs to be sealed.
| Model | Rack Space | Width | Best Use |
|---|---|---|---|
| HotLok 10031 | 1U | 19″ | Individual 1U openings and flexible rack configurations |
| HotLok 10033 | 2U | 19″ | Larger unused rack openings |
Use the 1U HotLok 10031 when maximum flexibility is important or when filling individual rack-unit openings.
The 2U HotLok 10033 can be useful for larger contiguous openings and is sold in multiples of five.
Need a 23-Inch Blanking Panel?
The HotLok 10031 is designed for standard 19-inch racks.
For compatible 23-inch equipment racks, see the HotLok 10177 1U 23″ Blanking Panel.
Frequently Asked Questions
What does a server rack blanking panel do?
A blanking panel seals unused rack spaces to help prevent hot exhaust air from recirculating toward equipment air intakes and to reduce unwanted bypass airflow through the rack.
What size is the HotLok 10031?
The HotLok 10031 is a 1U, 19-inch blanking panel measuring approximately 19″ wide × 1.75″ high.
Does the HotLok 10031 require tools to install?
No. The panel uses a tool-free snap-in design and does not require screws, cage nuts, or additional mounting hardware.
Will it fit a standard server rack?
The HotLok 10031 is designed for compatible 19-inch EIA-310-E rack openings.
What material is the HotLok 10031 made from?
The panel is manufactured from high-impact polystyrene and has a UL 94 HB fire rating.
How many panels do I need to order?
The HotLok 10031 is sold in multiples of 10.
Is there a 2U version?
Yes. For larger openings, see the HotLok 10033 2U Blanking Panel.
Improve Rack Airflow with HotLok
Blanking unused rack spaces is one of the simplest ways to improve airflow management inside IT cabinets.
The HotLok 10031 provides a reusable, tool-free solution for sealing individual 1U openings while allowing panels to be quickly removed as new equipment is installed.
