100 mm / 6" behind the cabinet is essential for normal operation.
2: Baying model PSE18 cabinets together reduces the maximum recommended thermal load in each cabinet from 1.2 kW to 1 kW.
3: In bayed cabinets, it is essential that the thermal load is distributed evenly between the cabinets.

Accessories
Heavy-duty vertical cable management fit-out
Where extensive network cabling is being installed in a Kell Systems ComputerVault Pro, this option is recommended. The front cable trays are replaced with columns of steel cable management loops mounted on either side of the front of the 19" rack, enabling tidy and secure management of hundreds of Ethernet cables around patch panels and switch gear in the front of the data cabinet. This option cannot be retro-fitted and is only available at time of first ordering the ComputerVault Pro.
| For ComputerVault Pro model | PSE18 |
| Part code | VCM18 |
| Number of cable loops | 4 per side |
Horizontal cable management panels
For tidy and secure management of cables and jumpers around patch panels and switch gear in the front of the server cabinet.
| Part code | HCM |
Static server rails
Where tower servers are to be installed in a Kell ComputerVault Pro, these simple and inexpensive rails provide an alternative to costly manufacturer´s 19" rack mount conversion kits. Fits modern tower servers of the approx. 450 mm standard height. Please measure the height of your tower server and check with your Kell representative if you are unsure of compatibility.
| Part code | SSR |
Baying kit for linking ComputerVault Pro together
Allows adjacent Kell ComputerVault Pro to be linked together with the cabinets open to each other internally, without compromising the noise reduction performance. Note that baying ComputerVault Pro together reduces the maximum recommended thermal load per cabinet by about 20%, and the thermal load should be distributed evenly between the cabinets. Please refer to the Kell ComputerVault Pro Product Guide for more details, or consult your Kell Systems representative if in doubt. This option can only be retrofitted to v7.6 ComputerVault Pro models delivered from January 2008 onwards.
| For ComputerVault Pro model | PSE18 |
| Part code | BK18 |
Spare Kell ComputerVault Pro fan module
The Kell Systems exhaust fan module is common to all ComputerVault Pro and attaches to the back of the server cabinet with push-fit clips. It can be changed in a couple of minutes with no tools and no requirement for technical knowledge. ComputerVault Pro fan failures are extremely rare, however should you be deploying a Kell ComputerVault Pro in an overseas location to which shipping of spares can take time, a locally-held spare provides restoration in minutes.
| Part code | KFM |
Cantilever equipment shelves
Kell cantilever equipment shelves fix to the front rack posts via 4 x conventional rack screws and cage nuts (not supplied). Depth 400 mm. They provide a suitable rack-mounting platform for smaller non-rack-mounting devices such as modems, routers, switches, tape drives, KVMs etc. They are suitable for use with some mini-desktop pcs, but should not be used to support servers (see Static Server Rails above).
| Rack height of shelf | 2U | 3U | 4U |
| Part code | CS2 | CS3 | CS4 |
Dust filter pack
Kit includes removable, washable dust filters for all ComputerVault Pro air intake apertures. Easy to retrofit with no tools required. Please note that dust filter packs are standard fit on BladeVault™ cabinets
| ComputerVault Pro Model | PSE18 |
| Part code | DF18 |
High security code-entry door lock
Kell ComputerVault Pro have key-entry tamper locks as standard. This option is for higher security applications and/or where there is concern that keys may get lost.

Model PSE18 Plan Section
PSE18 External views
PSE18 side section
Please note reduction in internal cabinet depth in some rack units due to triangular protrusion of Kell exhaust fan module. Very deep servers or other such hardware must be installed above or below Kell fan modules.
Dimension key:
a) 775 mm / 30.5"
b) 800 mm / 31.5"
c) 860 mm / 33.5"
d) 1010 mm / 39.5"
e) Indicates soundproofed cable entry / exit pathway (acoustic materials not shown). The cable port is large enough to accommodate several hundred Ethernet cables and has a removable top cover. The design is such that pre-terminated patch panels can be installed effortlessly, with no need for de-termination and re-termination.
Delivery and Aftercare
Delivery:
ComputerVault Pro are designed to pass through a standard-size doorframe and are normally delivered fully assembled and ready to use. ComputerVault Pro can be broken down into component parts where access conditions are constrained. Please consult your Kell Systems representative for details of delivery options in your area.
Warranty:
1 year general warranty against defective workmanship, inclusive of parts and labour
3 years warranty on fan systems
Rack Planning
Please note the following guidelines are for best installation and operation of hardware in Kell’s ComputerVault Pro and ComputerVault Pro RM ranges of cabinets. Specific cabinet sizes are shown for illustration purposes below, but the principles extend to all ComputerVault Pro and ComputerVault Pro RM sizes.
Distribution of thermal load
Avoid clustering hot-running devices such as servers, dense RAID arrays and large VoIP switches in one part of the rack. Distribute the thermal load evenly up and down the rack such that each Kell fan module supports an equal amount of the thermal load, or as close to it as possible. Please allow a minimum 1U gap between all hot-running devices.
The cabinet shown in this example is the model PSE24, which has 2 x fan modules. Models PSE12 and PSE18 each have 1 x fan module, and model PSE38 has 3 x fan modules.
Location for very deep servers
Each fan module has a triangular metal section protruding slightly into the cabinet (please also see side section drawings in technical drawings section). This does not create an issue for installation of most equipment, but to allow for ample cabling space to the rear, deep servers are generally best installed in the rack spaces above and below these triangular metal protrusions.

Dimension key: a) 775 mm / 30.5" b) 800 mm / 31.5" c) 860 mm / 33.5" d) 1010 mm / 39.5" |
Baying cabinets together
When the optional baying kit is used to link cabinets together, the rear sections of the cabinets are open to each other as shown here.
Thermal load in bayed cabinets
When installing hardware in bayed cabinets, distribute hot-running devices evenly between the cabinets as shown.
Please note that standard Kell Systems ComputerVault Pro as shown herein are not suitable for use with blade servers. Please refer to Kell's BladeVault™ solution for deployment of these types of devices.
Power Specifications
Power consumption:
19 Watts total power consumption by the model PSE18 itself, including cooling system
Internal power distribution:
All power outlets in Kell Systems ComputerVault Pro feature surge protection
UK & Europe: 7 x IEC 320 C13 (10 A / 220/240 V) sockets, arranged vertically
USA/Canada: 7 x US 3 pin sockets, arranged vertically
Rest of world: 7 x IEC 320 C13, arranged vertically, unless specified otherwise
ComputerVault Pro power input connection:
All Kell ComputerVault Pro have power input via an IEC 320 C14 (male) trailing lead for connection to an in-rack UPS, and an extension cable for connection to a wall outlet. User may choose the preferred way to connect. The extension cables are configured as follows:
UK: IEC C13 female trailing socket to standard UK 3-pin plug
Europe: IEC C13 female trailing socket to Schuko 3-pin plug
USA/Canada: IEC C13 female trailing socket to standard US 3-pin plug
Custom: IEC C13 female trailing socket to any user-specified 3-pin plug
Grounding/Earthing:
All equipment installed within a Kell Systems ComputerVault Pro should have conventional grounding/earthing via power cables, but unlike conventional metal-case cabinets, the ComputerVault Pro itself has no requirement for additional grounding/earthing in the form of ground strapping or pipe earthing etc. The cabinet shell is constructed entirely from non-conductive materials and the rack is completely isolated from outside contact.
Anti-static measures:
No anti-static measures are required in a Kell Systems ComputerVault Pro installation. The rack has full electrical isolation and is not susceptible to static build up that can originate in conventional metal racks by contact with artificial carpet or other flooring materials.
