Accessories

NetShelter CX

Dust Filter Pack NetShelter CX 18U & 24U 2 Small Filters

This Dust Filter Pack for the NetShelter CX allows the user to reduce the airborne particles entering the enclosure. The reticulated plastic filter material is washable and easily removed/replaced. Using the Dust Filter Pack on the NetShelter CX increases the Ingress Protection (IP) rating of the enclosure from IP44 to IP54 and reduces the risk of dust related equipment issues, such as overheating, system failure, and permanent data loss.

Includes: Installation guide, Mounting Hardware, Qty 2 - Metal filter lower cassettes, Qty 2 - Washeable filters for lower cassettes

NetShelter CX

Net Shelter CX Bolt Down Kit

This Bolt-down Kit is for the 18, 24 and 38U Netshelter CX product set. Of the 2 brackets in this set, one L-bracket affixes to the underside of the CX to pre-existing bolts. The other L-bracket affixes to the floor. Design is such that the 2 brackets can be fixed to the CX and floor first, and then the CX can be wheeled into place to secure the enclosure to the floor. Connection between the 2 brackets can be made using the nut & bolt hardware included, or by using a locking mechanism (not provided).

Please note reduction in internal cabinet depth in some rack units due to triangular protrusion of the exhaust fan module. Very deep servers or other such hardware must be installed above or below NetShelter CX 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:

NetShelter CX are designed to pass through a standard-size doorframe and are normally delivered fully assembled and ready to use. NetShelter CX can be broken down into component parts where access conditions are constrained. Please consult your NetShelter CX representative for details of delivery options in your area.

Warranty:

2 year general warranty against defective workmanship, inclusive of parts and labour

Rack Planning

Please note the following guidelines are for best installation and operation of hardware in NetShelter CX ranges of cabinets. Specific cabinet sizes are shown for illustration purposes below, but the principles extend to all NetShelter CX sizes.

Distribution of thermal load

24U Thernal 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 NetShelter CX 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 AR4024, which has 2 x fan modules. Model AR4018 has 1 x fan module, and model AR4038 has 3 x fan modules.

Location for very deep servers

24U Server layout

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.

b) 800 mm / 31.5"
c) 860 mm / 33.5"
d) 1010 mm / 39.5"

Floor space requirements:

Individual cabinets are designed to be pushed back flush against a wall. An air space of 200 mm / 8" on both sides of the cabinet is essential for normal operation.

Please note that the NetShelter CX as shown herein are not suitable for use with blade servers.

Power Specifications

Power consumption:

68 Watts total power consumption by the AR4024A itself, including cooling system

Internal power distribution:

12 x NEMA 3 pin sockets, arranged vertically
All power outlets in NetShelter CX feature surge protection

NetShelter CX power input connection:

NetShelter CX have power input via an 3 pin NEMA plug trailing lead for connection to an in-rack UPS or for connection to a wall outlet.

Grounding/Earthing:

All equipment installed within a NetShelter CX should have conventional grounding/earthing via power cables, but unlike conventional metal-case cabinets, the NetShelter CX 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 NetShelter CX 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.
