Installing a rack
INTRODUCTION TO THE VM600
Mk2
MACHINERY PROTECTION SYSTEM (MPS)
for an ABE04x system rack (see Figure 1-3, Case A) and 20 mm for an ABE056 slimline rack
(see Figure 1-4, Case A).
It is possible to prevent warm air flowing from one rack to another, by placing inclined plates
between them in order to deflect the airflow (see Figure 1-3, Case B for an ABE04x system
rack and Figure 1-4, Case B for an ABE056 slimline rack). When inclined plates are used with
VM600
Mk2
/VM600 racks, an inclined plate can also function as a non-flammable separation
barrier, if required (see 1.2.4 Instructions for locating and mounting). In addition, the space of
50 mm should be present below and above system racks (ABE04x).
If an ABE04x rack is assembled without empty slots between the MPS and/or CMS
processing modules/cards, it is recommended to use forced ventilation if the temperature of
the air flowing through the rack exceeds 40°C (104°F). If a 19″ × 6U rack has at least one
empty slot between each processing module/card, it is recommended to use forced
ventilation if the temperature of the air flowing through the rack exceeds 55°C (131°F).
In a case where forced ventilation by fan units is used, the spacing above, below and between
racks can be reduced to zero, providing that the airflow to/from neighbouring racks is
ensured.
Always ensure adequate spacing (minimum 50 mm for ABE04x racks) is
provided below and above a VM600
Mk2
/VM600 rack to allow proper natural
ventilation.
Failure to adhere to this requirement will cause overheating of the rack and
as a consequence will affect the correct operation of the system.
