Enclosure Doors
Enclosure Doors
System enclosures have a short enclosure door on the appearance side. When closed,
it reduces electromagnetic interference (EMI) and ensures maximum cooling for
components inside the enclosure. You must keep the appearance-side enclosure door
closed during normal operation of the server.
Starting with the NonStop S76000 and S86000, servers are equipped with tall doors on
the appearance side and service side as part of the visual image package. (See Visual
Image Package on page 4-61.)
A short service-side door is also available.
When both fans are operating, you can safely open the appearance-side door for a
limited time to perform maintenance or upgrade procedures. For the time that a system
can operate before overheating with the appearance-side door open and only one fan
operating, see Maximum Time That an Appearance-Side Door Can Be Open on
page 4-13.
All doors are mounted on the enclosures using hinge pins attached to the door
assembly.
