HP Cisco MDS 9124 HP StorageWorks C-Series Fabric Switches for NX-0S 4.1(3a) R - Page 8

ADDITIONAL MOUNTING REQUIREMENTS C-series Fabric Switches can be installed in all HP standard racks. Please note the following restrictions: Side-Rail Rack-Mounted Options All side-rail rack-mounted options must have a minimum of four (4) inch clearance distance above or below the switch chassis for the C-series MDS 9500 Series Multilayer Directors and MDS 9200 Series Multilayer Fabric Switches. Side-rail rack-mount options include HP zero-U options, KVM switches and power distribution units (PDUs). The minimum distance between the top of the switch to the bottom of any side rail rack mounted option, or the bottom of the switch and the top of the side rail rack mounted option must be at least four (4) inches. HP Rack Cabinet Support For standard HP Rack Cabinets with closed side panels, you must have at least two-and-one-half inches (2.5 in.) (6.4 cm) of air space between the rack walls and the MDS 9200 and 950x chassis air vents. For the MDS 9513, you must have at least four inches (4.0 in.) (10.16 cm) of air flow between the rack walls and the director. If the air space does not meet these minimum requirements, remove the rack side panels. The HP 10842 (800mm wide, 42U) Rack Cabinet is ideally used as a networking rack accommodating primarily switching equipment. It can also be used as a server/switch rack. The 10842 rack is a wider version of the 42U 9000 series rack at 800 mm/31.3 in width. This added width provides approximately eight additional inches of room outside of the internal mounting rails, which can be used for cabling. Other Types of Cabinets When the C-series MDS 9500 Family Multilayer Directors and MDS 9200 Family Multilayer Fabric Switches are installed in racks other than those mentioned above, including any open sided racks, the following guidelines must be followed to prevent overheating: • Closed-sided racks must have at least two-and-one-half inches (2.5 in.) (6.4 cm) of air space between the walls and the 9200 and 950x chassis air vents. The MDS 9513 must have at least four inches (4.0 in.) (10.16 cm) of air flow between the rack walls and the director. • Open-sided racks (for example, racks commonly used for telecommunications equipment), with switches installed side by side must have at least six inches (6 in.) (15.2 cm) of air space between two different switch chassis • All rack types must have nothing to obstruct the cooling vents with side mounted options Cabling When cabling any C-series product, the front door on all HP standard racks should be removed to allow for adequate cable space; this will ensure a safe bending radius on all fibre channel cables. This is especially pertinent in high port density (Director) installations.
