Release Notes HP C-series FC Switches for NX-OS 6.2(3)(5697-2820,September 2013)

10 MDS 9000 Series Multilayer Director & Multilayer Fabric Switches Release Notes
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 SN8500C (MDS 9710) and SN8000C (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, 9700 and 9500 chassis air vents. For
the SN8500C (MDS 9710) and SN8000C (MDS 9500) 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 SN8500C (MDS 9700) and SN8000C (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 MDS 9200, 9700 and 9500 chassis air vents. The SN8500C (MDS 9710)
and SN8000C (MDS 9500) 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. Please consult the relevant Cisco Hardware
Installation Guide for further information.
