Cisco AJ732A - MDS 9134 Fabric Switch Release Note page 7

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. Please consult the
relevant Cisco Hardware Installation Guide for further information.
