8 Quick Start Guide: 7300 Series Modular Data Center Switches
Tools Required for Installation Chapter 2: Preparation
• All front panel modules have the same color handles.
• Rear panel modules must have different color handles than front panel modules.
Orient the switch to assure that the air intake modules face the cool aisle. If the airflow direction is
not compatible with the installation site, contact your sales representative to obtain modules that
circulate air in the opposite direction.
• Rack Space: Install the switch in a 19" rack or cabinet. The switch height depends on the switch
model, as specified in Table 1-1 on page 2 . Verify that the linecard and supervisor removal
clearance ( Figure 2-1 on page 7 ) provide adequate space for the power and data cables that
connect to the switch.
When mounting the switch in a partially filled rack, load the rack from bottom to top, with the
heaviest equipment at the bottom. Load the switch at the bottom if it is the only item in the rack.
The accessory kit provides mounting brackets for four-post racks. Contact your sales
representative to obtain two-post mounting racks.
• Power Requirements: Power requirements vary by switch. Refer to Table 1-1 on page 2 for
information regarding your specific system.
Multiple circuits provide redundancy protection. The switch uses power cables that have an
IEC-320 C19 plug. The accessory kit provides IEC-320 C19 to C20 power cables.
Important! All power input plug-socket combinations must be accessible at all times; they provide the primary
method of disconnecting power from the system.
• Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and
foreign objects are not drawn into the ventilation holes. Verify these guidelines are met:
• Clearance areas to the front and rear panels allow for unrestricted cabling.
• All front and rear panel indicators can be easily read.
• AC power cords can reach from the AC power outlet to the connectors on the front panel.
Important! Disconnecting power to all input sockets is required to completely power off the unit.
2.2 Tools Required for Installation
Each switch provides an accessory kit that contains parts for installing the switch into a four-post rack.
Two-post rack mount parts are available through your sales representative. Accessory kits do not
include screws, nuts, or bolts for attaching the switch to a conventional rack.
In addition to the accessory kit, the following tools are required to install a modular switch:
All Racks
• Mechanical device capable of lifting chassis being installed (chassis weight listed in Table 1-1 on
page 2 ).
Two-Post Conventional Rack
• Screws or rack mounting nuts and bolts.
• Screwdriver.
Four-Post Tool-less Rack
No additional equipment required.
