Installation Guidelines
When determining where to place the switch, make sure to observe these requirements and guidelines. Use these requirements and guidelines with the information in "Reference."
•Temperature around the unit does not exceed 113°F (45°C).
Note If the switch is installed in a closed environment or in a multirack assembly, the temperature around it might be greater than normal room temperature.
•The heat sinks and the bottom of the Catalyst Express 520-8PC-K9 switch might be hot to the touch if the switch is operating at its maximum temperature 113°F (45°C) and is in an environment that exceeds normal room temperature (such as in a closet, in a cabinet, or in a closed or multirack assembly).
•Airflow around the switch and through the vents is unrestricted.
Note We strongly recommend that you allow at least 3 inches (7.6 cm) of clearance around the ventilation openings to prevent airflow restriction and overheating.
•Do not stack switches or place switches side-by-side unless they are separated on all sides by at least 3 inches (7.6 cm) of clearance from each other.
•Do not place any items on the top of the switch.
•Allow at least 1.75 inches (4 cm) of clearance above each switch in the rack.
•Do not wall-mount the switch with its front panel facing up or sideways. According to safety regulations, wall-mount the switch with its front panel facing down to prevent airflow restriction and to provide easier access to the cables.
•Clearance to front and rear panels is such that
–Airflow around the switch and through the vents is unrestricted.
–Front-panel LEDs can be easily read.
–Access to ports is sufficient for unrestricted cabling.
–AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures.
•Cabling is safely away from other devices that might damage the cables.
For additional cabling guidelines, see the "Cabling Guidelines" section.
Install the Switch On a Desk or Shelf
Follow these steps:
Step 1 |
Locate the adhesive strip with the rubber feet in the accessory kit. |
Step 2 |
Remove the four rubber feet from the adhesive strip, and attach them to the recessed areas on the bottom of the unit. This prevents the switch from sliding on the desk or shelf. We strongly recommend that you attach the rubber feet. Doing so helps prevent airflow restriction and overheating. |
|
Step 3 |
Place the switch on the desk or shelf near an AC power source. |
Step 4 |
Use the supplied switch power cable to connect the switch to an AC power source. |
Step 5 |
Wait until the System LED blinks green and then turns solid green. A solid green SYSTEM LED means that the switch is operating properly. Troubleshooting: If the SYSTEM LED does not blink green, does not turn solid green, or turns amber, contact your Cisco representative or reseller. The switch failed the power-on self-test (POST). |
Install the Switch in a Rack
Prerequisite
Installing the Catalyst Express 520-8PC-K9 switch in a 19-inch rack requires 19-inch rack-mounting brackets and hardware that are not shipped with the switch. You can order a bracket kit from Cisco. The kit part number is RCKMNT-19-CMPCT=.
The other Catalyst Express switches ship with brackets and hardware.

The following guidelines are provided to ensure your safety: •This unit should be mounted at the bottom of the rack if it is the only unit in the rack. •When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. •If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006 |
Follow these steps:
Step 1 |
If you are rack-mounting a Catalyst Express 520-8PC-K9 switch, order the bracket kit from Cisco. The kit part number is RCKMNT-19-CMPCT=. For the other Catalyst Express switches, locate the brackets and hardware in the accessory kit. |
Step 2 |
Use the Phillips flat-head screws, included in the bracket kit, to attach a 19-inch bracket to each side of the switch. |
|
Step 3 |
After the brackets are attached to the switch, insert the switch into the 19-inch rack, and align the brackets in the rack. Use either the 10-32 pan-head screws or the 12-24 pan-slotted screws, included in the bracket kit, to secure the switch in the rack. We strongly recommend that you allow at least 1.75 inches (4 cm) of clearance above each switch in the rack. Use the supplied black Phillips machine screw to attach the cable guide to either bracket. Use the cable guide to secure the cables. This prevents them from obscuring the switch front panel and other devices in the rack. The cable guide is not used with the Catalyst Express 520-8PC-K9 switch. |
|
Step 4 |
Use the supplied switch power cable to connect the switch to an AC power source. |
Step 5 |
Wait until the System LED blinks green and then turns solid green. A solid green SYSTEM LED means that the switch is operating properly. Troubleshooting: If the SYSTEM LED does not blink green, does not turn solid green, or turns amber, contact your Cisco representative or reseller. The switch failed the power-on self-test (POST). |
