Chapter 3 Installing the Switch
Install the Switch in a Rack
3-10
User Guide for the Catalyst Express 520 Switches
OL-12761-02
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).
