Removing the Power Cord Tray from a Rack or Cabinet for an EX8200 Switch
You can remove the power cord tray from a rack or cabinet. (The remainder of this topic
uses “rack” to mean “rack or cabinet.”)
In two-post rack installations, we recommend that you do not remove the power cord
tray unless you are also removing the switch and that you remove the switch before you
remove the power cord tray.
NOTE: The EX8216 switch can be installed only in a four-post rack. Installation in a
two-post rack is not supported.
If you remove the power cord tray before removing the EX8208 switch from a two-post
rack, there is no support for the underside of the switch. This creates a problem if and
when you need to remove the switch, because the chassis has no support once you
remove the screws that holdthe front-mountingbrackets tothe rack. In a four-post rack
this is not an issue because the switch rests on the adjustable mounting brackets.
Before you begin to remove the power cord tray:
•
Ensure no power cables are resting on or threaded through the power cord tray.
•
Remove the switch if the switch and power cord tray are installed on a two-post rack.
See “Removing an EX8208 Switch from a Rack or Cabinet” on page 201.
Ensure that you have the following parts and tools available to remove the power cord
tray:

1. Use the appropriate Phillips (+) screwdriver to remove the four mounting screws
that hold the power cord tray in the rack.
