Installing a Multiservice Switch 7420 into a rack or cabinet
Install a Nortel Networks Multiservice Switch 7420 into a rack or cabinet, as
an alternative to mounting the device on the floor or desktop.
Prerequisites
• If your device requires seismic protection, see “Installing a Multiservice
Switch 7420 into a seismic rack or cabinet” (page 275)
• You need a rack-mount kit with PEC NTHQ04.
• The rack or cabinet must already be anchored and grounded. For more
information, see
“Cabinet installation” (page 105).
• If you plan to install the device in a cabinet, check the position and
alignment of the vertical rails. Set the front rails 11.4cm (4.5 inches) from
the front of the cabinet. Set the front and rear vertical rails 36.8 (14.5
inches) apart.
• Install 13” termination panels prior to installing the device in a rack or
cabinet.
• Ground yourself to an appropriate anti-static discharge apparatus while
handling the shelf assembly (device).
Procedure steps
1 Attach the rack mount brackets to each side of the chassis using a
screwdriver. Attach the cable management bracket to the fan-less side of
the chassis. See the figure “Securing the rack-mounting brackets to the
Multiservice Switch 7420” (page 273)
2 Position the chassis in the rack or cabinet.
3 Fasten the front brackets to the rack’s front rails using the four screws
provided. See the figure
“Securing the rack-mounting brackets to the front
vertical rails” (page 274)
CAUTION
Risk of equipment damage
You need two people to install a Multiservice
Switch
7420 in a rack or cabinet: one person must hold
the chassis in place while a second person fastens the
screws.
