Installing the MGX 8830 or MGX 8830/B Switch

Install the AC Power Supply Tray(s)

Complete the following steps to install the AC power supply tray(s).
Note MGX8830-AC= is a 1200W, 1U Power Supply. Starting with MGX Release 4, an AC-DC cable is added
to allow you the option of upgrading the MGX 8830 DC system to AC. The Cisco Part Numbe r for the
MGX 8830 tray is MGX8830-AC-TRAY=.
The AC power supply modules slide into the AC power supply tray from the rear of the
Cisco MGX 8830. As seen from the front of the chassis, the AC Power Supply A (PSA) is on the left and
the AC Power Supply B (PSB) is on the right. The front grill of the AC power supply tray has cutouts
that allow the AC OK and DC OK LEDs on the AC power supply modules (PSA and PSB) to be seen.
Note The AC power supply tray is optional.
Complete the following steps to reinstall the AC power supply module s:
Step1 From the rear of the chassis, slide a 1200 watt AC power supply module into the AC power supply tray.
Step2 Secure the set screw on the top of the AC power supply module to secure it in the AC power supply tray.
Step3 Repeat Step 1 and Step 2 for the second 1200 Watt power supply module, if applicable.
Note If only one AC power supply module is used in your system, make sure that the slot for the other AC
power supply module is covered with a blank faceplate.
Note For optimum performance, it is recommended that you install dual AC power systems for full
redundancy.
Install the MGX 8830 Switch without a Mechanical Lift
Caution Because of the risk of damage to the cards, modules, and backplane, it is strongly recommende d that a
mechanical lift be used. Using a lift greatly simplifies the installation and reduces the risk of damage.
See “Install the MGX 8830 Switch with a Mechanical Lift” section on page5-118 for more information
about installing the MGX 8830 switch with a mechanical lift.
If a mechanical lift is not available for installation, the switch must be manually lifted into place. Since
the switch is shipped with all components preinstalled, you must remove the cards and modules from the
switch so that you can lift it into the rack.
The following sections contain instructions for installing a switch without the use of a mechanicallift:
•“Prepare for Installation” section on page 5-110
•“Remove the Front Cards” section on page 5-110
•“Remove the Back Cards” section on page 5-111
