Install the MGX 8230 Without a Mechanical Lift (Optional)

Because of the risk of damage to th e mo du le s and backplanes, Cisco strongly r eco m me nds the use of a

mechanical lift. Using a lift gr eatly simplifies the installatio n and reduces the risk of damag e. See Install

the MGX 8230 Using a Mechan ic al L ift (Recommended), page 4-6.

If a mechanical lift is not availabl e f o r in stallation, the MGX 8230 must b e m an ua lly lifted into place.

Since the MGX 8230 is shipped with all equipment pre-installed, you may have to remove some of the

service modules, the AC Power Supply Modules, or the Fan Tray Assembly to more easily lift the chassis

into the rack.

This section contains inst ru ct io ns to install a MGX 8230 c ha ss is w i thout the use of a mechani cal lift.

Review the following points before installation is begun:

•Handle the PXM front card very carefully. This card contains a disk drive that is easily damaged.

Cisco recommends no t r e m oving the PXMs.

•Before removing any modules or assemblie s, Cisco suggests th at you carefully not e and write down

their location or slot number i n the chassis.

•The MGX 8230 includes a grounding wrist strap to protect the user and the electronic components

from electrostatic shock. This strap can be connected to the lower rear corner near the grounding

lug, or to the front panel.

•Inserting the cards in the co rrect slot. If back cards are ins talled in the wrong slot, elect rical damage

may occur. If a back card is inserted into a PXM back slot (1 o r 2), damage to the card and backplane

can result. Never remove or insert either ca r d i n a P X M /SO N E T b ack c ard set with the power on.

•If a service module back card is accidently inserted into slots 1 or 2 and then removed, check for

bent or broken pins on the backplane. Such damage can result in faulty operation of the switch.

•Both the front card and the corresponding back card of all card sets must be installed for proper

operation.

•If a back card is removed, reseated or changed f or another back card, the associated front car d must

be reset.

The front cards are held in place by a mechanical latch attached to the ca rd . Th e t op o f a f r on t card

corresponds to the left side of the MGX 8230 card cage as seen from the front, as shown in Figure4-4.
