Chapter6 Maintaining the Cisco MGX Switch or Gateway
Removing and Installing the Back Cards
Caution Proper ESD protection is required whenever you handle Cisco equipment. Ins tallation and maintenance
personnel should be properly grounded through the use of ground ing straps to eliminate the risk of ESD
damage to the equipment. Modules are subject to ESD dam age whenever they are removed from
the chassis.
Caution If the AXSM-1-2488 or AXSM-1-2488/B front cards are ins talled with incorrect back cards, you may
damage the cards.
Caution To prevent damage to components on the bottom side of a card, support the facep late and keep the card
level while sliding it into the chassis.
Caution Cards must be inserted in the correct slot positions. If service module back cards are installed in the
wrong slots, electrical damage can occur. If a service module back card is inserted int o a PXM back card
slot, damage to the card and backplane can result.
Caution If you accidentally attempt to insert a service modul e back card into a PXM back card slot and then have
difficulty operating the chassis, examine the backplane pins and back card connector to see if they have
been bent or damaged.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 142
Remove the Back Cards
Complete the following steps to remove back cards from the chassis:
Step1 Connect a grounding strap to the ESD grounding jack.
Step2 Mark and disconnect all cables and wires from the back card .
Step3 Use the flat-head or Phillips tip of the 3-in-1 tool to loosen the two captive screws located on the top and
bottom of the back card faceplate.
Step4 Pull each of the two extractor levers, located at the top and bottom of the faceplate, out to the
horizontal position. These levers are at the left and right side of t he faceplate in an MGX 8830 switch.
Note The SMFXX-4-2488-SFP and SMFXX-1-9953 double-height back cards have a single threaded
screw instead of extractor levers.
