Inspecting the System
Do not unpack the RPM-XF front card and MGX-XF-UI back card until you are ready to install them. If the site is not ready, keep the cards in the shipping container to protect them. When you determine where you want to install the RPM-XF and the corresponding MGX-XF-UI back card and are ready to begin the installation, unpack the cards.
The RPM-XF, MGX-XF-UI, and any optional equipment you ordered might be shipped in more than one container. When you unpack each shipping container, check the packing list to ensure that you received all of the following items:
•MGX RPM-XF and MGX-XF-UI
Note Cisco Systems does not provide cables required to connect the back cards to external devices. These cables must be ordered from commercial cable vendors. For pinouts to these cables, see "Cable and Connector Specifications."
Cisco Systems also does not provide console and auxiliary cables in the RPM-XF or MGX-XF-UI kit. Console and auxiliary cables can be ordered as spares from Cisco Systems.
•Cisco Information Packet publication
•Cisco Documentation CD-ROM
•Optional printed publications, as specified on your order
Inspect all items for shipping damage. If anything appears to be damaged, or if you encounter problems when installing or configuring your system, contact the Cisco Technical Assistance Center (TAC).

Installing and Removing the RPM-XF Cards
The following sections describe how to install and remove the RPM-XF in the MGX 8850 midplane.
Note Installing and removing RPM-XF service modules is similar to installing and removing other service modules, such as an AXSM, which also goes into the midplane from the front of the MGX 8850 chassis.
Warning Only trained and qualified personnel should install or replace this equipment.
Warning Before handling the RPM-XF, attach a wrist strap.
Note It is not necessary to power OFF the MGX 8850 chassis. The RPM-XF can be removed and inserted in the MGX 8850 chassis while the system is up and running.
Before Installing Front or Back Cards
Before you install a front or back card, perform the following inspections.
•Inspect the backplane for bent pins or bent dividers between pin rows (see Figure 3-1).
If the backplane has bent pins, do not install a card in that slot. Installing a card into a damaged backplane slot will damage the connector on the card.
Figure 3-1 Backplane Inspection Check Points
•Inspect the card for damaged holes on the connector (see Figure 3-2).
If the connector has damaged holes, do not install the card. Installing a card that has a damaged connector will damage the backplane. Return damaged cards to Cisco Systems.

Installing the RPM-XF Front Card
Perform the following steps to install the RPM-XF in the MGX 8850 chassis.
Step 1 Position the rear edge of the card over the appropriate slot card guide at the top and bottom of the cage.
Note Verify that the intended slot for the card is the correct slot before you insert the card.
Step 2 Carefully slide the RPM-XF card all the way into the slot.
Step 3 Press both extractor levers until they snap into the vertical position.
Note The RPM-XF should slide in and out with only slight friction on the adjacent board EMI gaskets. Do not use force. Investigate any binding.
Removing the RPM-XF Card
Double-height front cards have a latch on the ejector at both the top and the bottom of the front panel. (See Figure 3-3.)
Warning To prevent damage to the cards from static electricity, put on a wrist strap and connect it to any convenient metal contact on the system or card cage before you touch any cards.
Figure 3-3 Front Card Extractor Latch
Perform the following steps to remove an RPM-XF front card from the MGX 8850 chassis.
Step 1 Press the tip of a small, flat-head screwdriver into the slot of the extractor lever (see Figure 3-3); press until the latch springs open, to approximately 10°.
Step 2 To separate the card from the backplane connector, pull the extractor lever(s) out.
Step 3 Gently pull the RPM-XF out along the guides. If it sticks, jiggle it gently.
Step 4 Carefully pull the card out of the card cage. Store it in an anti-static bag.
Note The RPM-XF slides along plastic guides into the front of the MGX 8850 system (see Figure 3-4) and connects to the chassis midplane. When removing the RPM-XF, you may feel some resistance as the midplane connector unseats.

Installing and Removing Back Cards in the MGX 8850 Midplane
The following sections describe how to install and remove the MGX-XF-UI management and high-speed uplink back cards (MGX-1GE and MGX-1OC12POS-IR) from the MGX 8850 midplane.
Installing the Back Cards
Use the following procedure to install the MGX-XF-UI management and high-speed uplink back cards in the MGX 8850 midplane:
Note Ensure that the two extractor levers are in the "in" position. When the card is being inserted into the slot, the levers should be vertical along the line of the back card.
Step 1 Position the rear card guides over the appropriate slot (directly behind the RPM-XF in the chassis) at the top and bottom of the card cage.
Note The MGX-XF-UI is always installed in the lower slot and the high-speed uplink back cards are always installed in the upper slot.
There are two connectors each with 360 pins, for a total of 720 pins. The top and bottom connectors are mechanically identical.
Step 2 Push the back card firmly but gently into the slot and then all the way into the connectors on the midplane.
Note Correct alignment between connector pins and receptacles is extremely important. First, make sure all pins on the card are straight. Make sure the connector on the card is aligned with the midplane connector. Insert the card gently. It may be necessary to push the card slightly to one side to achieve alignment.
Step 3 Tighten the two captive screws on the back card faceplate.
Tighten the upper and lower screws to prevent misalignment of the card. Do not overtighten the screws. Tighten only enough to secure the card.
Back cards installed in an MGX 8850 chassis and connected to the midplane are illustrated in Figure 3-5.
Note Figure 3-5 shows RPM-XF back cards in slots 9, 10, 11, and 12. You can see MGX-XF-UI cards in the bottom slots, MGX-1GE cards in slot 9 and 10, and MGX-1OC12POS-IR cards in slots 11 and 12.
Removing the Back Cards
Use the following procedure to remove the back cards from the MGX 8850 midplane.
Step 1 Label and remove any cables connected to the back card.
Step 2 Use a flat screwdriver to remove the two retaining screws in the back card faceplate.
Step 3 Pull both extractor levers out to the horizontal position.
This action will start the removal of the card.
Step 4 Gently pull the card out of the card cage.

Connecting a Console Terminal or PC to the MGX-XF-UI Console Port
The MGX-XF-UI management back card includes asynchronous serial console and auxiliary ports. These ports provide administrative access to the RPM-XF locally using a console terminal.
Use the following procedure to connect a terminal (an ASCII terminal or a PC running terminal emulation software) to the console port on the MGX-XF-UI.
Step 1 Connect the terminal (see Figure 3-6) using the thin, flat, RJ-45-to-RJ-45 rollover cable (which looks like a telephone cable) and an RJ-45-to-DB-9 or RJ-45-to-DB-25 adapter (labeled "Terminal") to the console port on the MGX-XF-UI.
For cable pinouts, see "Cable and Connector Specifications."
Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, and 1 stop bit.
Note The default parameters for the console port on the MGX-XF-UI are 9600 baud, 8 data bits, no parity and 1 stop bit.
