Prerequisites
During installation, maintenance, and/or removal, wear a grounding wrist strap connected to the ASR
5500 chassis to avoid ESD damage to the components. Failure to do so could result in damage to sensitive
electronic components and potentially void your warranty.
Caution
Save several of the shipping cartons and ESD protective bags for use if a card must be returned to Cisco
for fault analysis.
Important
On a chassis equipped with the cable management tray, you must lower the tray to insert rear circuit cards.
Refer to the Lowering the Cable Management Tray section in the Cable Management System Installation
appendix. The cable management tray can be installed after all rear cards have been installed.
Important
Install cable management brackets on MIO cards before inserting the card into the chassis. Refer to the
Installing Cable Management Brackets section in the Cable Management System Installation appendix.
Important
Installing Circuit Cards
Step 1
Determine the type of card you are installing. The card type is identified by the label within the bottom ejector handle
of the card.
Step 2
Determine in which chassis slot to install the card based on the information in the tables at the beginning of this chapter.
Step 3
Install front cards from Right to Left. Complete the installation sequence described in Steps 5 through 9 for each card
before proceeding to the next card. This includes tightening the captive screws in the ejector handles using a Phillips #2
screwdriver.
Step 4
Install rear cards from Left to Right. Complete the installation sequence described in Steps 5 through 9 for each card
before proceeding to the next card. This includes tightening the captive screws in the ejector handles using a Phillips #2
screwdriver.
Step 5
Position both ejector handles on the circuit card to be up and away (outwards) from the front panel of the card.
Step 6
Properly support the weight of the card and align it with the upper and lower card guides of the chassis slot. Gently slide
the card into the slot until the levers touch the chassis frame.
When installing cards that contain heat sinks, avoid any contact with an adjacent card. Such contact may
loosen a heat sink as the card is being slid into the chassis slot.
Important
Never use a cable management bracket on an MIO /UMIO card to lift or insert the card into the chassis. The
bracket is not designed to support the weight of the card.
