Installing a Card
Context
- Cover all the vacant slots with filler panels to ensure good electromagnetic shielding, heat dissipation, and dustproof performance.
- Wear an ESD wrist strap or a pair of ESD gloves when you install cards. Do not touch a card with bare hands.
- When installing a card, push the card slowly and horizontally into a slot along guide rails in the slot to protect components on the cards from collisions. Ensure that the card is securely installed in the slot.
- Main control units of different models cannot be used in the same chassis.
- Switch fabric units of different models cannot be used in the same chassis.
The following installation procedure applies to MPUs, LPUs, and SFUs.
For details about the OSP card and the installation procedure, see the OSP Board Quick Start.
Procedure
- Wear an ESD wrist strap or a pair of ESD gloves. When wearing an ESD wrist strap, insert the other end in the ESD jack of a device and ensure that the device is reliably grounded.
- Remove the filler panel from the slot and save the filler panel for later use. See Figure 8-3.
- Take out the card from the ESD bag and rotate the ejector levers outward. With one hand beneath the card, use the other hand to grasp the panel of the card and slowly slide the card along the guide rails, until the hooks of the ejector levers are attached to the interior sides of the slot. See callout 1 in Figure 8-4.
- Close the ejector levers and push them until the card cannot move forward. See callout 2 in Figure 8-4. You will hear a click from the ejector levers when the card is completely seated in the slot.
A Centralized Monitoring Unit (CMU) has no ejector levers, and you can insert it directly into a CMU slot.
- (Only for a CMU) Use a Phillips screwdriver to tighten the captive screws on the panel. See Figure 8-5.
- Install filler panels on all the vacant slots.
