(Optional) Installing a CSS Subcard or an Enhanced Flexible Service Subcard

(Optional) Installing a CSS Subcard or an Enhanced Flexible Service Subcard

Context

If a Cluster Switching System Service (CSS) subcard or an enhanced flexible service subcard is configured for a card, install the subcard on this card before you install the card in the chassis. For the S7700&S9700, CSS subcards or enhanced flexible service subcards are installed in subcard slots of MPUs.

  • CSS cards and enhanced flexible service units (except the ES1D2VS04000) are not hot swappable.
  • To install a CSS subcard or an enhanced flexible service subcard that does not support hot swap in a running MPU, power off the MPU first.
NOTE:

The methods for installing a CSS subcard and an enhanced flexible service subcard are the same. An S9700 CSS subcard is used as an example here.

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Phillips screwdriver
  • 50 cm x 50 cm ESD fabric

Procedure

  1. Lay the ESD fabric on a desk or another flat surface. Use the ESD bag of a card as a substitute if no ESD fabric is available.
  2. 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.
  3. Take out the motherboard (such as an MPU) from the ESD bag and place the motherboard on the ESD fabric.
  4. Install a CSS subcard.
    1. Take out the CSS subcard from the ESD bag and rotate the ejector levers outward. Hold the panel of the CSS subcard and slowly insert the CSS subcard into the subcard slot, until the hooks on the ejector levers hook on the interior side of the slot. See callout 1 in Figure 8-2.
    2. Rotate the ejector levers inward until the CSS subcard is completely seated in the subcard slot. See callout 2 in Figure 8-2.
    3. Use a Phillips screwdriver to tighten the captive screws on the CSS subcard. See callout 3 in Figure 8-2.

    Figure 8-2  Installing a CSS subcard
    NOTE:

    The ES02VSTSA CSS subcard and ES0D00FSUA00 enhanced flexible service subcard do not have ejector levers. Push them directly into the subcard slot.
