(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 S9300&S9300E, CSS subcards or enhanced flexible service subcards are installed in subcard slots of MPUs.
- CSS cards and enhanced flexible service units (except the LE1D2VS04000) 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 S9300 CSS subcard is used as an example here.
Procedure
- 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.
- 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.
- Take out the motherboard (such as an MPU) from the ESD bag and place the motherboard on the ESD fabric.
- Install a CSS subcard.
- Take out the CSS subcard from the ESD bag. Hold the panel of the CSS subcard and slowly insert the CSS subcard into the subcard slot in the MPU. See callout 1 in Figure 8-2.
- Use a Phillips screwdriver to tighten the captive screws on the CSS subcard. See callout 2 in Figure 8-2.
