Installing a Stack Card

Ensure that the following components and tools are available before the installation:

• Component: ES5D21VST000 rear stack card
• Tools: Phillips screwdriver, ESD wrist strap or ESD gloves

Card Storage and Transfer

• Handle a stack card carefully when it is outside the chassis. Wear an ESD wrist strap or ESD gloves when touching the stack card. Place the stack card on a horizontal plane, with the electronic components facing upward. Do not place any objects on or near the card.
• Keep a stack card from heavy humidity or direct sunlight. Ensure that the card is stored in an environment that will not cause damages to the card.
• To move multiple stack cards, move one card each time. Do not stack the cards together when moving them.

Card installation and removal

• Wear an ESD wrist strap or ESD gloves when installing or removing a stack card. Do not touch the printed circuit board (PCB) on the card.
• Gently, slowly pull or push the stack card along the guide rails. Avoid short-circuit conditions on the card caused by collision with metal materials or improper use of tools.

Perform the following steps to install a stack card:

1. Wear an ESD wrist strap and connect the other end of the strap to the ESD jack on the cabinet.
2. Power off the switch and remove the filler panel from the rear card slot.
3. Install the stack card in the rear card slot, close the ejector levers on the stack card, and fasten the captive screws. See Figure 1.
