Replacing a card
The card replacement procedures for the S7500E series are the same.
NOTE:
Remove the cables on an SRPU or LPU before removing the SRPU or LPU.
To replace a card:
1. Prepare an antistatic mat to place the removed card.
2. Wear an ESD wrist strap and make sure it has a good skin contact and is well grounded. For more
information, see " Installing FRUs ."
3. Use a Phillips screwdriver to remove the captive screw on the card, as shown in callout 1 on Figure
50 .
4. Move the ejector levers outwards to separate the card from the backplane, as shown in callout 2
on
Figure 50 .
5. Use one hand to slowly move the card outwards. Supporting the bottom of the card with the other
hand, pull the card out of the slot along slide rails, as shown in callout 3 on
Figure 50 .
6. Put the removed card on the antistatic mat.
7. Install a new card. For the installation procedures, see " Installing FRUs ."
If no new card is to be installed, install a blank panel to ensure heat dissipation of the switch and
prevent dust from entering the switch.
