Figure 4 Removing a power supply with a latch (AC)
Replacing a card
CAUTION:
•
The cards on the routers are hot swappable. However, to remove the only MPU on the router, you
must first power off the router.
•
To replace an MPU or service module, first remove all its cables.
•
Replace all Type-A switching fab r ic modules if one of them needs to be replaced. For more
information, see H3C CR16000-F Router Series Hardware Information and Specifications .
The replacement procedure is the same for the cards installed in horizontal or vertical slots. The
following procedure replaces a card in a horizontal slot.
To replace a card:
1. Prepare an antistatic mat to place the removed card.
2. Wear an ESD wrist strap and make sure it makes good skin contact and is correctly grounded.
For more information, see "Attaching an ESD wrist strap."
3. Use a Phillips screwdriver to loosen the captive screws on the card.
4. Press the ejector buttons on the ejector levers to release the ejector levers. (This step is
applicable only to a switching fabric module with ejector buttons on the ejector levers.)
5. Press the ejector levers down so that they are vertical to the front panel. (This step applies only
to ejector levers similar to those on a CSPEX-1504X card.)
6. Open the locking clip or micro switch, if any, on the module.
7. Move the ejector levers outwards to separate the card from the backplane.
8. 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.
9. Put the removed card on the antistatic mat.
