p690 更换DCA 看GUIDE的时候 对第4条看不大懂 希望专家给解释一下
1. Open the rack front door
2. Remove the I/O subsystem front cover.
3. Locate the DCA to be replaced.
4. Proceed only if all the DCA’s LEDs go off or the repair has been scheduled. If the repair has been scheduled, power off the system as described in “Powering Off and Powering On the System” on page 854, then return here. 5. Press the green Start Service button on the UEPO switch.
6. Proceed only if all the DCA’s LEDs go off or the repair has been scheduled (System outage - EPO off),
7. Verify the cable labeling and locations, and then unplug the cables from the DCA.
8. Loosen the left and right captive thumbscrews, using the torque tool (P/N 6422789), alternating between the fasteners until the unit can slide out of the slot.

是要在线换的，机器上跑的应用不能停 。之前看了一些帖子说有一定风险，比如微码级别等。如果在线换的话HMC里边用不用做些什么操作呢，具体怎么做呢？还有就是如果DCA的灯都灭了的话是可以直接更换的对吗？收起

P595上的DCA我换过，只要找准位置，按照HMC里面有guide一步一步来操作即可。收起
