PS6500 Hardware Maintenance Maintaining Channel Cards
5-3
Channel Card Handling Requirements
Follow these channel card handling requirements:
• Protect channel cards from electrostatic discharge. When handling a channel card, always wear an
electrostatic wrist strap or a similar protective device. See Protecting Hardware from Electrostatic Discharge
on page 1-7.
• Handle channel cards carefully. Hold a channel card only by the plastic handle or latches. Do not force a
channel card into a slot.
• Store channel cards properly. Store a channel card in its original packaging or in an antistatic bag or place the
channel card on a surface protected from electrostatic discharge.
Replacing a Channel Card
You can replace a failed channel card without affecting array operation if the second card is installed and
functioning. Otherwise, if possible, cleanly shut down the array before removing the channel card, as described in
Shutting Down and Turning Off Power to an Array on page 1-13.
Notes: After you install a channel card, wait 60 seconds before removing the other channel card to allow the
channel cards to initialize.
For proper array cooling, minimize the time that the chassis cover is open.
Do not remove a failed channel card until you are ready to replace it.
Removing a Channel Card
1. Use an electrostatic wrist strap or a similar protective device. See Protecting Hardware from Electrostatic
Discharge on page 1-7.
2. Remove the bezel. See Removing and Installing the Bezel on page 1-8.
3. Unlock and open the chassis cover. See Opening and Closing the Chassis Cover on page 1-9.
4. Open the two channel card latches by rotating each latch upwards. This action will disengage the channel card
from the chassis. See Figure 5-3.
