Figure 55 Install other power module models
NOTE:
•
If you install only one power module, install a filler panel over the empty power module slot to ensure
good ventilation.
• Before installing a PSR300-12A, PSR300-12A1, PSR300-12A2, PSR300-12D1, or PSR300-12D2 module
to the S5800-60C-PWR switch, make sure that the filler module is installed at the rear of the switch.
CAUTION:
•
To prevent damage to the power module or the connectors on the backplane, insert the power module
gently. If you encounter a hard resistance while inserting the power module, pull out the power module
and insert it again.
• If the captive screw cannot be tightly fixed, check the installation of the power module.
Removing a power module
To remove a power module except the LSVM1AC650, LSVM1DC650, LSVM1AC300, and
LSVM1DC300:
1. Wear an ESD-preventive wrist strap, ensure a good skin contact and make sure that the
ESD-preventive wrist strap is correctly grounded.
2. Switch off the power module and disconnect the power cord.
3. Loosen the captive screws of the power module with a Philips screwdriver until they are completely
disengaged.
4. Grasp the handle of the module with one hand and pull it out a little, support the module bottom
with the other hand, and pull the module slowly along the guide rails out of the slot.
NOTE:
•
Put the removed power module in an antistatic bag.
• The PSR150-A, PSR150-A1, PSR150-D, PSR150-D1, and PSR750-D power modules do not have a
power switch. You do not need to switch on and switch off the power module as described in the
installation and removal procedures in Figure 47 and Figure 48 .
