Installing/removing a power module
WARNING!
In power redundancy mode, you can replace a power module without powering off the switch but must
strictly follow the installation and removal procedures in
and
to avoid bodily injury
or switch damage.
CAUTION:
Provide a circuit breaker for each power module.
The switch comes with both power module slots empty and the power filler modules as accessories.
You can install one or two power modules for these switches as needed. For more information about the
power modules available for the switches, see "

Installing a power module
CAUTION:
•
Do not install LSVM1AC300/LSVM1DC300 and LSVM1AC650/LSVM1DC650 power modules on the
same switch.
•
Follow the forward inertia of the power module when inserting it into the chassis, and make sure the
power module has firm contact with the connectors on the backplane.
•
To prevent damage to the connectors inside the switch chassis, 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.
•
For good ventilation of the switch, install a filler module in the empty power module slot.
To install an LSVM1AC650, LSVM1DC650, LSVM1AC300, or LSVM1DC300 power module into the
switch:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the power module and verify that the power module model is correct.
3.
Correctly orient the power module with the power module slot (see
of the power module with one hand and support its bottom with the other, and slide the power
module slowly along the guide rails into the slot.
The slot is foolproof. If you cannot insert the power module into the slot, re-orient the power module
rather than use excessive force to push it in.
