Correctly orient the power module with the power module slot (see Figure 27 ), grasp the handle
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.

Removing a power module
CAUTION:
When the switch has two power modules in 1+1 redundancy mode, removing one power module
does not affect the operation of the switch. When the switch has only one power module installed,
removing the power module powers off the switch.
Removing a PSR250-12A/PSR250-12A1 or PSR450-12A/PSR450-12A1 power module
The removal procedure is the same for the PSR250-12A/PSR250-12A1 and
PSR450-12A/PSR450-12A1 power modules. The following procedure removes a PSR250-12A
power module from an S6861-54QF switch.
To remove a PSR250-12A power module:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Remove the power cord.
3.
Hold the handle on the power module with one hand, pivot the latch on the power module to the
right with your thumb, and pull the power module part way out of the slot, as shown in
Figure 28 .
4.
Supporting the power module bottom with one hand, slowly pull the power module out with the
other hand.
5.
Put away the removed power module in an antistatic bag for future use.
