CAUTION: Do not touch the electronic components or the
connectors on the backplane or on the circuit
boards without being electrically grounded.
Handle circuit boards by their edges only.
Electrostatic discharge can damage circuits, even
if you cannot feel, see, or hear it.
5. Place the removed board on an anti-static surface or in an anti-
static container.
6. For an I/O board, orient the board to be installed so that
connector A (of either the input group of connectors or the
output group of connectors) is on the left and connector D (of the
same group of connectors) is on the right.
7. For an I/O board, align the board with the left and right chassis
guides (above).
8. Gently slide the board or blank panel into the enclosure. For an
I/O board, slide the board toward the front panel until it meets
resistance.
9. Gently seat the board or panel in the backplane.
10. Tighten the left and right knurled knobs to lock the board or
panel in place. Use a screwdriver to tighten the knurled knobs.

Removing and Installing a Power Supply Module

The two power supply modules (primary power supply and redundant
power supply) are identical and hot-swappable. Each power supply
module has a 2-color LED, visible on the rear panel, that indicates the
status of the power supply outputs. If the LED is lit green, the power
supply is operating normally. If the LED is lit red, the supply has
failed and should be replaced at the earliest opportunity. LEDs with
identical meaning are also on the front panel.

not need to power down the switcher to install or remove
either power supply module.

captive screws (see the figure below).
