On an AC-powered services gateway, switch the circuit breaker on each power

When removing or inserting an SCB, ensure that the SCBs or blank panels in
adjacent slots are fully inserted to avoid hitting them with the ejector handles.
The ejector handles require that all adjacent components be completely inserted
so the ejector handles do not hit them, which could result in damage.
The ejector handles have a center of rotation and need to be stored toward the
center of the board. Ensure the long ends of the ejectors located at both the top
and the bottom on an SRX 5800 services gateway, left and right on an SRX 5600
services gateway of the board are horizontal and pressed as far as possible
towards the center of the board.
To insert or remove the SCB, slide the ejector across the SCB horizontally, rotate
it, and slide it again another quarter of a turn. Turn the ejector again and repeat
as necessary. Utilize the indexing feature to maximize leverage and to avoid
hitting any adjacent components.
Operate both ejector handles simultaneously. The insertion force on an SCB is
too great for one ejector.
Power off the device. See "Powering Off the Services Gateway" on page 4.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. For more information
about ESD, see "Preventing Electrostatic Discharge Damage" on page 8.
Rotate the ejector handles simultaneously counterclockwise to unseat the SCB.
Grasp the ejector handles and slide the SCB about halfway out of the chassis.
Place one hand underneath the SCB to support it and slide it completely out of
the chassis.
Place the SCB on the antistatic mat.
If you are not replacing the SCB now, install a blank panel over the empty slot.
