Juniper MX960 User manual

Removing Components from the MX960 Chassis Before Installing It Without a Lift
If you cannot use a mechanical lift to install the router (the preferred method), you
can install it manually. Before installing the router manually, you must first remove
components from the chassis, and reinstall the components the router is installed
in the rack. With components removed, the chassis weighs approximately 150 lb
(68.04 kg).

Removing the Power Supplies Before Installing an MX960 Router Without a Lift
Remove the leftmost power supply first and then work your way to the right. To
remove the AC or DC power supplies for each power supply (see Figure 1):
1. 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 to an M Series, MX
Series, or T Series Router.
2. On an AC-powered router, move the AC input switch in the chassis above each
power supply to the off (O) position. On a DC-powered router, move the DC
circuit breaker on each power supply faceplate to the off (O) position.
We recommend this even though the power supplies are not connected to power
sources.
3. While grasping the handle on the power supply faceplate with one hand, use
your other hand to pull the spring-loaded locking pin in the release lever away
from the chassis and turn the release lever counterclockwise until it stops.
4. Let go of the locking pin in the release lever. Ensure that the pin is seated inside
the corresponding hole in the chassis.
5. Pull the power supply straight out of the chassis.
WARNING: Do not touch the power connector on the top of the power supply. It can
contain dangerous voltages.

Removing the Standard Cable Manager Before Installing an MX960 Router Without a Lift
To remove the standard cable manager (see Figure 2):
1. 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 to an M Series, MX
Series, or T Series Router.
2. Using a 7/16-in. (11 mm) nut driver, unscrew the nuts on the corners of the
standard cable manager.
3. Grasp the bottom of the standard cable manager and pull it straight out from
the studs on the front of the chassis.

Removing the Fan Trays Before Installing an MX960 Router Without a Lift
To remove the upper or lower fan tray (see Figure 3 and Figure 4, which illustrate
the upper and lower fan trays):
1. 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 to an M Series, MX
Series, or T Series Router.
2. Loosen the captive screw on each side of the fan tray faceplate.
3. Grasp both sides of the fan tray and pull it out approximately 1 to 3 inches.
4. Press on the two latches located on the inside of the fan tray to release the fan
tray from the chassis.
5. Place one hand under the fan tray to support it and pull the fan tray completely
out of the chassis.

Removing the SCBs Before Installing an MX960 Router Without a Lift
To remove the SCBs (see Figure 5):
1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to an approved site ESD grounding point. See the instructions
for your site.
3. Rotate the ejector handles simultaneously counterclockwise to unseat the SCB.
4. Grasp the ejector handles, and slide the SCB about halfway out of the chassis.
5. Place one hand underneath the SCB to support it, and slide it completely out of
the chassis. Place it on the antistatic mat.
CAUTION: Do not stack hardware components on one another after you remove
them. Place each component on an antistatic mat resting on a stable, flat surface.
6. Repeat the procedure for each SCB.

Removing the DPCs Before Installing an MX960 Router Without a Lift
To remove a DPC (see Figure 6):
1. Have ready an antistatic mat for the DPC. Also have ready rubber safety caps
for each DPC using an optical interface on the DPC that you are removing.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to an approved site ESD grounding point. See the instructions
for your site.
3. Simultaneously turn both the ejector handles counterclockwise to unseat the
DPC.
4. Grasp the handles, and slide the DPC straight out of the card cage halfway.
5. Place one hand around the front of the DPC and the other hand under it to
support it. Slide the DPC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.
CAUTION: The weight of the DPC is concentrated in the back end. Be prepared to
accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the DPC out of the chassis.
6■Removing the DPCs Before Installing an MX960 Router Without a Lift

When the DPC is out of the chassis, do not hold it by the ejector handles, bus bars,
or edge connectors. They cannot support its weight.
Do not stack DPC on top of one another after removal. Place each one individually
in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

Removing the FPCs Before Installing the MX960 Router Without a Lift
To remove an FPC (see Figure 7):
1. Have ready an antistatic mat for the FPC. Also have ready rubber safety caps for
each PIC using an optical interface on the PIC that you are removing.
2. 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 to an M Series, MX
Series, or T Series Router.
3. Simultaneously turn both the ejector handles counterclockwise to unseat the
FPC.

4. Grasp the handles and slide the FPC straight out of the card cage halfway.
5. Place one hand around the front of the FPC and the other hand under it to support
it. Slide the FPC completely out of the chassis, and place it on the antistatic mat
or in the electrostatic bag.
CAUTION: The weight of the FPC is concentrated in the back end. Be prepared to
accept the full weight—up to 18 lb (8.2 kg)—as you slide the FPC out of the chassis.
When the FPC is out of the chassis, do not hold it by the ejector handles, bus bars,
or edge connectors. They cannot support its weight.
