Installing an NPC in an SRX1400 Services Gateway
The SRX1400 Services Gateway is not normally equipped with an NPC. In most configurations, network processing functions are performed by the NSPC.
You can install an NPC in the front-panel slot labeled 3 if you also install an SPC in the slot labeled 1. This combination of SPC and NPC replaces the full-width
NSPC that is normally installed in the SRX1400 Services Gateway to
perform both services processing and network processing functions.
If a slot is not occupied by a card, you must install a blank panel to shield the empty slot and to allow cooling air to circulate properly through the services gateway.
To install the NPC and SPC on the SRX1400 Services Gateway, you must order the double-wide tray (SRX1K3K-2CFM-TRAY) to hold the two single-wide CFMs (NPC and SPC) separately. Contact your Juniper Networks customer service representative for more information.
To install an NPC:
- Attach an 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 the SRX1400 Services Gateway.
- Place the card on an antistatic mat or remove it from its electrostatic bag.
- If necessary, remove the filler cover from the slot by loosening its screws and sliding it out of the slot.
- Insert the double-wide tray and insert it straight into
the slot until you hear a click, indicating the latch has closed as
shown in Figure 1.

- Orient the NPC so that the faceplate faces you. Slide
the NPC all the way into the card cage until you feel resistance.

- Tighten the screws on either side of the card.
You can proceed with installing other hardware components, or power supplies, or connecting to a management device. See Powering On the SRX1400 Services Gateway to power on the SRX1400 Services Gateway.
Never lift the services gateway using the handles on the front panels of the NPC or other CFM cards. The handles might come off, causing the chassis to drop and inflicting possible grave injury.
