SRX650 Services Gateway Services and Routing Engine 6

 

The Services and Routing Engine (SRE) module provides processing power for security services, routing protocol processes, and other software processes that control the services gateway interfaces, some of the chassis components, system management, and user access to the device.

The services gateway must have one SRE installed.

Caution

The SRE is not hot-swappable. You must power off the services gateway before removing or inserting an SRE.

The SRE installs horizontally in the back of the chassis in slots SRE0 or SRE1/SRE1.1. An SRE weighs 3 lb 13.6 oz (1.75 kg).

Note

Slot SRE0 is a full-length slot capable of holding a full slot module such as an SRE. The SRE1 and SRE1.1 slots are capable of holding either two half slot modules or one full slot module.

If a slot is not occupied by a card, a blank panel must be installed to shield the empty slot and to maintain proper cooling of the services gateway.

Figure 1 shows the front of the SRE.

CompactFlash port

Slot that accepts removable type I or II CompactFlash cards, as defined in the CompactFlash Specifications published by the CompactFlash Association. When the removable CompactFlash card is installed and configured, it automatically acts as the secondary boot device if the primary CompactFlash card fails on startup.

Depending on the capacity of the removable CompactFlash card, you can also configure it to receive any core files generated during a failure.

The services gateway supports the following CompactFlash cards:

  • STEC 2 GB

  • Wintec 2 GB

USB 0 and USB 1 ports

The SRE has two USB ports, labeled USB 0 and USB 1, that accept a USB storage device. When the USB drive is installed and configured, it automatically acts as the secondary boot device if the primary CompactFlash card fails on startup.

Note: You must install Junos on the USB storage device to use it as the secondary boot device. The services gateway supports the following USB devices:

  • Sandisk Micro Cruzer 2 GB

  • Lexar 2 GB

Depending on the capacity of the USB drive, you can also configure it to receive core files generated during a failure.
