The v1 seems to share its PCB and case with non-PoE GS1900-8; the
v2 with
its already supported bigger brother, the GS1900-10HP - its board
looks the
same, except for two holes where the GS1900-10 has its SFP ports.
Like their 10 port sibling, both devices have a dual firmware
layout.
Both GS1900-8HP boards have the same 70W PoE+ power budget.
Specifications (v1)
-------------------
* SoC: Realtek RTL8380M 500 MHz MIPS 4KEc
* Flash: Macronix MX25L12835F 16 MiB
* RAM: Nanya NT5TU128M8HE-AC 128 MiB DDR2 SDRAM
* Ethernet: 8x 10/100/1000 Mbit
* PoE+: Broadcom BCM59111KMLG (IEEE 802.3at-2009 compliant, 2x)
* UART: 1 serial header with populated standard pin connector
on the
left side of the PCB, towards the bottom. Pins are
labeled:
+ VCC (3.3V)
+ TX
+ RX
+ GND
Specifications (v2)
-------------------
* SoC: Realtek RTL8380M 500 MHz MIPS 4KEc
* Flash: Macronix MX25L12835F 16 MiB
* RAM: Samsung K4B1G0846G 128 MiB DDR3 SDRAM
* Ethernet: 8x 10/100/1000 Mbit
* PoE+: Broadcom BCM59121B0KMLG (IEEE 802.3at-2009 compliant)
* UART: 1 angled serial header with populated standard pin
connector
accessible from outside through the ventilation slits
on the
side. Pins from top to bottom are clearly marked on
the PCB:
+ VCC (3.3V)
+ TX
+ RX
+ GND
Connection parameters for serial on both devices: 115200 8N1.
Installation
------------
* Configure your client with a static 192.168.1.x IP (e.g.
192.168.1.10).
* Set up a TFTP server on your client and make it serve the
initramfs
image.
* Connect serial, power up the switch, interrupt U-boot by hitting
the
space bar, and enable the network:
# rtk network on
* Since the GS1900-10HP is a dual-partition device, you want to
keep the
OEM firmware on the backup partition for the time being. OpenWrt
can
only boot off the first partition anyway (hardcoded in the DTS).
To
make sure we are manipulating the first partition, issue the
following
commands:
# setsys bootpartition 0
# savesys
* Download the image onto the device and boot from it:
# tftpboot 0x84f00000
192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-
8hp-initramfs-kernel.bin
# bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and
flash it:
# sysupgrade /tmp//tmp/openwrt-realtek-generic-zyxel_gs1900-8hp-
squashfs-sysupgrade.bin
