Introducing the GigaSpire BLAST u4hm
The Calix GigaSpire BLAST u4hm (GM1028H) is a new generation, dual-band, outdoor PoE
or local powered Wi-Fi 6 mesh system, ideal for residential applications, bringing high-
bandwidth services outdoors to the barn, patio, pool, and more. It features the latest Wi-Fi 6
technology, offering the optimal Wi-Fi experience. Besides supporting data and video
services, this intelligent, high-performance system has GE LAN and WAN interface,
allowing it to support Gigabit throughput for video and data services.
The GigaSpire BLAST u4hm is a dual-band, outdoor PoE or local powered Wi-Fi 6 system
that leverages the 2.4 and 5 GHz spectrum. Using a Gigabit Ethernet interface supporting
either WAN or LAN allows broadband service providers (BSPs) to provide high bandwidth
for the most demanding environments.
With integrated power of Ethernet (PoE), the GigaSpire BLAST u4hm can be placed in an
optimal location; even without power availability. Coupled with the Calix GigaPro
GPR8802x, the GigaSpire BLAST u4hm can be powered via an Ethernet cable. In addition,
the GigaSpire BLAST u4hm can also be powered locally (with a traditional power adapter),
offering the ultimate outdoor location flexibility.
u4hm Satellite
Key attributes of the hardened u4hm include the following:
Environmentally hardened system for outdoor operation in extreme conditions
Layer 2 bridge and Layer 3 routing for High Speed Internet (HSI) data and IPTV
video services
2.4 GHz and 5 GHz 802.11ax (Wi-Fi 6) certified, 802.11a/b/g/n/ac compatible
WPA/WPA2/WPA3; WEP 64/128 bit encryption

Dynamic Mesh: load balancing, band/node steering; interference management
Remote WAN side GUI access
Gigabit Ethernet LAN/WAN interface; single port of multi-rate 10/100/1000
BASE-T Ethernet, auto-negotiating for residential IPTV and data services
Dynamic Mesh: load balancing, band/node steering; interference management
Supports a Power of Ethernet (PoE) input power option on its Gigabit WAN port to
operate as a PoE Powered Device (PD); or can be powered locally with a traditional
AC/DC power adapter.

Mounting Options
Currently, there are two methods for mounting the u4hm:
Wall Mount (on page 25) - The u4hm wall mount bracket is standard equipment on the
GM1028H. Mounting instructions (on page 25) are included in this guide.
Pole Mount (on page 28) - A pole mount bracket kit can be ordered separately.
100-05967 Pole mount bracket for GigaSpire BLAST GM1028H (u4hm)
Additional Mounting Considerations
From a best practice’s standpoint, keep the following in mind:
Calix recommends mounting the BLAST u4hm as high as practical for Wi-Fi
performance reasons. However, this deployment scenario still mandates that an AC
power outlet is located within the power cord distance of the Wi-Fi source. If installing in
a greenfield environment (initial installation), plan on placing the GM1028H within 10
feet of the power supply. As an alternative, longer power cords are available to extend the
distance between the u4hm and the power supply.
Calix also recommends keeping cabling neat and well secured wherever possible. A tidy
installation allows for increased safety and an overall neater appearance. Common tools
used for this purpose include cable ties and velcro straps for routing cable out of the way.
Also, custom made wall plates may be used where the majority of cabling is hidden
behind a wall.
27 inch/pounds of torque or less should be used when tightening fasteners to both the
bracket and the u4hm.

Powering Options
Attach to any 110/220 VAC power outlet using the supplied 12 VDC transformer.
Note: For the GM1028H, the power cord configuration must be appropriate for use in
the country where the device is being deployed.
Note: Only provided and approved power cords or voltage adapters should be used to
connect to this product.
The power supply provided is suitable for both indoor and outdoor deployments and
provides the following:
Ext. Power Adapter: 12 VDC, 3A
AC Power Cord (from incoming line voltage power): 10 feet (3 meters)
DC Power Cord (to u4hm): 6 feet (1.8 meters)
2-pin barrel connector to u4hm
Input voltage: 12 VDC (nominal), 10 VDC (min.), 15 VDC (max)
PoE 802.3bt PD
Power Supply (3-pin)

PoE Power Option
DC Power Option - An RJ-45 Ethernet connector for Powered Devices (PD) that provides
input to the 802.3BT compliant Power over Ethernet (PoE) system.
PoE - Supports personal devices only on the WAN uplink.
Daisy chain uplinks to any satellite unit are supported from the LAN port but not the
PoE port.
When employing PoE, added hardware specific to this powering option are not
provided by Calix nor does Calix recommend any specific solution.
If additional help is needed on implementing a power supply, please contact your
local Calix service professional.

MISE EN GARDE! L'utilisation de commandes ou de réglages ou l'exécution de
procédures autres que celles spécifiées ici peuvent entraîner une exposition à
des rayonnements dangereux.
Note: Before mounting the u4hm to a wall or pole, complete all internal wiring. Once the
u4hm is attached, very little room exists due to mounting bracket interference.
Follow these tips when installing a GigaSpire BLAST GM1028H device:
For subscribers using data services, all data wiring inside the home must be CAT5 cable
or better.
Make sure subscriber connections are tightened properly.
Check the contents of each box carefully as you receive them. Components may not be
located where you might expect them due to certain items being tested immediately before
shipment.
